Tapered Roller Bearings FAG 33209

The FAG 33209 tapered roller bearing (45x85x32 mm) is a single-row rolling bearing designed to withstand high radial and unilateral axial loads in mechanical engineering applications.

The FAG 33209 tapered roller bearing is a separable, single-row roller bearing in a standard design. With a bore of 45 mm, an outer diameter of 85 mm and a width of 32 mm, this roller bearing is suitable for industrial applications involving combined radial and axial loads. The inner ring, including the roller set, and the outer ring can be fitted separately. This makes the bearing easier to maintain in machines and shaft systems. The sheet steel cage guides the tapered rollers at operating temperatures ranging from -30 to +120 degrees.

What loads can the single-row tapered roller bearing 33209 accommodate?

The single-row tapered roller bearing accommodates high radial forces and unidirectional axial forces occurring simultaneously. Typical applications include gearboxes and mounted shaft assemblies in general mechanical engineering. As a single tapered roller bearing can, by design, only accommodate axial loads in one direction, it is usually fitted in pairs in an O or X arrangement with a second mating bearing. This arrangement stabilises the shaft and allows the axial bearing clearance to be precisely adjusted.

What are the characteristics of the sheet steel cage and tolerance class P0 in model 33209?

The steel sheet cage keeps the tapered rollers in position during rotational movement and is suitable for operating temperatures ranging from –30 to +120 degrees. Manufacture to tolerance class P0 (equivalent to PN or ABEC 1) defines standard precision for common fits in mechanical engineering. As the design is open, lubricant and sealing are provided via the surrounding housing structure.
