SKF® profile rail guides incorporate unique pre-lubricated reservoirs designed as standard in all carriages to optimize lubrication of rails for reliable performance and contribute to maintenance-free operation of guides for extended time periods.
These guides can provide precise positioning, smooth operation, high load-carrying capacity, high stiffness, unlimited stroke, and low-noise operation for a variety of linear motion applications in the semiconductor, electronics, and medical industries, among others.
They feature a profile rail with 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. Two-point contact of rolling elements with the raceways promotes high operational speeds with quiet running and a low coefficient of friction.
SKF profile rail guides are available in a variety of sizes and with various slide configurations (normal, wide, long) and lengths to satisfy specific application requirements. Ready-to-mount units help make installation easy and minimize adjustment requirements. Guides can be customized (including specific preload) to satisfy specific application needs.
