The Advantages of WSBC Angular Contact Ball Bearings

Time：2020.05.14  Source：Roller Bearings Suppliers

Angular contact ball bearings are ball bearings with raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to withstand combined loads, that is, radial and axial loads acting simultaneously.

The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. The contact angle is defined as the angle between the line connecting the point of contact of the ball and the raceway in the radial plane angle.

Wuxi Spark Bearing Co.,Ltd has strong ability to manufacture of Angular contact ball bearings, Angular contact ball bearings are suitable for high speed and high precision rotation.

Features of Angular Contact Ball Bearings

Two single row angular contact ball bearings combined on the back side share inner ring and outer ring, which can bear radial load and bidirectional axial load

Non-grooved bearings are also of sealed type,the following some tips:

Main applicable cages:

Steel plate stamping cage (bowl-shaped...Single row;S shape, crown shape...Double row)

Copper alloy or phenolic resin cut cage, synthetic resin forming cage

Non-grooved bearings are also of sealed type,the following some tips:

Main applications of Angular Contact Bearings:

Single column: machine tool spindle, high frequency motor, gas turbine, centrifuge, small car front wheel, differential pinion shaft

Double column: oil pump, roots blower, air compressor, all kinds of transmission, fuel injection pump, printing machine

Four point contact ball bearing

It can bear radial load and bidirectional axial load

Single bearing can replace the angular contact ball bearing with front or back combination It is suitable for bearing pure axial load or composite load with large axial load component

This type of bearing can form one of the contact angles (PCR) when it is under axial load in any direction, so that the ring and the ball are in total contact with the double-sided point on any contact line

Main applicable cages:

Copper alloy cut cage

Main uses:

Aircraft jet engines, gas turbines

Summarize,The Advantages as below:

1. Simple structure;

2. the limit speed is relatively high;

3. The friction torque is relatively small;

4. It can bear both radial and axial loads at the same time;

5. The same external dimension is larger than the dynamic and static load capacity of the deep groove ball bearing;

6. High rotation accuracy and low noise.

Based on the above advantages, angular contact ball bearings are the first choice for high speed, high precision and low noise precision bearings.

Advantages of paired installation:

If installed in pairs, make the outer ring of a pair of bearings opposite, that is, the wide end faces the wide end face and the narrow end faces the narrow end face.This avoids causing additional axial forces and allows the shaft or housing to be confined within the axial clearance in both directions.Because the raceway of the inner and outer rings of angular contact ball bearing can have relative displacement on the horizontal axis, it can bear both radial load and axial load -- combined load (single row angular contact ball bearing can only bear one direction axial load, so it is usually installed in pairs).

The material of the cage is nylon, synthetic resin, etc., which is distinguished according to the bearing form and service conditions.

Importance of paired installation:

The installation of angular contact ball bearings is more complicated than that of deep groove ball bearings.Good installation can greatly improve the working accuracy and bearing life of the main engine.Otherwise, not only the accuracy is not up to the requirements, life will be affected.

Installation form of angular contact ball bearing:

There are back to back, face to face and in series.When mounted back-to-back (the broad end faces of the two bearings are opposite), the contact Angle line of the bearing diffuses along the direction of the rotary axis, which can increase the rigidity of its radial and axial support angles and maximize its anti-deformation capacity.When the bearings are mounted face to face (the narrow end faces of the two bearings are opposite), the contact Angle of the bearings converges towards the direction of the axis of rotation, and the ground bearing Angle is less rigid.As the inner ring of the bearing extends out of the outer ring, when the outer rings of the two bearings are pressed together, the original clearance of the outer ring is eliminated, which can increase the preloading load of the bearing.
