How to Reduce Angular Contact Ball Bearing Damage?


Angular contact ball bearing is a widely used bearing. Different accuracy grades have different prices. The higher the accuracy, the more expensive the price. If the bearing is damaged, it is necessary to replace the bearing on the one hand, and on the other hand, the shutdown will bring losses. Therefore, it is necessary for users to reduce the loss of bearings. The life of rolling bearings has a certain dispersion even under good operating conditions. For important equipment, especially angular contact ball bearings that work under harsh conditions, whether the angular contact bearings installed in them work reliably and how long they can continue to run has become a special concern for customers. Today, Luoyang FV will talk about how to reduce the damage of angular contact ball bearings.

To reduce bearing damage, some diagnosis is necessary, mainly as follows:

1. Observe the fractured part of the angular contact ball bearing with a high-magnification scanning electron microscope, check whether there are fatigue arcs and a large number of corrosion pits in the crack area, whether there is a fan-shaped pattern, and what the fan-shaped pattern looks like.

2. Check the bearing stress. Bearings are mainly subjected to three kinds of stress: explosion stress, assembly stress and thermal stress. Fire in an angular contact ball bearing is an abnormal phenomenon. Abnormal defects such as burns often seriously affect the appearance quality and product performance of the workpiece, especially for precision workpieces or important workpiece surfaces that require high appearance quality.

3. When induction heating is observed in the production of angular contact bearings, the ignition between the angular contact bearing and the inductor is often not a point contact, and the noise generated by the angular contact ball bearing is very sensitive. Therefore, in order to ensure the smooth operation of angular contact ball bearings, some measures should be taken, such as appropriate control of sintering conditions to make the alloy structure into a single phase, and anti-corrosion process measures can also be taken; another method is to generate compressive stress on the outer surface of the workpiece to prevent the tensile stress in use.

Bearing damage is inevitable. What we need to do is to take some measures as soon as possible when there is a small damage to the bearing, which can effectively alleviate the damage and prolong the service life of the bearing. Welcome to contact us!
