Tapered Roller Bearings FAG 30216

The FAG 30216 tapered roller bearing, with dimensions of 80 × 140 × 28.25 mm, accommodates high radial loads as well as unilateral axial loads in mechanical engineering applications.

The single-row tapered roller bearing 30216 combines an inner ring with a set of rollers and a removable outer ring to form a separable bearing unit. This split design facilitates sequential installation into housings and onto shafts. Thanks to the linear contact between the truncated cone-shaped rollers and the hardened raceways, the component is suitable for demanding industrial applications. The integrated sheet steel cage guides the rolling elements with minimal vibration and maintains operation within a temperature range of -30 to +120 degrees.

In which installation situations does the 30216 tapered roller bearing prove its worth?

The 30216 tapered roller bearing is primarily used where high radial forces and unidirectional axial forces act simultaneously. Typical areas of application include industrial gearboxes and heavily loaded bearings in general plant and machine construction. As a single bearing can only absorb axial forces in one direction, they are often fitted in pairs in an O or X configuration. This allows shafts to be supported on both sides without play, thereby increasing the rigidity of the structure.

What is important to consider regarding installation and the P0/PN tolerance class?

The 30216 tapered roller bearing complies with the standard tolerance class P0/PN (comparable to ABEC 1) and thus meets the usual precision requirements for industrial applications. As the inner and outer rings are fitted separately, you only set the operating clearance or preload during installation via the mating bearing. Ensure that the contact surfaces on the 80 mm diameter shaft shoulder and the 140 mm housing bore are clean. A well-maintained sheet steel cage ensures low-friction lubricant distribution across the entire operating range.
