What loads can the SKF 30312 J2/Q accommodate?

This single-row tapered roller bearing supports combined radial and axial loads in one direction with a 13° contact angle.

Can the inner ring be mounted separately from the outer ring?

Yes, the inner ring with roller assembly and cage is separable from the outer ring, simplifying mounting and maintenance.

What do the suffixes J2 and Q indicate?

J2 indicates a pressed steel cage. Q denotes optimized internal geometry and improved surface finish for lower friction.

Is this bearing suitable for preloaded arrangements?

Yes, by mounting two single-row bearings against each other, you can achieve an accurately adjusted and rigid assembly.

Robust load capacity with Skf 30312 J2/Q

Practical benefits

High combined load capacity: You support high radial and axial loads simultaneously in a single direction with exceptional reliability.
Reduced friction in operation: The optimized raceway geometry minimizes frictional heat to provide smooth running and extended service life.
Easy mounting and maintenance: With separable inner and outer rings, you install, inspect, and maintain your machinery with complete ease.

In a nutshell

The right choise for

With the Skf 30312 J2/Q single-row tapered roller bearing, you ensure reliable operation in heavy industrial machinery, gearboxes, and drivetrain assemblies. Featuring an inside diameter of 60 mm, an outside diameter of 130 mm, and a width of 33.5 mm, it is built to support high radial loads and single-direction axial thrust simultaneously with a 13° contact angle. The optimized raceway geometry and pressed steel cage reduce operational friction and heat generation, delivering smooth and quiet running. Thanks to the separable inner and outer rings, mounting, setting an accurate preload, and performing routine maintenance are fast and efficient.

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
