Linear Rail System Miniature Linear Rail System Miniature Linear Rail System Ball Screw Types and features [SBM type] Standard type of miniature. Block End plate End seal Support Unit [SBML type] Block guide Ball Block length is modified type to increase load capacity. Retainer Cross Roller Guide [Feature of structure] SBC Miniature linear rail system utilizes two rows of ball bearings which make four point contact between the rail and block. This design achieves both a slim profile and high rigidity. The special engineered plastic is used for the end-plate allows for long life ball recirculation. [Ball retention] [SBMW type] The width and length of linear block and rail are modified to increase load ratings and permissible moments. [Low noise] With a ball return path made from engineered plastic, contact noise between the balls and block wall is removed, therefore achieving low noise. [Smooth movement] The steel block, ball returns, and end caps are carefully engineered to act as a single path enabling smooth operation in both horizontal and vertical applications. [SBMWL type] It uses the same rail as SBMW type and it has the longest whole length of a block, making it the largest heavy load type among Miniture products. Robot Carrer Guide To retain the ball bearings inside the block, a wire retainer is used between the block and rail. With this retainer, the block can be carefully emoved from the rail without loosing ball bearings. [Excellent corrosion resistance] Both the rail and block are made from stainless steel for excellent corrosion resistance. This is ideal for semiconductor, life science, LCD, or other clean room production environments.

Linear Rail System Miniature Linear Rail System Miniature Linear Rail System Caution for mounting miniature through tap hole rail Ball Screw Miniature through tap hole rail If the mounting bolt is longer than overall mounting height, the bolt can protrude which can cause tinterference with the seal or bearing itself. Therefore, make sure the appropriate bolt selection. Support Unit Cross Roller Guide Robot Carrer Guide Memo
