22217 CCKW33 C3 SING ISB Spherical Roller Bearing – For Very High Loads and Harsh Operating Conditions
Product Description
22217 CCKW33 C3 SING ISB is a double-row spherical roller bearing designed to operate under very high radial loads and axial loads acting in both directions. The spherical roller design effectively compensates for shaft misalignment and shaft deflection, significantly increasing durability and reliability in demanding industrial applications.
The CCKW33 version features a steel cage (CC), a tapered bore (K), and a lubrication groove with lubrication holes in the outer ring (W33), ensuring efficient and even grease distribution. The C3 internal clearance allows operation under 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
- Applications with heavy loads and variable operating conditions
