What are the dimensions of this SKF bearing?

The bearing has an inside diameter of 60 mm, an outside diameter of 130 mm, and a width of 33.5 mm (specified as 33.37 mm).

What types of loads can the SKF 31312 J2/Q accommodate?

This single-row tapered roller bearing accommodates combined radial loads and heavy axial loads in one direction due to its 28.8° contact angle.

What do the suffixes J2 and Q indicate?

J2 indicates a pressed steel window-type cage, while Q designates an optimized internal geometry and surface finish.

Can the inner and outer rings be mounted separately?

Yes, the inner ring with roller assembly and outer ring are separable and interchangeable, making mounting and maintenance easier.

Reliable power transmission with Skf

Practical benefits

High combined load capacity: You accommodate heavy simultaneous radial and axial loads thanks to the steep 28.8° contact angle.
Smooth and efficient rotation: The optimized roller profile evenly distributes contact stress to reduce friction and heat during operation.
Simple and precise mounting: Because the inner and outer rings are separable, you can mount components easily and adjust clearance accurately.

In a nutshell

The right choise for

With the Skf 31312 J2/Q single-row tapered roller bearing, you ensure dependable power transmission even under demanding operational conditions. Thanks to its steep 28.8° contact angle, you easily accommodate heavy combined radial loads and high unidirectional axial thrust forces. The optimized internal geometry and roller profile evenly distribute contact stress, minimizing friction and heat build-up during intense rotation. This makes it a solid choice for heavy-duty industrial gearboxes, vehicle wheel hubs, and drivelines. Because the inner and outer rings are separable, you can mount components smoothly and adjust clearance accurately, achieving high rigidity and precise shaft guidance across your machinery.

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
