Product Description

Tapered Roller Bearings 30300 Series utilize conical rollers and raceways, arranged so that the rollers and raceways meet at a common apex. The rollers are guided by contact between the large end of the roller and a rib on the inner ring. This provides high capacity for radial and single thrust loads.

Precision Tapered Roller Bearings 30300 Series

Taper Roller Bearings 30300 Series are produced in a variety of versions to adapt to the various types of applications. The versions available are indeed single-row and double-row bearings, both in inch and metric size.

Tapered Roller Bearings 30300 Series

The constructional shape of the Precision Tapered Roller Bearings 30300 Series makes them especially suitable for combined loads (radial and axial). They always have to be pack-mounted, with or without pre-load, because continuous contact of the relevant rolling elements has to be guaranteed.
