Miniature Linear Guides


Miniature Linear guide provides precision low friction guidance of payloads for machine and instruments applications.   One or multiple bearing blocks can be mounted on a linear guide rail.   Each bearing block has two rows of recirculating balls that engage the precision ground rail allowing almost frictionless movement.   These products are available in industry standard sizes as small as size 3 up to size 15.  Rail length up to 1000 mm (39.4 inches) long.  

Excellent choice for multi-axis motion systems used in medical diagnostic machines, lab automation systems, desktop robot systems, and other small devices.
