Product description

Double Row Cylindrical Roller Bearings

 

Features

1.The inner ring or outer ring can be separated, easy installation and disassembly.

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

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, can be used as free end support;

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

 

Detailed Introduction

Cylindrical roller bearing rolling parts 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 and other single-row cylindrical roller bearings, NNU, NN and other double-row cylindrical roller bearings, and also 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 structure without cage.

Double row bearing: NN, NNU type

The outer ring of the NN type bearing has no ribs, and there are ribs on both sides of the inner ring and a rib in the middle. Displacement in two directions in the axial direction between the shaft and the bearing housing is allowed. The outer ring of the NNU bearing has ribs on both sides and a rib in the middle, and the inner ring has no ribs. Displacement of the shaft relative to the bearing housing in two directions is allowed.

 

Applications

Double row cylindrical roller bearings are mainly used in large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and hoisting and transporting machinery, etc.
