What are the dimensions of this bearing?

This bearing has a 17 mm bore diameter, a 47 mm outside diameter, and an overall width of 15.25 mm.

What types of loads can the SKF 30303 J2 accommodate?

It is designed for combined loads: simultaneous radial loads and axial loads acting in one direction.

Are the inner and outer rings separable?

Yes, the inner ring with cage and rollers can be separated from the outer ring, facilitating easy mounting and maintenance.

Can this bearing support axial loads in both directions?

No, a single row tapered roller bearing supports axial loads in one direction only. For bidirectional loads, use two bearings opposed.

Smooth rotation with Skf

Practical benefits

High combined load support: You accommodate heavy radial and axial forces simultaneously in demanding machinery applications.
Reduced friction in operation: The optimized roller geometry minimizes running friction, keeping heat generation low and extending overall service life.
Simple mounting and maintenance: With separable inner and outer rings, you assemble, align, and service your equipment with minimal effort.

In a nutshell

The right choise for

Keep your heavily loaded rotating assemblies running smoothly and accurately with the Skf 30303 J2 single row tapered roller bearing. Sized at 17 x 47 x 15.25 mm with a 10.8° contact angle, this bearing reliably accommodates simultaneous high radial and single-direction axial loads. Its optimized design significantly reduces friction and heat generation, protecting gearboxes, drive shafts, and mechanical assemblies from premature wear while extending service life. Because the inner ring with cage and outer ring are completely separable, you can mount, align, and service your equipment quickly and with maximum precision.

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
