C-Lube Ball Spline MAG is a compact linear motion rolling guide which achieves endless linear motion of an external cylinder along a spline shaft. With original C-Lube technology, its performance makes the products different from others, providing superior cost performance for your machines. Maintenance free for 20,000 km or 5 years minimizes the amount of lubricant required and contributes to the global environment protection. Stable high accuracy and rigidity are ensured in operations even under fluctuating loads with changing direction and magnitude or complex loads.
