FAQ

What is the difference between CA and CC cage for 22300 spherical roller bearings?

CC uses stamped steel two-piece cage, lower cost for general heavy load. CA is solid machined brass cage, better shock resistance, widely used in vibrating screens and crushers.

What does W33 mean?

W33 means there is a circumferential grease groove and 3 lubrication holes on outer ring, convenient for re-lubrication during running.

What is C3 clearance?

C3 is larger than standard CN clearance, designed for high temperature and vibration applications, the most popular option for mining vibrating machinery.

Do you support OEM and custom packaging?

Yes, we support OEM with your own brand logo, neutral export packaging and customized marking for bulk importers and distributors.

Category Overview

Spherical Roller Bearings are double-row, self-aligning rolling bearings with barrel-shaped rollers and a spherical outer raceway. They are specially designed to accommodate heavy radial loads, impact loads, and moderate axial loads, while automatically compensating for shaft deflection and mounting misalignment.With exceptional rigidity, durability, and low maintenance requirements, they are widely used in heavy industrial machinery operating under severe conditions.

Our Series Breakdown

We offer a complete range of spherical roller bearing series to meet different load, size and application needs:

Series	Features	Typical Applications
222 Series	Compact design, medium load capacity, good self-aligning performance	General heavy machinery, reducers, fans, pumps
223 Series	Enhanced load capacity, wider cross-section, strong shock resistance	Crushers, vibrating screens, conveyors, mining equipment
230 Series	Low cross-section, high stiffness, suitable for restricted radial space	Large gearboxes, paper machines, industrial transmission
240 Series	Extra wide cross-section, ultra-heavy load capacity, long service life	Large-scale crushers, mills, metallurgical equipment
231 Series	High load, large size, good axial load resistance	Heavy reducers, rolling mills, large fans
241 Series	Super heavy-duty, large dimensions, high reliability	Metallurgical machinery, mining equipment, large crushers

Core Advantages
