Press Release Summary:
SKF/TCM precision ground ball screw assemblies enable precise positioning of moving parts in computer-controlled machinery. No-tubing, internal return design incorporates balls in each circuit removed from raceway and returned by solid metal deflector pins. One-piece nut construction flanges provide built-in accuracies for concentricity, squareness, and straightness. Sizes range from 3/8 to 6 in. dia with leads from 0.100-1.000 in. and lengths up to 60 ft.
Original Press Release:
SKF/TCM Precision Ground Ball Screws for Linear Actuation Feature Robust Design for Durability
SKF/TCM precision ground ball screws feature a robust internal recirculation system design to promote durability and high performance in the most demanding linear-actuation applications. These ball screw assemblies enable precise positioning of moving parts in computer-controlled machinery utilized in a wide range of industries, including robotics, machine tool, aerospace, automotive, marine, power generation, and instrumentation.
Their unique "no-tubing" internal return design incorporates balls in each circuit removed from the raceway and returned to it by solid metal deflector pins. This design eliminates external parts (and the possibility of damage upon installation) and delivers high-speed operation enhanced without the presence of conventional burst-prone return tubes.
Hardened all-metal recirculation deflectors are blended to match the thick-walled nut surface for easy installation without special preparation; one-piece nut construction flanges provide built-in accuracies for concentricity, squareness, and straightness; and integral nylon wipers at each end of the nut protect against contamination.
SKF/TCM standard ground ball screws are available in sizes ranging from 3/8 in. to 6 in. diameter with leads from 0.100 in. to 1.000 in. and lengths up to 60 ft. Preloaded and non-standard sizes, configurations, and special materials can be custom-designed and manufactured to satisfy particular application requirements.
SKF/TCM further offers dedicated resources and capabilities to repair and/or upgrade all brands of precision ball screws. Free inspections, quick turnaround, and 24-hour emergency services are available.
