Tapered Roller Bearings FAG 30306

The FAG single-row tapered roller bearing 30306 (30 × 72 × 20.75 mm) can accommodate high radial and axial loads and features a sheet steel cage.

The FAG 30306 tapered roller bearing accommodates shafts with an internal diameter of 30 mm in housings with an external diameter of 72 mm. With a total width of 20.75 mm, this single-row roller bearing accommodates both radial and unilateral axial loads. The tapered arrangement of the rolling elements ensures line contact on the raceways, enabling the bearing to transmit high forces. You will receive a complete tapered roller bearing in a standard design, manufactured to tolerance class P0/PN or ABEC 1 for general mechanical and plant engineering.

What is the 30306 tapered roller bearing suitable for?

This roller bearing is particularly suitable for bearing arrangements subject to combined radial and axial loads. Typical applications include the mounting of gearbox shafts and drive shafts subjected to combined loads. As single-row tapered roller bearings, by their design, can only accommodate axial forces in one direction, designers usually fit a second bearing in a mirror-image configuration opposite the first. This paired arrangement supports the shaft in both axial directions and allows for the precise adjustment of the operating clearance.

What are the distinctive features of the version with a sheet steel cage?

The integrated sheet steel cage guides the tapered rollers evenly along the inner ring raceway and covers a permissible temperature range from –30 to +120 degrees. The metal cage construction withstands lubricants and impact loads in the operating environment. As this is an open design without abiding sealing discs, the bearing location requires external sealing within the housing. The open design allows for flexible lubrication with bearing grease or gear oil, depending on the specific operating conditions.
