TCM precision ground ball screws incorporate a robust internal return system designed for durability and high performance in demanding, linear-actuation applications. The ball-screw assemblies enable precise positioning of moving parts in a range of applications for the automotive, aerospace, injection molding, instrumentation, medical and machine tool industries. Their internal return design circulates the ball bearings to the opposite end of the nut through a hole drilled in the wall of the nut body. The nut is fitted with solid pickup pins and deflectors, which guide the balls through the return system. The design eliminates external parts and delivers high-speed operation enhanced without the presence of conventional return tubes. Standard, precision-ground ball screws are available in screw diameter sizes from 3/8 to 6 inches, leads from 0.100 to 1.000 inch and lengths up to 60 feet. Preloaded and nonstandard sizes, configurations and special materials can be accommodated.
