Tapered Roller Bearings FAG 33115

With its dimensions of 75 × 125 × 37 mm, the FAG 33115 tapered roller bearing is capable of withstanding high radial loads as well as axial loads on one side in mechanical engineering applications.

The single-row tapered roller bearing 33115 from FAG Wälzlager consists of an inner ring with a roller cage and a separate outer ring. Thanks to the angled tapered rollers, this bearing is suitable for combined loads. The sheet steel cage guides the rollers evenly along the hardened raceways. With a bore of 75 mm, an outside diameter of 125 mm and a width of 37 mm, this bearing is suitable for a wide range of applications in industrial mechanical engineering.

What is the 33115 tapered roller bearing suitable for?

Bearing arrangements subject to combined radial and axial loads, as well as rigid shaft guides, constitute the typical field of application for the 33115 tapered roller bearing. As a single bearing can only accommodate axial forces from one direction, in practice they are usually fitted in pairs in an X or O configuration with a mirror-image mating bearing. This arrangement results in a rigid bearing arrangement with precise guidance. Design engineers prefer to use this type of bearing where shafts are subjected to combined angular loads.

What should be borne in mind when fitting the separable bearing?

The complete tapered roller bearing is not self-retaining in design. You can fit the inner ring, together with the set of rollers, separately from the outer bearing shell, which makes it easier to press them into housings and onto shafts. As this bearing is supplied open from the factory, you must provide a suitable seal within the system. The permissible temperature range is from -30 to +120 degrees. Tolerance class P0 (corresponding to PN or ABEC 1) defines the standard for dimensional and concentricity characteristics in accordance with the relevant standards.
