22312 CCW33C3 ISB SING spherical roller bearing

22312 CCW33C3 SING ISB Spherical Roller Bearing – For Very High Loads and Elevated Temperature Operation

Product Description

22312 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. The spherical roller design allows compensation of shaft and housing misalignment, as well as shaft deflection during operation, significantly increasing durability and reliability in demanding industrial applications.

The CCW33C3 version features a steel cage (CC), 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
• Fans and blowers
• Conveyor systems
• Construction and agricultural machinery
• Drive systems operating under heavy loads and harsh environmental conditions
