Tapered Roller Bearings FAG 31319

The FAG 31319 single-row tapered roller bearing, with dimensions of 95 × 200 × 49.5 mm, is designed to withstand high radial and unilateral axial loads in mechanical engineering applications.

The 31319 tapered roller bearing is a single-row rolling bearing manufactured by FAG, designed for demanding combined loads. With a bore of 95 mm, an outside diameter of 200 mm and a width of 49.5 mm, this tapered roller bearing meets the key requirements of heavy-duty industrial drives. Thanks to its tapered rollers, the bearing transmits high radial and axial loads simultaneously in one direction. Designs therefore benefit from a standard version that is easy to install for use in gearboxes and guide systems.

What is the 31319 tapered roller bearing suitable for in industrial applications?

This rolling bearing is suitable for designs in which high radial forces are combined with axial forces acting in one direction. Typical applications can be found in general mechanical engineering, in industrial gearboxes and in heavy-duty conveyor and drive systems. As single-row tapered roller bearings, by their design, can only support axial forces in one direction, engineers often fit a second bearing in a mirror-image arrangement on the shaft. This mirror-image arrangement enables precise axial guidance in both directions of rotation and stabilises the rotating shaft when subjected to high forces.

What is the significance of the tolerance class and the sheet steel cage in the 31319 tapered roller bearing?

The bearing is manufactured to the standard tolerance class P0 (equivalent to ABEC 1), which meets common fit requirements in industrial applications. A robust sheet steel cage guides the rolling elements precisely along the raceways and supports the permissible temperature range of -30 to +120 degrees Celsius. As the outer ring and inner ring are supplied separately from the roller cage, the component is easy to assemble and can then be precisely adjusted to the required operating clearance. Check the lubrication beforehand to ensure low-friction operation.
