Tapered Roller Bearings FAG 33208

The 33208 tapered roller bearing from FAG Wälzlager, measuring 40x80x32 mm, provides a robust guide for combined radial and axial forces.

This single-row tapered roller bearing 33208 simultaneously accommodates high radial forces and single-sided axial forces. In this design, the truncated cone-shaped rolling elements run on inclined raceways on the inner and outer rings. The open bearing is designed for operating temperatures ranging from -30 to +120 degrees. A guided sheet steel cage maintains an even spacing between the rollers and ensures smooth running.

What loads and installation situations characterise the 33208 tapered roller bearing?

The design is suitable for bearing locations where high combined loads act on rotating shafts. As a single-row bearing can only accommodate axial forces in one direction, it is usually fitted in pairs, facing each other, in mechanical and plant engineering. The separable design allows the inner and outer rings to be fitted separately, which simplifies installation and maintenance.

What are the key features of the design and the P0/PN tolerance class?

The complete tapered roller bearing is manufactured to the standard tolerance class P0/PN (corresponding to ABEC 1), which meets the industry’s standard requirements for dimensional accuracy. As the outer ring and inner ring assembly are not permanently joined, both components can be press-fitted separately. The axial bearing clearance is only adjusted during assembly by positioning the bearing against a counter-bearing. External lubrication protects the exposed working surfaces.
