Tapered Roller Bearings FAG 32028 -X

The FAG 32028-X tapered roller bearing is designed for combined loads consisting of radial and single-direction axial forces, with dimensions of 140 × 210 × 45 mm.

The FAG 32028 -X tapered roller bearing is a single-row roller bearing in standard design. It accommodates both radial forces and axial loads from one direction simultaneously. The tapered raceways allow the tapered rolling elements to roll along them. The complete bearing consists of the inner ring with a roller cage and the separate outer ring. This allows the two bearing components to be fitted and aligned separately from one another.

How is the 32028 -X tapered roller bearing used in operation?

In mechanical designs and shaft mountings, a single single-row tapered roller bearing, by its very design, can only accommodate axial forces in one direction. For this reason, in practice, users usually fit a second bearing in a mirror-image configuration on the shaft as a counter-bearing. This paired arrangement guides the shaft axially in both directions and allows for the precise adjustment of the operating clearance or a defined preload.

What is the function of the sheet steel cage in the bearing?

The integrated sheet steel cage maintains an even spacing between the tapered rollers and prevents direct contact between the rolling elements. This reduces friction and heat build-up during rotational movement. The component is designed for a temperature range of –30 to +120 degrees. With a tolerance class of P0/PN or ABEC 1, the bearing complies with the standardised specifications for dimensional accuracy and concentricity in industrial applications.
