Cylindrical Roller Bearings

Product Description

Cylindrical roller bearing is separable bearing with easy mounting and dismounting characteristics. There are single row, double row and four row cylindrical roller bearings.

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. The enhanced cylindrical roller bearing can carry a high load, with 2 E, *2E, 3 E and *3E series as the basic designs. 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.
