Roller Bearing

Product Description1. The main components of cylindrical roller thrust bearing; The cylindrical roller and cage thrust assembies, the shaft washers, and the housing washers. 2. The cylindrical roller thrust bearings are simple in form and design. The bearings are produced in single row and double row designs. 3. The cylindrical roller thrust bearings are suitable for arrangements that have to support heavy axial loads. 4. And they are relatively insensitive to shock loads, are very stiff and requre little axial space. As standard they are available as single direction bearings and can only accommodate axial loads acting in one direction. Their rollers are designed to carry a maximum load. Cylindrical roller bearing is mainly applied in electrical motors, machine tools, oil production, steel mills, loading and moving machineries and other industrial machineries.

Cylindrical roller bearings are classified by the rib types.  The outer ring of a NU-type bearing has two ribs and the inner ring has no rib. The inner ring of a N-type bearing has two rib and the outer ring has no rib.

NU-type and N-type cylindrical roller bearings are used at a floating end. As seperable bearings, they are easy for assembly and dismantle, with tight fit suitable ofr both inner and outer rings.

The outer ring of a NJ-type cylindrical roller bearing has two ribs and the inner ring has one, being able to endure the axial force in one direction.

A NUP-type cylindrical roller bearing is used at an fixed end, being able to endurre the axial forces in two directions. The outer rings of such bearings have two ribs each, and the inner rings have one fixed rib and one movable rib each. One NJ-type cylindrical roller bearing and one angle ring HJ make up of a fixed-end bearing similar to NUP type.
