Reliable load handling for combined forces

Practical benefits

High combined load capacity: With a 13° contact angle, you efficiently absorb simultaneous radial and single-direction axial forces in demanding mechanical setups.
Quick and easy installation: The separable design of the inner and outer rings lets you mount and maintain the bearing with minimal effort.
Reduced friction during operation: Optimized contact surfaces lower running temperatures and friction, giving you smoother rotation and extended equipment service life.

In a nutshell

The right choise for

With the Skf 30308 J2/Q single-row tapered roller bearing, you achieve rigid and dependable shaft guidance under demanding operating conditions. Thanks to its 13° contact angle, it effortlessly handles high simultaneous radial loads and single-direction axial thrust in industrial gearboxes, vehicle wheel hubs, and transmissions. The optimized surface finish noticeably reduces friction and heat generation, delivering quieter rotation and extending equipment service life. Featuring separable inner and outer rings with a pressed steel cage, this 40 x 90 x 25.25 mm bearing allows for quick, accurate mounting and straightforward maintenance.

Product description

Single row tapered roller bearings are designed to accommodate combined radial and axial loads and provide low friction during operation. The inner ring, with rollers and cage, can be mounted separately from the outer ring. These separable and interchangeable components facilitate mounting, dismounting and maintenance. By mounting one single row tapered roller bearing against another and applying a preload, a rigid bearing application can be achieved.

Avantages

High radial and axial load carrying capacity
Accommodate axial loads in one direction
Low friction and long service life
Separable and interchangeable components
