Key Performance Features

01. High-Quality Bearing Steel & Heat Treatment

Manufactured from chrome steel (GCr15 / SAE 52100) with advanced heat treatment, the 6008-2RS offers consistent hardness and dimensional stability. The robust construction withstands typical operating stresses, providing long-term reliability in continuous-duty applications.

02. Double-Lip Contact Seal Protection

The 6008-2RS is equipped with non-removable rubber seals (NBR) that provide excellent resistance to dust, moisture, and light splash. The seal lips maintain constant contact with the inner ring land, effectively retaining grease and extending service life in dirty or humid environments without requiring re-lubrication.

03. Optimized Internal Geometry

Engineered with a precision-ground raceway and a carefully selected ball complement, this bearing minimizes frictional torque while ensuring smooth, quiet operation. The internal design is optimized for even load distribution, enhancing fatigue life under moderate radial and axial loads.
