Product description

Single-Row Cylindrical Roller Bearings




1.Inner ring or outer ring is separable, easy installation and disassembly;

2.Large radial bearing capacity, suitable for bearing heavy load and impact load;

3.The friction coefficient is small, suitable for high speed, and the limit speed is close to deep groove ball bearings;

4.N type and NU type can move axially and can be used as free end support;

5.The processing requirements are higher for the shaft or seat hole, to prevent relative deflection, so as to avoid contact stress concentration. 


Detailed Introduction

Cylindrical roller bearing rolling elements are cylindrical rollers, which are separable bearings, convenient for installation and disassembly. According to whether the ring has ribs or not, it can be divided into N, NU, NJ, NF, NUP single-row cylindrical roller bearings, NNU, NN double-row cylindrical roller bearings, and multi-row cylindrical roller bearings. Cylindrical roller bearings generally use copper alloy lathe-made solid cages or engineering plastic cages. When the speed is low and the load is large, it can be full-roller bearings without cage.







Cylindrical roller bearings have a linear contact between the rollers and the raceway. It has large load capacity, mainly bearing radial loads. The friction is low between the rolling element and the rib of the ferrule, suitable for high-speed rotation, requiring high coaxiality. Cylindrical roller bearings without ribs on the inner or outer ring, the inner and outer rings can move relatively to the axial direction, so they can be used as free end bearings. Cylindrical roller bearings can withstand a certain degree of unidirectional axial load, which is with double ribs on one side of the inner ring or outer ring and a single rib on the other side of the ring.


Our Single-row cylindrical roller bearings are famous for their long service life. The professional designed bearings have a certain axial load capacity while maximizing the radial load capacity. The cylindrical roller bearings for railway vehicles provided by us are internally controlled thermal process, so that the bearing surface has stable compressive stress and excellent overall impact resistance.



Main Application

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