Uniline System is a family of pre-assembled linear units boasting a compact size and high speed ensured by the COMPACT RAIL roller bearings, mounted on a self-sustaining extruded aluminum profile. The linear units are driven by a steel reinforced polyurethane belt system. The horizontal seals and the raceway cleaners fitted on both ends of the carriage ensure full protection from dirt. The linear actuator profile is compatible with an endless number of widely available standard fixing accessories.
