What are the dimensions of this SKF tapered roller bearing?

This bearing features an inside diameter of 30 mm, an outside diameter of 72 mm, and a total width of 20.75 mm.

What types of loads can this single-row bearing handle?

It is designed to accommodate combined radial and axial loads, supporting axial forces in one direction.

What is the advantage of the 28.8° contact angle?

The steep 28.8° contact angle provides a significantly higher axial load carrying capacity.

Are the inner and outer rings separable?

Yes, the inner ring with roller assembly and the outer ring are separable and can be mounted individually.

What does the suffix J2/Q indicate?

J2 indicates a pressed steel cage and Q signifies optimized internal geometry and surface finish.

Reliable capacity for heavy combinations

Practical benefits

High combined load capacity: With a 28.8° contact angle, you reliably support heavy simultaneous radial and axial forces in demanding setups.
Low friction smooth running: The optimized internal geometry of the Skf tapered roller bearing reduces friction to extend operating life.
Quick and easy installation: Because the inner and outer rings are separable, you mount and maintain your mechanical assemblies with ease.

In a nutshell

The right choise for

With the Skf 31306 J2/Q single-row tapered roller bearing, you easily handle heavy combined radial and axial loads. Featuring a steep 28.8° contact angle, it delivers superior axial load capacity in one direction, making it ideal for the maintenance of industrial gearboxes, drive shafts, pumps, and differential assemblies. The optimized internal geometry and refined surface structure significantly reduce rotational friction, ensuring smooth operation and extended machinery service life. Because the inner ring with its steel cage and the outer ring are completely separable, you can install components swiftly and adjust internal clearance or preload with extreme precision.

Outer diameter: 72 mm
Width: 20,75 mm

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
