Tapered Roller Bearings FAG 30318

The 30318 tapered roller bearing accommodates combined radial and axial forces and, with dimensions of 90 × 190 × 46.5 mm, provides a robust bearing arrangement.

The 30318 tapered roller bearing is a single-row roller bearing in a standard design. It supports shafts under high radial loads whilst simultaneously absorbing axial forces from one direction. The component is manufactured by FAG Wälzlager and is supplied as a complete bearing unit. It consists of an inner ring with a set of rollers and the corresponding outer ring. As it is manufactured to tolerance class P0/PN or ABEC 1, the unit fits dimensionally accurately into standardised housing fits.

What is the FAG 30318 tapered roller bearing suitable for?

Typical applications include general mechanical engineering, gearboxes and industrial drive systems. As a single-row tapered roller bearing, by its very design, only supports axial forces in one direction, designers usually fit a second bearing in a mirror-image configuration to act as a counter-bearing. The tapered rollers roll on the raceways without kinematic forced slip. As a result, the bearing operates with even force distribution across the entire contact line, even under continuous load.

What are the characteristics of the sheet steel cage?

The sheet steel cage maintains a uniform spacing between the rolling elements and reliably guides the rollers along the raceway. This cage design is dimensionally stable and operates within a temperature range of –30 to +120 degrees Celsius. During assembly, the design facilitates fitting: the outer ring can be fitted separately from the inner ring, together with the roller ring. Fitters then adjust the required operating clearance or a specific preload by adjusting the position of the mating bearing.
