Tapered Roller Bearings FAG 30217

The FAG 30217 single-row tapered roller bearing, measuring 85 × 150 × 30.5 mm, can accommodate both high radial forces and unilateral axial loads simultaneously.

The FAG 30217 tapered roller bearing is an open, single-row roller bearing designed for demanding industrial applications. Owing to the tapered arrangement of the rolling elements, the bearing is particularly suitable for withstanding combined loads from both the radial and axial directions. With an inner diameter of 85 mm, an outer diameter of 150 mm and a width of 30.5 mm, this model corresponds to the standard design. You will receive a complete rolling bearing, comprising an inner ring with a set of rollers and the corresponding outer ring.

What are the practical applications of the 30217 tapered roller bearing?

Designs in mechanical engineering and drive technology frequently utilise this type of bearing where shafts need to be guided and rigid mounting is required. Typical applications include gearbox designs and shaft mountings subject to combined loads. As a single tapered roller bearing can, by design, only accommodate axial forces in one direction, it is usually fitted in pairs in conjunction with a second bearing positioned in a mirror-image configuration. This enables stable guidance of the shaft under varying load directions.

What role do the sheet steel cage and tolerance class play in the 30217 tapered roller bearing?

This tapered roller bearing is fitted with a sheet steel cage, which guides the rollers evenly along the raceway and enables operation within a temperature range of -30 to +120 degrees. The bearing is manufactured to the standard tolerance P0/PN (corresponding to ABEC 1), which meets the standardised accuracy requirements of general mechanical engineering. As the inner and outer rings are not permanently joined, both components can be fitted separately, which simplifies handling during installation and maintenance.
