INDUSTRY COMPONENT

Return system

Ball screw return system redirects balls through a return tube to maintain continuous recirculation in ball screw assemblies.

Component Specifications

Definition
The ball screw return system is a critical component in ball screw mechanisms that facilitates the continuous recirculation of ball bearings. It consists of a return tube or channel that captures balls at the end of the nut's helical groove and redirects them back to the starting point, ensuring uninterrupted motion transfer with minimal friction and wear.
Working Principle
Operates by guiding ball bearings through a closed-loop path: balls exit the load-bearing groove, enter the return tube, travel parallel to the screw axis, and re-enter the groove at the opposite end, maintaining constant ball circulation for smooth linear motion.
Materials
Typically made from hardened steel (AISI 52100 or equivalent), stainless steel (AISI 440C for corrosion resistance), or engineering plastics (POM, PA) for lightweight applications. Surface hardness: 58-62 HRC for steel components.
Technical Parameters
  • Noise Level <65 dB(A)
  • Temperature Range -30°C to +120°C
  • Return Tube Diameter 3-20 mm
  • Ball Diameter Tolerance ±0.001 mm
  • Maximum Operating Speed Up to 3 m/s
Standards
ISO 3408, DIN 69051
