Our metric linear motion bearings, ideal for single-direction motion applications, are widely used in Europe. Offered in a wide variety of shaft shapes, these bearings are available in chrome or stainless steel with either a steel or resin retainer. The slide block housings are also available in several styles. These bearings contain internal seals (UU).
