Angular-contact Ball Bearings

Angular-contact ball bearings are bearings that can take a radial load and a thrust load in one direction.
There are several types of ball bearings, and they differ in the environment in which they are used, for example, the case focusing on load is described below.

Deep-groove ball bearings A general type of bearing that can support thrust loads parallel to the shaft (axial loads) and radial loads perpendicular to the shaft.
Thrust ball bearing It can take thrust loads in one direction.
Angular-contact ball bearings It can take a radial load and a thrust load in one direction.

Angular-contact bearings look very similar to deep groove bearings, but their performance is different. The secret to this difference is in the raceway ring.

A deep-groove bearing is made up of an inner ring, which is a raceway, an outer ring, a cage, and balls. Angular contact bearings are made of the same parts. While the grooves of a deep groove bearing are symmetrical when viewed from the center, angular contact bearings have grooves at a certain angle that transmit force from one groove to the other in an oblique direction. This angle is called the contact angle. The larger the contact angle, the greater the thrust load that can be applied, but the slower the allowable speed. Basically, 15, 30, and 40 degrees are the standard angles. Some manufacturers have a contact angle of 25 degrees, while others have a different standard angle.

There are also the following types of angular bearings

  • Single-row angular bearings: Similar in appearance to deep groove bearings.
  • Double-row angular bearing: Structure in which single-row angular bearings are combined to form a single inner and outer ring.

Structure with inner and outer rings integrated by combining single row angular contact bearings.

There is also a combination angular bearing, which is used by combining two single row angular bearings. Since the combination has different characteristics, the combination can be changed to suit the environment.

However, this does not necessarily mean that single-row angular contact bearings are suitable for applications where loads are applied from both radial and axial directions. The choice between deep groove bearings and single row angular contact bearings depends on the operating conditions.

As mentioned earlier, deep groove bearings are common bearings that can take both radial and thrust loads, but they are not suitable for taking high thrust loads.
Angular contact bearings, on the other hand, have a contact angle that allows them to take a larger thrust load than deep groove bearings. However, they can only be used if the direction of the load is in one direction. The choice of bearing depends on the environment in which it is used, so care must be taken.

 

Naturally, we also manufacture angular contact bearings.

One of the features of our angular contact bearings is that they are less expensive than single row angular contact bearings. This is because a single double-row angular bearing is less expensive than two single-row angular bearings.

Since we manufacture bearings from a single piece by cutting, we can manufacture special shapes such as double row bearings without any problems. 
In addition, our bearings are made of resin and are used in the following special environments where metal bearings cannot be used.

  • Underwater: Can be used without worrying about rusting
  • In chemicals: Can be used without worrying about corrosion
  • High temperature environment: Heat-resistant resin is also available, so there is no need to worry about grease drying up.
  • Non-magnetic environment: Can be used in metal detectors, etc., because it is not magnetic.
  • Environment requiring insulation: Can be used in places where you don’t want electricity to pass through.

     

    We can help you select the right material. We can also manufacture small lots of 10 pieces.
    If you have any questions about bearings or plastics in special environments, please feel free to contact us for a consultation.
