SKF profile rail guides reportedly provide precise positioning, smooth operation, high load-carrying capacity, high stiffness and unlimited stroke for linear motion applications in the semiconductor, electronics and medical industries.
 
Feature four precision-ground raceways and a slide unit with four ball circulation paths. The square configuration of raceways results in a guidance system with good rigidity able to accommodate equal load capacity in all directions. Incorporate a two-point contact of rolling elements with the raceways promoting high-speed operation, quiet running and low friction.
 
Includes high-performance, heavy duty, compact, medium and miniature series. Each is available with various slide configurations (normal, wide, long) and lengths.  Different carriage designs can meet particular load and stiffness demands (long carriages promote higher load-carrying capacity and wide carriages promote higher moment stiffness).  Guides with specific preload can be supplied.
