The cast iron extended flange bearing unit stands as a foundational mechanical component engineered for demanding rotational support. Crafted strictly to JIS standard specifications, this assembly unites a precision-ground insert bearing with an extended inner ring, all encased within a dense, vibration-absorbing cast iron housing. The moment you handle the unit, the substantial weight and smooth, powder-coated finish of the enclosure convey its industrial-grade durability. Featuring a secure set screw locking mechanism and a geometrically optimized 2-hole flange profile, this assembly resolves critical spatial constraints in modern equipment design while maintaining exceptional structural rigidity.
Whether managing continuous directional loads or enduring alternating rotation cycles, this flange-mounted unit delivers unwavering stability. The extended inner architecture inherently compensates for minor shaft misalignments, drastically reducing the friction and heat typically generated by imperfect mounting surfaces. Designed specifically for wall or frame attachment, the housing provides a highly dependable solution for facility managers and procurement teams aiming to minimize equipment downtime across manufacturing, material processing, and agricultural sectors.
Distinctive Features and Advantages
Advanced Contamination Protection System
The cast iron flange bearing unit incorporates a sophisticated dual-seal architecture that forms a formidable physical barrier against harsh environmental elements. An inner synthetic rubber seal physically sweeps the rotating shaft, while a precision-stamped sheet steel slinger acts as the primary deflector. This multi-layered defense mechanism actively repels airborne particulate matter, metallic shavings, and moisture infiltration, ensuring the internal raceways remain pristine even in heavily polluted processing facilities.
Superior Thermal and Velocity Performance
Built for intense operational cycles, this flange ball bearing unit excels under elevated temperatures and rapid rotational demands. The internal geometry is meticulously calibrated to dissipate friction-induced heat, maintaining dimensional stability across fluctuating thermal conditions. The precision-balanced rotating elements emit a steady, quiet hum during operation, safely supporting rotation speeds up to 5,850 r/min without compromising the structural integrity of the lubrication film.
Robust Load-Bearing Capacity
Forged from premium bearing steel and cradled in a reinforced cast iron body, this oval flange bearing unit thrives under substantial radial forces. The housing's thick-walled construction actively absorbs operational shocks, distributing mechanical stress evenly across the rolling elements. This calculated load distribution prevents localized surface fatigue, dramatically extending the service life of critical conveyor drives and industrial fluid pumps.
Misalignment Tolerance Capability
Installation imperfections are effortlessly managed by the extended inner bearing design, which allows for moderate static misalignment angles. This flange mounted bearing accommodates minor frame deflections that occur under heavy operational loads. Assembly teams benefit from reduced precision requirements during the initial bolting phase, translating to faster installation times and fewer alignment-related maintenance callbacks.
Lifetime Lubrication System
Delivered pre-packed with a specialized, temperature-resistant grease, the unit offers a tactile, smooth rotation right out of the box. For standard operational profiles, the factory lubrication lasts the entire lifecycle of the component. When pushed beyond normal parameters, the strategically placed, flush-mounted zerk fitting allows maintenance crews to easily inject supplementary grease, purging old lubricants and extending the operational timeline.
The streamlined 2-hole flange configuration maximizes functional density in space-restricted machinery. Beyond its spatial efficiency, this extended inner bearing unit is engineered with standardized external dimensions and accompanied by a comprehensive cross-reference guide. This guarantees exact interchangeability with mainstream international brands, allowing facility operators to seamlessly upgrade their existing equipment without incurring costly frame modifications or re-engineering expenses.
Materials and Manufacturing Process
Component Materials & Quality Assurance
The core insert and rolling elements are machined from hardened bearing steel, chosen for its exceptional wear resistance and fatigue limit. The surrounding cast iron housing delivers superior acoustic dampening, neutralizing operational vibrations before they reach the machine frame. Backed by strict ISO 9001 quality management protocols, every production batch is fully traceable. Procurement teams can request complete Certificates of Conformity (CoC) and detailed material analysis reports, guaranteeing 100% industrial-grade compliance for critical infrastructure projects.
Precision Manufacturing & Deep Customization
The manufacturing journey involves precise heat treatment cycles that create a hardened outer shell while retaining a tough, ductile core within the steel components. Advanced grinding processes achieve exacting dimensional tolerances for frictionless rotation. Furthermore, each flange bearing housing can be tailored through our comprehensive OEM and ODM customization services. For extreme thermal environments or highly corrosive chemical plants, the housing material, internal clearances, and sealing structures can be specifically engineered and modified to match exact operational requirements.

Installation and Operational Guidelines
Pre-Installation Preparation
Wipe the shaft clean of any protective shipping oils, feeling for any microscopic burrs or surface scoring. It is critical to verify the shaft diameter strictly adheres to the h6 tolerance specification to achieve the intended interference fit. Visually inspect the housing and seals to confirm all components are present and the unit arrived in pristine condition.
Mounting Procedure
Press the flange bearing unit against the mounting plate, aligning the bolt holes with the frame attachment points. Thread the bolts and tighten them in a progressive, alternating cross-pattern to prevent housing distortion and ensure even load distribution. Once positioned on the shaft, secure the set screws. The audible bite of the hardened screws into the shaft ensures a slip-free connection that prevents shaft damage.
Alignment Verification
While the spherical outer ring provides natural misalignment compensation, utilizing a dial indicator to achieve near-perfect initial alignment pays dividends in longevity. Proper centering minimizes internal friction, allowing the rolling elements to glide effortlessly along their raceways and maximizing operational efficiency.
Operating Environment Considerations
Monitor ambient temperatures to ensure they remain within the lubricant's effective range, preserving both grease properties and material integrity. While the dual-seal system provides excellent contamination protection, avoid prolonged exposure to highly concentrated corrosive chemicals or excessive moisture that could eventually degrade the synthetic rubber seal lip over years of continuous exposure.
Load and Speed Compliance
Strict adherence to mechanical limits is non-negotiable to prevent premature failure. The assembly must operate within the specified basic dynamic load rating of 14 kN and basic static load rating of 7.8 kN. Do not exceed the limiting speed of 5,850 r/min, as excessive rotational velocities will result in rapid lubricant degradation, excessive thermal expansion, and accelerated component wear.
