Product Catalog

The cylindrical roller and the raceway are linear contact bearings. The load capacity is large, mainly bearing radial load. The friction between the rolling element and the rim is small, which is suitable for high-speed rotation. According to whether the rim has rim, 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 structure with separable inner ring and outer ring.

A cylindrical roller bearing with an inner ring or an outer ring without a rib. The inner ring and the outer ring can be moved relatively axially, so it can be used as a free end bearing. A cylindrical roller bearing with double ribs on the inner ring or outer ring and a single rib on the other ring can withstand a certain degree of axial load in one direction. Generally, a steel plate stamped cage is used, or a copper alloy solid cage is used. However, some polyamide shaped cages are also used.

The main purpose of this type of bearing

Large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens and lifting and transportation machinery.
