Lubricating greases for ball screw and guide screw
　　It is important to consider loads, speed, accuracy, environment and power demands when people design line displacement equipments. No matter whether engineers choose forward ball screws, precise fixed ball screw or guide screw, they need to consider lubricating greases first. Choosing appropriate lubricating greases can reduce friction, reduce torsion, increase screw’s efficiency and prolong its life cycle.
ATS grease for ball screw can make the forward ball screws and fixed ball screws work precisely, smoothly and quietly. It can reduce abrasion and heat, and prolong their working life.
