Linear ball bearings, linear plain bearings

Linear ball bearings – also known as ball bearing bushes or shaft guides – use linear motion to guide a machine element along a cylindrical shaft with as little friction as possible. In contrast to conventional ball bearings, they therefore also have axial ball recirculation. Linear plain bearings differ from linear ball bearings in the technology used for the sliding process and the type of bearing. The linear plain bearings are a plain bearing bush with a special coating.
