IKO Bearing LMS4 High Carbon Steel Miniature Linear Bushing, 4 mm Inside Diameter, 8mm Outside Diameter, Standard Type, Without Seal, High Accuracy Grade

Linear Bushing LM is a high precision linear motion rolling guide which travels along a shaft to achieve endless linear motion. In the external cylinder, a retainer, steel balls, etc. are compactly incorporated. Wide variations in size are available for selections suitable for each application. Steel balls are accurately guided by a retainer, so low frictional resistance and stable linear motion can be achieved. It is easy to use Linear Bushings instead of conventional plain bushings, because both types are used with a round shaft, and no major redesign is necessary. For each dimensional series, standard, adjustable clearance and open types are available with and without seals, so the best linear bushing for the application may be selected. Linear Bushings made of stainless steel are also available. This type is suitable for applications where corrosion resistance is important.
