Overview of Cylindrical roller bearings

Cylindrical roller bearings: cylindrical roller and raceway are linear contact bearings.Large load capacity, mainly bear radial load.The friction between the rolling body and the ring edge is small, which is suitable for high speed rotation.The bearing is a structure with separable inner and outer rings.The cylindrical roller bearings with inner or outer rings without flanges can be used as free-end bearings because the inner and outer rings can move relative to each other in the axial direction.One side of the inner ring and outer ring is provided with double flaps, and the ring on the other side is provided with a cylindrical roller bearing with a single flaps, which can withstand a certain degree of axial load in one direction.

Features of Cylindrical roller bearings

The rolling body is a centripetal rolling bearing of a cylindrical roller.The internal structure of cylindrical roller bearings adopts rollers arranged in parallel, and a spacer or isolation block is installed between the rollers, which can prevent the tilt of the rollers or the friction between the rollers, and effectively prevent the increase of rotation torque.

Applications of Cylindrical roller bearings

Large and medium-sized motors, locomotives and vehicles, machine tool spindles, internal combustion engines, generators, gear boxes, vibrating screens and lifting and transport machinery.

Classification of cylindrical roller bearings

Cylindrical roller bearings can be divided into single row, double row and multi-row cylindrical roller bearings and other different structures according to the different number of rows of rollers installed.Different structures of bearings are also shown in the design of the position of the flange.Among them, the commonly used cylindrical roller bearings have the following forms:

Single-row cylindrical roller bearings: Single-row cylindrical roller bearings are separable bearings for easy installation and disassembly. Both rings can be fitted tightly. The modified contact line between the roller and the raceway reduces stress concentration.

Double row cylindrical roller bearings: double row cylindrical roller bearings belong to swimming bearings, and their separability makes installation and disassembly very convenient.

Both rings can be fitted tightly.Double-row cylindrical roller bearings allow almost no inclination.
