* Execution in corrosion resistant steel. Strokelength 5-70 mm. In 3 sizes available. Weight 2-70 grams.?for rapid and precise linear motions.* PM frictionless slides, are ready-to-install 1-axis components for precise limited linear movements. THe crossed roller slides, use PM linear bearings, are factory play-free pre-loaded, to assure high grad in running accuracy, extreme low uniform coefficient of friction(<0.003) and a long operation lifetime.Each type is executed with attachment holes drilled to a standard configuration to permit a quick assembly in the application. The mounting surfaces of the slides are finished by precision grinding, to achieve the best possible operation results.
