Features and benefits

High load carrying capacity 

Because of their second row of rollers, double row cylindrical roller bearings are suitable for heavy radial loads.

Low friction (Roller end / flange contact area) 

The open flange design, together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity.

Long service life 

The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
