Spherical Roller Bearing CA vs CC Cage Difference

2026-09-11 15:47:00

The service life of Spherical Roller Bearings mainly depends on cage structure suffixes rather than basic model numbers. Bearings with the same basic size but different CA and CC suffixes share identical mounting dimensions but completely different internal stability and shock resistance.

CC type adopts a stamped steel cage with light weight, low friction and stable temperature rise. It is cost-effective and suitable for steady-running equipment such as fans, conveyors and standard gearboxes. The open internal structure improves grease circulation for long-term continuous operation.

CA type features a one-piece solid brass cage with high rigidity and precise roller positioning. It delivers excellent shock resistance and low vibration performance, ideal for heavy‑duty machinery with fluctuating loads and frequent start‑stop operation, including crushers, rotary kilns and metallurgical roller tables.

For steady and low‑impact working conditions, CC bearings are the best cost‑effective choice. For heavy loads and slight shocks, CA solid brass cages are strongly recommended. Users must not replace CA with CC blindly, otherwise premature cage deformation and bearing failure will occur.
