What are the dimensions of this SKF 30305 J2/Q bearing?

The bearing has an inside diameter of 25 mm, an outside diameter of 62 mm, and an overall width of 18.25 mm.

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

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

What do the suffixes J2 and Q mean in the part number?

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

Are the inner and outer rings separable?

Yes, the outer ring (cup) is separable from the inner ring with roller assembly (cone), making mounting and dismounting easier.

Can this bearing handle axial loads in both directions on its own?

No, to support axial loads in both directions, it must be mounted in a mirrored arrangement with a second tapered roller bearing.

Robust load support with Skf 30305 J2/Q

Practical benefits

High combined load capacity: You accommodate heavy radial and axial loads in one direction simultaneously, supported by the tapered raceway geometry.
Low friction running operation: The optimized internal surfaces reduce running friction, keeping your equipment operating smoothly and extending service life.
Quick and separable assembly: You assemble and maintain machinery faster because the inner and outer rings separate cleanly for straightforward mounting.

In a nutshell

The right choise for

With the Skf 30305 J2/Q single-row tapered roller bearing, you reliably accommodate heavy radial loads and unidirectional axial forces simultaneously. Designed for demanding applications such as wheel hub assemblies, industrial gearboxes, and drivetrain transmissions, this bearing provides the rigid support your machinery requires. The optimized internal geometry minimizes friction and heat build-up on rotating shafts, keeping your equipment running smoothly and efficiently. Because the inner and outer rings are completely separable, you complete installation, preloading, and routine inspections quickly and without complications.

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
