Tapered Roller Bearings FAG 33122

The single-row tapered roller bearing 33122, measuring 110 × 180 × 56 mm, withstands high radial and unilateral axial loads in industrial applications.

The 33122 tapered roller bearing from FAG is a separable rolling bearing designed for demanding mechanical applications. With an inner diameter of 110 mm, an outer diameter of 180 mm and a width of 56 mm, this single-row bearing supports heavy shafts. Thanks to the line contact of the tapered rollers, these components can transmit high forces whilst maintaining a compact design. The inner and outer rings can be fitted separately, which simplifies maintenance and installation in mechanical engineering.

What is the 33122 tapered roller bearing suitable for in operation?

This rolling bearing simultaneously accommodates high radial loads and single-sided axial loads. Typical applications include gearboxes and mounted shaft systems where rigid guidance is required. As a single tapered roller bearing can only accommodate axial forces in one direction, it is usually fitted in a mirror-image pair with a second bearing. This arrangement supports the shaft in both directions.

What are the key considerations regarding the tolerance and cage design of the 33122?

The bearing is fitted with a sheet steel cage that guides the tapered rollers and is suitable for use in temperatures ranging from -30 to +120 degrees. It is manufactured to the standard tolerance P0 or ABEC 1, suitable for standard applications in industrial environments. As the outer ring and inner ring are not permanently joined, fitters set the required operating clearance directly during assembly via the axial preload.
