As a leading bearing manufacturer with over 60 years of industry expertise, E-ASIA Bearing delivers precision roller bearings that excel in radial load capacity while maintaining minimal friction coefficients. These heavy-duty cylindrical bearings feature optimized internal geometry, utilizing line contact between rollers and raceways to distribute loads across larger surface areas compared to traditional ball bearings. Unlike standard bearing solutions that compromise under extreme operational conditions, our industrial-grade roller bearings incorporate advanced metallurgical treatments and precision grinding techniques, ensuring consistent performance in steel mills, mining machinery, and metallurgical plants. For production facilities requiring reliable power transmission components, these bearings deliver exceptional operational stability and extended service life.
Core Features
Superior Radial Load Capacity
Our high-capacity cylindrical roller bearings utilize full-complement roller designs or optimized roller spacing to maximize radial load handling. The linear contact geometry distributes forces evenly across roller length, enabling these bearings to support loads 30-40% higher than equivalent ball bearings. This makes them ideal for heavy machinery bearings in rolling mills, mining crushers, and industrial gearboxes.
Precision Manufacturing Standards
Every bearing undergoes ultra-precision grinding operations using advanced CNC machines, achieving surface roughness values below Ra 0.2μm. Our quality control processes include 100% dimensional inspection and vibration testing, ensuring each precision cylindrical bearing meets strict ISO 492 tolerances. This precision translates to reduced vibration, lower noise levels, and smoother operation in critical applications.
Detachable Design for Easy Maintenance
Most models feature separable inner and outer rings, simplifying installation and maintenance procedures. Technicians can mount bearings on shafts independently before positioning housings, reducing downtime during equipment servicing. This modular bearing design proves particularly valuable in continuous production environments where maintenance windows are limited.
Multiple Seal Configurations
We offer open bearings for external sealing systems, as well as integrated seal designs (single or double shields/seals) for contaminated environments. Sealed protected roller bearings prevent ingress of dirt, moisture, and abrasive particles—critical for mining equipment, construction machinery, and outdoor applications where environmental protection extends bearing lifespan.
Enhanced Cage Technology
Our bearing cages employ optimized geometries that maintain precise roller spacing while minimizing friction losses. Steel cages provide maximum strength for shock loading conditions, brass cages offer superior heat dissipation, and polyamide cages reduce weight while resisting chemical degradation. This advanced cage design ensures stable roller guidance across varying operational conditions.
Typical Uses
Steel Manufacturing and Rolling Mills
In steel production facilities, rolling mill bearings endure extreme radial loads from work rolls and backup rolls. Our cylindrical roller bearings handle the combined stresses of metal forming operations, maintaining dimensional accuracy even under cyclical loading patterns. They're essential components in hot strip mills, cold rolling mills, and continuous casting equipment.
Mining and Mineral Processing
Mining machinery bearings must withstand severe shock loads, contamination, and continuous operation cycles. Our heavy-duty designs support crushers, grinding mills, conveyor systems, and excavators. Enhanced sealing configurations protect internal components from rock dust and moisture, significantly extending maintenance intervals in harsh mining environments.
Wind Energy Generation
Modern wind turbines require renewable energy bearings that balance load capacity with operational precision. Cylindrical roller bearings support generator shafts and gearbox intermediates, handling fluctuating wind loads while maintaining rotational accuracy. Our special heat treatment processes ensure reliable performance throughout 20+ year turbine lifespans.
Machine Tools and Manufacturing Equipment
Precision manufacturing demands machine tool bearings with minimal runout and high rigidity. Our P5 and P4 tolerance class bearings support spindles, rotary tables, and CNC machine components, enabling tight machining tolerances. The high stiffness of cylindrical roller contact prevents deflection under cutting forces, maintaining workpiece accuracy.
Electric Motors and Generators
Electric motor bearings must handle radial loads from magnetic forces while maintaining precise air gap clearances. Our bearings feature optimized internal clearances that accommodate thermal expansion during motor operation, preventing premature failure from inadequate clearance or excessive preload. They serve motors from fractional horsepower to multi-megawatt industrial drives.
Construction and Material Handling
Cranes, hoists, and conveyor systems utilize construction machinery bearings for load-bearing shafts and drive wheels. Our designs accommodate the high radial loads typical of material handling operations while resisting contamination from construction site environments. Sealed configurations extend service life in dusty, wet conditions.
Precautions
Keep Away from Children & Pets
While Water Grass Glue is non-toxic, it is not edible. Store it in a high cabinet or locked drawer to prevent accidental ingestion by children or pets.
Storage Recommendations
Store the glue in a cool, dry place away from direct sunlight. Extreme heat or moisture can shorten its shelf life—avoid storing it near aquariums or sinks where water may splash onto the container.
Surface Preparation
Before application, clean the bonding surface to remove dirt, oil, or algae (for aquarium use). For underwater application, wipe excess water from the surface to ensure the glue adheres properly.
Material Engineering and Manufacturing Process
Advanced Metallurgy
We source premium GCr15 bearing steel (equivalent to AISI 52100 or 100Cr6), containing optimized carbon and chromium content for maximum hardness and wear resistance. The steel undergoes vacuum degassing to minimize non-metallic inclusions, producing ultra-clean material that resists fatigue crack initiation. This high-quality bearing steel forms the foundation for extended operational lifespans.
