Angular contact ball bearing introduction

2020-04-17

Angular contact ball bearings mainly bear large one-way axial load.The larger the contact Angle, the greater the bearing capacity.The cage is made of steel, brass or engineering plastics and is stamped or turned according to bearing form or working conditions.There are also combinations of angular contact ball bearings, double row angular contact ball bearings and four point contact ball bearings.

Angular contact ball bearings can bear both radial and axial loads.Can work at higher speeds.The larger the contact Angle, the higher the axial bearing capacity.High precision and high speed bearings typically have a contact Angle of 15 degrees.Under the action of axial force, the contact Angle increases.Single row angular contact ball bearing can only bear axial load in one direction, and additional axial force will be generated when bearing radial load.And the axial displacement of the shaft or shell can only be limited in one direction.If paired, the outer ring of a pair of bearings is opposite, that is, the wide end faces the wide end face and the narrow end faces the narrow end face.This avoids additional axial forces and limits both directions of the shaft or housing within the axial range.

Angular contact ball bearings can bear radial and axial loads, because the raceway of its inner and outer rings has relative displacement on the horizontal axis combined load (single row angular contact ball bearings can only bear one direction of axial load, so it is usually installed in pairs).Therefore, a pair of installations is usually used.Cage materials are brass, synthetic resin, etc., according to the bearing form, conditions of use and distinction.

Single row angular contact ball bearing

The characteristics of (1)

You can load radial and axial loads in one direction.

The contact Angle between the ball and the inner and outer circles is the contact Angle.The larger the contact Angle, the greater the axial load capacity, but not conducive to high-speed rotation.In addition, the smaller the contact Angle, the better the high-speed rotation, but the smaller the axial load capacity.

Usually, use two opposite bearings and adjust the internal clearance.

(2) scope of application

Hydraulic pumps, vertical pumps, in addition to radial load, but also bear axial load.

/ (3) format

According to the contact Angle, it can be divided into 15°, 25°, 30°, 40°, etc.

Double-mounted angular contact ball bearings

The characteristics of (1)

By combining two or more single row angular contact ball bearings, the stiffness of the bearings can be increased to enable them to withstand axial loads in two or more directions, or to apply a preload.

(2) scope of application

Machine tool spindle, grinding spindle, etc., need to improve the rotation precision and stiffness of the shaft.

(3) format

According to the bearing layout to be assembled, there are rear assembly type (DB), front assembly type (DF) and parallel combination type (DT).

Double row angular contact ball bearings

The characteristics of (1)

Double row inner ring and double row outer ring axial ball bearings can bear axial load in two directions.

(2) scope of application

Electromagnetic clutch for automotive air conditioning
