    WSBC Ceramic Bearings

    The Advantages of Ceramic Bearings First, because ceramics are almost not afraid of corrosion, ceramic rolling bearings are suitable for operation under harsh conditions full of corrosive media. Second, because the density of ceramic rolling ball is lower than steel, the weight is much lighter, so the centrifugal action of the outer ring can be reduced by 40% when rotating, and then the service life is greatly exten...

    Three reasons you should consider Custom Bearings

    When it comes to bearings, it’s important to find the right parts for your exact needs. However, that’s not always possible if you only look for standard parts.When it comes to standard bearings, it’s not uncommon for them to be either over- or under-qualified to perform specific tasks for your application. It’s like trying to dig a fence hole post in your backyard. You wouldn’t use an excavator because it’s overkill. ...

    How To Judge WSBC Bearing Damage

    1. Vibration of WSBC bearing   WSBC bearing vibration is very sensitive to bearing damage, such as peeling, indentation, rust, cracks, abrasion, etc. will be reflected in the WSBC bearing vibration measurement, so it can be measured by using a special bearing vibration measuring device (frequency analyzer, etc.) The magnitude of the vibration can not be inferred by the frequency division. The measured value varies wit...