Precision Heat Treatment
Our heat treatment protocols employ controlled quenching and tempering cycles that achieve uniform hardness distribution throughout bearing components. Raceways and rollers receive through-hardening to 58-64 HRC, while cage materials undergo appropriate heat treatment for their specific alloy composition. This optimized heat treatment maximizes rolling contact fatigue resistance.
Ultra-Precision Grinding
Final raceway and roller grinding operations utilize advanced centerless grinding and form grinding techniques, achieving dimensional tolerances within micrometers. Surface finish grinding produces mirror-like surfaces with Ra values below 0.2μm, minimizing friction and wear during operation. Our precision grinding technology ensures consistent bearing performance batch after batch.
Comprehensive Quality Testing
Every production batch undergoes rigorous testing including dimensional measurement, surface roughness analysis, hardness verification, and vibration testing. Selected bearings receive extended endurance testing under simulated operational conditions. This 100% quality inspection protocol ensures only bearings meeting our strict standards reach customers.
Installation and Maintenance Guidelines
Proper Mounting Procedures
Clean all bearing surfaces and shafts before installation to prevent contamination. Use appropriate mounting tools—arbor presses for small bearings, induction heaters or oil baths for thermal mounting of larger units. Never hammer directly on bearing races, as impact loading can cause internal damage invisible to external inspection.
Lubrication Requirements
Select lubricants matching operating conditions: mineral oils for moderate temperatures, synthetic lubricants for extreme temperatures or chemical environments. Grease lubrication suits sealed bearings or applications with limited relubrication access. Monitor lubricant condition regularly and establish relubrication intervals based on operating temperature and speed.
Clearance Considerations
Account for thermal expansion when selecting internal clearance classes. High-temperature operations require increased clearance (C3, C4) to prevent interference fits during thermal growth. Conversely, precision applications benefit from reduced clearance (C2) to maximize rigidity. Consult our technical team for clearance selection guidance.
Condition Monitoring
Implement vibration monitoring and temperature tracking for critical applications. Rising vibration amplitudes or operating temperatures indicate developing problems—contamination, inadequate lubrication, or bearing damage. Early detection through predictive maintenance programs prevents catastrophic failures and unplanned downtime.
Comparison with Related Bearing Types
Cylindrical vs. Spherical Roller Bearings
While spherical roller bearings accommodate misalignment through barrel-shaped rollers, cylindrical roller bearings offer higher radial load capacity and superior speed capabilities when alignment is controlled. Choose cylindrical types for applications with rigid shaft support and minimal deflection; select spherical types when shaft misalignment exceeds 0.5 degrees.
Cylindrical vs. Tapered Roller Bearings
Tapered roller bearings handle combined radial and axial loads through their angular contact geometry, whereas cylindrical roller bearings specialize in pure radial loading. Applications requiring thrust capacity (e.g., vehicle wheel hubs) favor tapered designs; applications with minimal axial loads benefit from cylindrical bearings' higher radial capacity and simpler mounting.
Cylindrical vs. Ball Bearings
Ball bearings accommodate higher speeds and combined loads but offer lower radial capacity than cylindrical roller bearings of equivalent size. Choose deep groove ball bearings for high-speed, moderate-load applications; select cylindrical roller bearings when radial loads dominate and speeds remain within bearing limits.
Frequently Asked Questions
What radial load capacity do cylindrical roller bearings offer compared to ball bearings?
Cylindrical roller bearings typically provide 30-50% higher radial load capacity than ball bearings of similar dimensions. This stems from the line contact between rollers and raceways, which distributes forces across larger surface areas compared to point contact in ball bearings. For heavy industrial applications, this increased capacity translates to smaller bearing sizes or extended service life.
Can cylindrical roller bearings handle axial loads?
Standard cylindrical roller bearings accommodate only minimal axial loads—typically 5-10% of rated radial capacity. Their roller-raceway geometry permits slight axial displacement but lacks the contact angles necessary for substantial thrust loads. For applications requiring combined loading, consider angular contact ball bearings, tapered roller bearings, or paired cylindrical bearing arrangements with thrust washers.
How do I select the appropriate internal clearance class?
Clearance selection depends on operating temperature, fit tolerances, and application requirements. Standard C0 clearance suits ambient temperature applications with moderate fits. High-temperature operations (>80°C) require increased clearance (C3, C4) to compensate for thermal expansion. Precision applications benefiting from maximum rigidity may specify reduced clearance (C2). Our technical team provides clearance calculation services for complex applications.
What maintenance intervals do these bearings require?
Maintenance intervals vary with operating conditions—speed, load, temperature, and environmental contamination levels all influence lubrication degradation rates. General guidelines suggest grease relubrication every 2,000-10,000 operating hours, with shorter intervals for high-speed or high-temperature applications. Oil-lubricated bearings require condition monitoring and filtration maintenance. Implement vibration analysis for predictive maintenance scheduling.
Are your cylindrical roller bearings compatible with automated lubrication systems?
Yes—our bearings integrate seamlessly with centralized lubrication systems common in industrial facilities. Specify appropriate groove and hole configurations during ordering to ensure lubricant reaches critical rolling contact zones. We provide technical guidance on lubricant selection, flow rates, and system design for automated lubrication applications.
What sealing options protect bearings in contaminated environments?
We offer multiple sealing solutions: open bearings for external sealing systems, contact seals for maximum protection with slight friction increase, and non-contact shields balancing protection with minimal friction. Mining, construction, and food processing applications typically require sealed configurations. Our engineering team recommends sealing strategies based on specific contamination types and severity levels.
