22317 CCW33C3 SING ISB spherical roller bearing

22317 CCW33C3 SING ISB Spherical Roller Bearing – For Very High Loads and Elevated Temperature Operation

Product Description

22317 CCW33C3 SING ISB is a double-row spherical roller bearing designed for operation under very high radial loads and axial loads acting in both directions. Thanks to its spherical roller design, it effectively compensates for shaft and housing misalignment as well as shaft deflection during operation, significantly increasing the durability and reliability of the entire system.

The CCW33C3 version features a steel cage (CC), a lubrication groove with lubrication holes in the outer ring (W33) for efficient lubrication, and increased internal clearance C3, suitable for operation at elevated temperatures or higher rotational speeds. The SING designation indicates single commercial packaging.

Applications

• Industrial gearboxes
• Crushers and vibrating screens
• Industrial fans and blowers
• Construction and agricultural machinery
• Drive systems operating under heavy loads and harsh environmental conditions
