Bowman Bearing Selector

The Bowman Bearing Selector

The Bowman Bearing Selector has been developed to assist you in selecting the correct bearing for your project. This bearing selector reduces the uncertainty when selecting bushes and you can rest assured that whether you are in the design process or replacing a bearing in an existing application that you have selected the right one. The Bowman Bearing Selector will search our entire product range and select the bearing that corresponds to a set of parameters that you enter into it.

If you already know which bearing you need, you can use the bearing selector to review the technical information on that particular bearing. The bearing selector will show you the tolerances, load ratings, maximum speed, material information and much more.
