23156 CCK/C3W33

The 23156 CCK/C3W33 spherical roller bearing is explicitly designed for applications where high load capacity and reliable operation are paramount, even in challenging environments. As a double-row component, it is inherently capable of handling very heavy radial loads and substantial bidirectional axial loads, making it a mainstay in demanding equipment like large fans, conveyors, crushers, and gearboxes. A critical feature is its self-aligning ability, which effortlessly compensates for any shaft misalignment or deflection that can occur due to mounting errors or frame distortions under heavy loads. This functionality prevents damaging stress peaks and ensures the load is distributed evenly across the rollers, a key factor in achieving the bearing's advertised long service life and minimizing costly, unplanned downtime.

Key technical specifications of the 23156 CCK/C3W33 contribute to its robust performance. The tapered bore (K), with a 1:12 taper, facilitates straightforward mounting and removal using adapter or withdrawal sleeves, providing flexibility during installation and maintenance. The design incorporates a sheet steel cage (CC) known for its durability and optimized internal geometry, ensuring smooth roller guidance. Furthermore, the C3 internal radial clearance is greater than normal, making the bearing ideal for machinery operating under conditions where heat generation is expected, accommodating thermal expansion effectively. Finally, the W33 feature-annular groove and three lubrication holes in the outer ring-simplifies relubrication, supporting continuous operation and extending the time between maintenance cycles for maximum productivity.
