CA Series Spherical Roller Bearings

Product Overview

The CA Series Spherical Roller Bearings are engineered to withstand extremely high radial loads and moderate axial loads, making them ideal for demanding heavy-duty industrial applications. Featuring a solid brass cage design, these bearings provide excellent guidance stability, impact resistance, and reduced friction under severe working conditions.

Specifically optimized for high-efficiency impact crushers used in secondary and tertiary fine crushing processes, CA series bearings deliver outstanding reliability and long service life in high-impact environments. Their robust construction ensures consistent performance even under continuous shock loads and heavy vibration.

Manufactured from high-purity vacuum-degassed bearing steel, and treated with precision salt bath heat treatment for both rings and rollers, the CA series maintains superior structural strength and wear resistance. The hardness difference is controlled within 1 HRC, which is 30% stricter than GB/T 34891-2017 standards, ensuring exceptional quality consistency and operational stability.
