Tapered Roller Bearings SKF 32004 X

The SKF 32004 X tapered roller bearing, measuring 20x42x15 mm, accommodates combined radial and axial loads in mechanical guides.

This single-row tapered roller bearing 32004 X is manufactured by SKF and is designed as a complete rolling bearing. The design consists of an inner ring with a set of rollers and the corresponding outer ring. Due to the line contact of the tapered rolling elements, the component is suitable for applications involving simultaneous radial and axial loads. The bearing is designed to the Explorer performance class and covers a temperature range from -30 to +120 degrees.

In what configuration does the 32004 X tapered roller bearing accommodate radial and axial forces?

Due to its design as a single-row tapered roller bearing, it can only support axial forces in one direction. For this reason, in practice they are usually fitted in pairs, with a second tapered roller bearing positioned in a mirror-image orientation to act as a counter-guide. As the inner ring with roller cage and the outer ring are supplied separately, both components can be fitted onto the shaft and housing in succession.

What is the function of tolerance class P0 and the sheet steel cage in the 32004 X tapered roller bearing?

The bearing is manufactured to the standard tolerance class P0 (PN or ABEC 1), which is designed to meet common industrial accuracy requirements. The integrated sheet steel cage guides the rolling elements at a uniform distance along the inner ring raceway. As the design is open, sealing against dirt and lubricant loss is provided by the surrounding machine housing.
