Tapered Roller Bearings FAG 32303

The single-row tapered roller bearing 32303 from FAG Wälzlager, with dimensions of 17 × 47 × 20.25 mm, can accommodate high radial and single-direction axial loads.

The 32303 tapered roller bearing from FAG Wälzlager is a single-row roller bearing in a standard design for industrial and workshop applications. With a bore of 17 mm, an outer diameter of 47 mm and a width of 20.25 mm, this component is suitable for compact shaft mountings. Thanks to the tapered arrangement of the rollers, the bearing simultaneously transmits radial loads and axial forces from one direction. Manufactured to tolerance class P0 or ABEC 1, it ensures precise concentricity.

In which applications is the 32303 tapered roller bearing used?

The 32303 tapered roller bearing is particularly suitable for bearing arrangements where high radial forces coincide with axial forces acting in one direction. Typical applications can be found in general mechanical engineering on rotating shafts. As single-row tapered roller bearings can only accommodate axial forces from one side, they are usually arranged in pairs in a mirror-image configuration in designs. This method enables play-free guidance of rotating shafts under various load conditions.

What are the distinctive features of the sheet steel cage and the temperature range?

This complete tapered roller bearing is fitted with a sheet steel cage, which guides the tapered rolling elements and maintains a constant spacing between them. The permissible temperature range extends from –30 to +120 degrees Celsius, allowing for use under varying thermal environmental conditions. When designing the bearing, it is advisable to select a lubricant suitable for this temperature range. Furthermore, the bearing can be disassembled: the inner ring with the set of rollers and the outer ring can be fitted separately, which facilitates installation in housings and onto shafts.
