Tapered Roller Bearings FAG 33116

The FAG 33116 single-row tapered roller bearing, measuring 80 × 130 × 37 mm, is capable of withstanding high radial and axial loads simultaneously in mechanical engineering applications.

The 33116 tapered roller bearing is an open, single-row radial roller bearing in a standard design. FAG manufactures this rolling bearing with the key dimensions of an 80 mm bore, a 130 mm outer diameter and a 37 mm width. Due to the tapered arrangement of the rolling elements, the bearing is suitable for demanding industrial applications involving combined loads. Structurally, the bearing consists of an inner ring with a set of rollers and a separate outer ring. This split design simplifies both installation and subsequent maintenance work on shafts and gearboxes.

In which applications is the 33116 tapered roller bearing used?

Combined loads consisting of radial forces and unilateral axial forces constitute the primary area of application for the 33116 tapered roller bearing. Typical applications include gearbox shafts, axle bearings and general industrial drives. As single-row tapered roller bearings can only accommodate axial forces in one direction, they are usually fitted in a mirror-image pair with a second bearing. This arrangement results in a rigid shaft guidance system. The permissible temperature range extends from –30 to +120 degrees and covers standard operating conditions in industrial environments.

What role does the sheet steel cage play in the 33116 tapered roller bearing?

The integrated sheet steel cage guides the tapered rollers along the raceway of the inner ring and maintains the flow of lubricant. It is characterised by dimensional stability under thermal stress in the range from -30 to +120 degrees. Together with tolerance class P0 (ABEC 1 standard), the bearing ensures smooth running. During assembly, adjust the axial bearing clearance via the mating bearing. Ensure proper lubrication, as this is an open bearing without integrated seals.
