Core Features & Advantages
1. Self-Aligning Performance
The double-row spherical roller structure with inclined inner raceways delivers automatic self-alignment. It compensates for shaft misalignment and deflection without raising friction or operating temperature, ideal for installations with mounting errors or variable load conditions.
2. Ultra-High Load Capacity
This bearing supports heavy radial loads and bidirectional axial loads at the same time. With a 1413 kN dynamic load rating and 2500 kN static load rating, it withstands extreme stress in heavy industrial settings, meeting the bulk supply needs of global industrial buyers.
3. Low Friction & Stable Operation
The CC pressed steel cage minimizes sliding and rolling friction losses. This reduces heat generation, lowers operating temperatures, boosts operational stability and extends service life, cutting maintenance costs for end users.
4. Wide Temperature Adaptability
It operates stably in a temperature range of -30°C to 200°C, suitable for outdoor and high-heat industrial environments without performance degradation.
5. W33 Relubrication Design
The outer ring’s lubrication groove and three holes simplify routine maintenance. It ensures consistent lubrication flow, prolonging bearing life in continuous-operation equipment.
6. Shock & Vibration Resistance
The robust, solid construction resists shock loads and high vibration, making it perfect for vibrating screens, crushers and other heavy-duty machinery. As a leading
bearing exporter, E-Asia ensures this model meets global industrial quality standards.

FAQ
Q1: What is the difference between 23960 CC/W33 and 23960 CC/C3W33?
A: The core difference is radial internal clearance. CC/W33 uses CN (normal) clearance, while CC/C3W33 uses C3 (larger than normal) clearance. C3 clearance is recommended for high-temperature applications or tight interference fits.
Q2: What is the operating temperature range of this bearing?
A: It operates stably between -30°C and 200°C. Special lubricants are required for temperatures outside this range.
Q3: Does this bearing need regular relubrication?
A: Yes. The W33 design is built for relubrication. Regular grease replenishment based on operating hours extends service life, and the lubrication holes make maintenance quick.
Q4: Can this bearing handle high-vibration environments?
A: Yes. Its robust structure and self-aligning design absorb vibration and shaft deflection, making it suitable for vibrating screens, mining crushers and similar high-shock equipment.
Q5: What is the difference between cylindrical bore and tapered bore versions?
A: The standard cylindrical bore mounts directly on smooth shafts. The tapered bore (CCK/W33) uses adapter sleeves for easier installation and removal, ideal for maintenance-heavy sites.
