Introduction

Single row cylindrical roller bearings are available in many designs, series and sizes. The major design differences between the bearings presented in this section are in:

●the cage design and material.

●the configuration of the inner and outer ring flanges.

Single row cylindrical roller bearings are usually subjected to radial force only, compared with the ball bearings of the same size, the radial bearing capacity is increased by 1.5-3 times, the rigidity is good, impact resistance, it is especially suitable for rigid support, but also support the short shaft, thermal elongation caused by axial displacement of the shaft and the installation and removal of the machine accessories that need to separate type bearings.

Features and Benefits

●Low friction (Roller end / flange contact area)

The open flange design, together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capacity.

●Long service life

The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.

●Enhanced operational reliability

The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.

●Separable and interchangeable

The separable components of XRL cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.

●High speed capability

The cage designs are suitable for high speeds, rapid accelerations and peak loads.

Structural Features

Cylindrical roller and raceway for line contact bearing. Large load capacity, mainly bearing radial load. The friction between rolling body and ring retaining edge is small, suitable for high speed rotation. According to whether the ring has a side, it can be divided into NU, NJ, NUP, N, NF and other single-row cylindrical roller bearings, and NNU, NN and other double-row cylindrical roller bearings. The bearing is a detachable structure with inner and outer rings.

Single row cylindrical roller bearing has the advantages of easy assembly, large bearing load, high limit speed, strong reliability and long service life.

Application

It is mainly used for large motor, machine tool spindle, engine front and rear supporting shaft, train and passenger car axle supporting shaft, diesel engine crankshaft, automobile tractor gearbox, etc.
