Tapered Roller Bearings FAG 30305

The FAG 30305 tapered roller bearing accommodates combined radial and axial loads and has compact dimensions of 25 × 62 × 18.25 mm.

The 30305 tapered roller bearing is a single-row roller bearing from FAG in a standard design. With a bore of 25 mm, an outside diameter of 62 mm and a width of 18.25 mm, this design is engineered to accommodate both radial and axial forces simultaneously. The integrated sheet steel cage guides the tapered rollers evenly along the raceways. The product is supplied as a complete tapered roller bearing in tolerance class P0/PN or ABEC 1 and is designed for operating temperatures ranging from –30 to +120 degrees.

What loads can the 30305 tapered roller bearing accommodate?

Designs incorporating the 30305 tapered roller bearing are suitable for bearing locations where radial loads are combined with unidirectional axial forces. As tapered roller bearings are not self-retaining by design, the inner ring, together with the roller cage, can be pressed onto the shaft separately from the outer ring. This separate assembly simplifies handling when precisely aligning the housing and shaft in industrial mechanical engineering.

What are the key features of the sheet steel cage in the 30305 tapered roller bearing?

The dimensionally stable sheet steel cage maintains the rollers at a uniform distance and withstands temperatures ranging from -30 to +120 degrees. As an open rolling bearing, the unit requires appropriate lubrication via the housing using rolling bearing grease or lubricating oil. In practice, single-row tapered roller bearings are usually mounted in opposition to a second bearing. This axial alignment allows the desired bearing clearance to be precisely adjusted during final assembly.
