The “non-tube” internal return design of the inch series incorporates balls in each circuit removed from the raceway and returned to it by solid metal deflector pins. This design eliminates the need for failure-prone return tube components and delivers high-speed operation, says the vendor. Hardened all-metal recirculation deflectors are blended to match the thick-walled nut surface for easy installation without special preparation. Inch series precision ground ball screws are available in sizes ranging from 3/8 in. to 6 in. in diameter, with leads from 0.1 in. to 1 in, and overall lengths up to 60 ft.
