Tapered Roller Bearings SKF 30306

The SKF 30306 tapered roller bearing accommodates combined radial and axial loads whilst maintaining compact overall dimensions of 30 × 72 × 20.75 mm.

The 30306 tapered roller bearing is a single-row roller bearing in standard design from the SKF Explorer performance class. It consists of an inner ring with a set of rollers and a separate outer ring, and is designed as a complete tapered roller bearing. Thanks to the line contact between the tapered rollers and the raceways, this design can accommodate high radial forces as well as single-direction axial loads in demanding industrial applications.

What is the 30306 tapered roller bearing suitable for?

Design engineers primarily use this bearing where high radial forces are combined with axial forces. Typical applications include industrial gearboxes, shaft bearings and guide rollers in general mechanical engineering. As a single tapered roller bearing can only accommodate axial forces in one direction, it is usually fitted in pairs in an O or X arrangement opposite a second bearing, in order to support both load directions and guide the shaft precisely.

What are the distinctive features of the sheet steel cage and the design?

A dimensionally stable sheet steel cage guides the rolling elements along the inner ring raceway and retains the lubricant within the contact area. The open bearing allows operating temperatures ranging from -30 to +120 degrees and can be adapted to the type of lubricant selected by the customer. As the inner and outer rings can be fitted separately, installation in housings and on shafts is particularly straightforward, as both rings can be positioned independently of one another.
