22317 CAW33C3 SING ISB spherical roller bearing

22317 CAW33C3 SING ISB Spherical Roller Bearing – For Very High Loads and Elevated Temperature Operation

Product Description

22317 CAW33C3 SING ISB is a double-row spherical roller bearing designed for operation under very high radial loads and axial loads acting in both directions. The spherical roller design effectively compensates for shaft and housing misalignment, as well as shaft deflection during operation, significantly increasing the durability and reliability of the entire drive system.

The CAW33C3 version features a machined cage (CA type), a lubrication groove with lubrication holes in the outer ring (W33), and increased internal clearance C3, intended for operation at elevated temperatures or higher rotational speeds. The SING designation indicates single commercial packaging.

Applications

• Industrial gearboxes
• Crushers and vibrating screens
• Construction and agricultural machinery
• Industrial fans and blowers
• Heavy-duty drives operating under high loads
