What are the dimensions of this tapered roller bearing?

The SKF 30306 J2/Q has an inside diameter of 30 mm, an outside diameter of 72 mm, and a total width of 20.75 mm.

What loads can this SKF bearing accommodate?

This single-row tapered roller bearing is designed for combined loads, handling simultaneous radial and axial forces in one direction.

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

Yes, the parts are separable and interchangeable. You can mount the inner ring assembly independently from the outer cup.

What is the contact angle of this model?

This bearing features a contact angle of 11.9°, providing effective axial load support.

How do you achieve a rigid bearing arrangement?

Mount a second single-row tapered roller bearing against the first and apply a preload to create a rigid setup.

Reliable load performance with Skf

Practical benefits

High combined load capacity: You easily support heavy simultaneous radial and axial loads in rotating machinery applications.
Simple mounting and maintenance: Because the inner and outer rings are separable, you complete installation and servicing quickly.
Low friction for longevity: The optimized roller and raceway geometry minimizes friction so you achieve extended component service life.

In a nutshell

The right choise for

With the Skf 30306 J2/Q single-row tapered roller bearing, you ensure dependable performance and precise alignment in industrial gearboxes, drive systems, and vehicle wheel hubs. It simultaneously accommodates heavy radial and unidirectional axial loads thanks to its 11.9° contact angle. Because the inner ring assembly and outer ring are separable and interchangeable, you complete mounting, dismounting, and routine servicing quickly and accurately. The optimized raceway geometry minimizes rotational friction and heat build-up, significantly extending component service life. By mounting a second single-row bearing in opposition and setting the correct preload, you easily achieve a rigid, highly stable shaft arrangement.

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
