Cylindrical Roller Bearing Single Row 300*460*74mm Nu1060

The cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bearing radial loads. The friction between the rolling element and the collar edge is small, suitable for high-speed rotation. According to the presence or absence of ribs on the ring, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU and NN. The bearing is a separable structure with inner and outer rings.

Cylindrical roller bearings without retaining edges on the inner or outer rings can move relative to the axial direction, so they can be used as free end bearings. A cylindrical roller bearing with double ribs on one side of the inner and outer rings, and a single rib on the other side of the ring, which can withstand a certain degree of axial load in one direction. Generally, steel plate stamped cages or copper alloy solid cages are used. But some also use polyamide shaped cages.

The cylindrical roller is in line contact with the raceway and has a large radial load capacity. Suitable for withstanding heavy loads and impact loads, as well as high-speed rotation.

The raceway and rolling body of cylindrical roller bearings are geometrically shaped. After improved design, it has a high load-bearing capacity. The new structural design of the retaining edge and roller end face not only improves the axial load-bearing capacity of the bearing, but also improves the lubrication conditions in the contact area between the roller end face and the retaining edge, improving the service performance of the bearing.
