Tapered Roller Bearings SKF 33113

The single-row SKF 33113 tapered roller bearing, with dimensions of 65 × 110 × 34 mm, is designed to withstand high radial and unilateral axial loads in machinery and gearbox construction.

The SKF 33113 tapered roller bearing is a separable, single-row rolling bearing to standard tolerance P0/PN or ABEC 1. It consists of an inner ring with a roller cage and a separate outer ring. Due to the tapered inclination of the raceways, this roller bearing transmits simultaneously acting radial and axial forces. The design as a complete bearing in the SKF Explorer performance class supports demanding industrial applications with optimised running characteristics.

What is the 33113 tapered roller bearing suitable for?

Design engineers and maintenance personnel primarily use the 33113 tapered roller bearing in applications where high radial forces and unidirectional axial forces occur simultaneously. Typical applications include gearboxes and shaft mountings subject to combined loads. As a single tapered roller bearing can only accommodate axial loads in one direction, it is usually fitted in pairs in an X or O configuration against a second bearing during operation. This allows the axial clearance to be precisely adjusted.

What distinguishes the Explorer version with a sheet steel cage?

This model belongs to the SKF Explorer category and is characterised by optimised materials and refined surfaces. The integrated sheet steel cage guides the tapered rollers evenly and withstands mechanical stresses during operation. The permissible temperature range extends from –30 to +120 degrees Celsius, making the bearing suitable for a wide range of thermal conditions. The fact that it can be dismantled also facilitates the separate mounting of the inner and outer rings onto the housing and shaft.
