Tapered Roller Bearings FAG 33118

The FAG 33118 tapered roller bearing, with dimensions of 90 × 150 × 45 mm, is designed to accommodate combined radial and single-direction axial loads in mechanical engineering applications.

The 33118 tapered roller bearing is a single-row roller bearing from FAG, designed to simultaneously accommodate high radial forces and single-direction axial forces. Due to the tapered design of the rollers and raceways, the contact lines intersect on the bearing axis, which promotes slip-free operation. With a bore of 90 mm, an outside diameter of 150 mm and a width of 45 mm, the assembly provides a stable basis for mechanical designs.

In which configurations does the 33118 tapered roller bearing accommodate axial loads?

Due to their design, tapered roller bearings can only accommodate axial forces in one direction and are therefore usually mounted in pairs in conjunction with a second bearing. A typical installation is in an O or X arrangement, which results in a guided shaft bearing arrangement and allows alternating axial forces to be supported. The coordinated roller geometry copes with high loads in continuously operated shaft bearing arrangements.

How is the separable tapered roller bearing 33118 fitted and adjusted?

The complete tapered roller bearing has a separable design: the inner ring, including the roller cage, and the outer ring can be fitted separately, which makes handling during assembly easier. The integrated sheet steel cage keeps the rolling elements spaced apart and is suitable for a temperature range of -30 to +120 degrees. Manufactured to the standard tolerance class P0/PN (corresponding to ABEC 1), the bearing is suitable for conventional bearing seats. The operating clearance is only adjusted during installation by axially aligning the bearing against the mating bearing.
