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).
The KB series is available in standard, adjustable, or open style, which incorporates bottom plates and mounting screws to ensure the bushing remains in proper position.
