23218 CC/C3W33

The 23218 CC/C3W33 spherical roller bearing is engineered to deliver exceptional reliability and performance under highly demanding heavy-load industrial environments. Featuring a standard 90mm bore and a robust 160mm outer diameter, this 23218 CC/C3W33 unit utilizes a specialized "CC" design, which includes flangeless inner rings and symmetrical rollers guided by a stamped steel cage to optimize internal stress distribution and significantly lower operating temperatures. To ensure continuous operation in heavy machinery like vibratory screens, gearboxes, and crushers, the 23218 CC/C3W33 is manufactured with a C3 radial internal clearance that effectively counteracts thermal expansion during continuous high-speed rotation. Additionally, the integration of the W33 lubrication feature-consisting of a circumferential oil groove and three lubrication holes in the outer ring-simplifies relubrication maintenance, allowing this high-capacity bearing to smoothly accommodate structural shaft deflections and angular misalignment without sacrificing its long-term service life.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
