A new linear guide rail system from SDP/SI (ISO 9001 + AS9100 Registered) features heavy-duty, low wear, low friction, quiet, maintenance-free operation, without the need for lubrication. The sliding element is a specially formulated polymer material best suited for hard anodized aluminum rails. The combination of the two yields low abrasion, which reduces alignment problems and assembly time. The carriage and rail combination is a compact, space-saving design with easy installation. The low, wide profile withstands high torque.
