Tapered Roller Bearings FAG 33018

The FAG 33018 tapered roller bearing, measuring 90 × 140 × 39 mm, accommodates combined radial and single-direction axial loads in industrial applications.

The 33018 tapered roller bearing is an open, single-row roller bearing in a standard design. FAG Rolling Bearings manufactures this complete component with tapered rolling elements designed to transmit both radial and axial forces simultaneously. Thanks to the line contact between the tapered rollers and the raceways, this design offers high rigidity during operation. With a bore of 90 mm and an outside diameter of 140 mm, the unit is suitable for demanding shaft mountings.

What is the 33018 tapered roller bearing suitable for?

Typical applications include general mechanical engineering and gearbox construction, as well as in powertrains where high radial forces are combined with axial guiding forces. As a single tapered roller bearing can only accommodate axial loads in one direction, designers usually arrange the bearing in a mirror-image configuration with a second bearing. This arrangement ensures precise shaft guidance and provides stable support for alternating load directions during operation.

What are the advantages of the integrated sheet steel cage?

The integrated sheet steel cage guides the tapered rollers precisely and maintains a uniform spacing between them on the raceway. This cage design is resistant to lubricants and is designed for operating temperatures ranging from –30 to +120 degrees. Manufactured to standard tolerances (tolerance class P0/PN or ABEC 1), the roller bearing meets the typical requirements for concentricity and fitting accuracy in standard industrial applications.
