Machinery Design & OEM with Ball Transfer Units

An indispensable component for design engineers, Alwayse Ball Transfer Units are popular where loads and moving machinery parts require instant 3600 direction changes and zero offset.

With the world’s widest range, plus bespoke design capability, Alwayse are the experts in providing ball units to meet the most demanding requirements.

Precise movement and small linear motions (Mini Units)

With load balls from 4.8mm to 15.8mm diameter, Mini Units are ideal for accurate positioning and use in compact spaces. Applications include:

  • Miniature mechanisms e.g. photocopier paper drawers
  • Medical scanners
  • Robotics & Mechatronics
  • Measuring equipment
  • Optical & laser technologies
  • Glass processing – arris edging
  • Guides for small linear motions
  • Light-weight coil holders
