FAQ

What is the difference between 231 series and 23000 series spherical roller bearings?

23000 series is narrow cross-section for limited mounting space. 231 series is medium wide section with higher load capacity, suitable for heavy shock load such as mining crushers.

What does K suffix stand for on 231 bearings?

K means 1:12 tapered inner bore, mounted with adapter sleeve, convenient for installation and disassembly.

What is W33 for 231 spherical roller bearing?

W33 stands for circumferential grease groove and 3 lubrication holes on outer ring, supports re-lubrication during continuous heavy operation.

What is the difference between CA and CC cage?

CC: stamped steel cage, economical for general heavy load. CA: machined brass cage, better shock resistance for mining and cement industry.

Do you support OEM and custom export packaging?

Yes, we support OEM with YJZY brand logo, neutral export packaging and customized marking for bulk importers and machinery 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.
