Ballscrew (Ground)

Ball screws that have been formed by a grinding process are used where acute linear accuracy is paramount within the application. We offer a quality program of metric threaded screws, with a variety of ball nut combinations.

In March 2008 we have launched a new end deflection series, which recirculates the ball bearings in the end plate of the ball nut. This design not only reduces the length of the ball nut but reduces the cost as well. The new FEB and FDB series are available in diameters of 6, 8, 10 and 12mm with leads ranging from 2.5 to 10mm. As standard this new series offers up to C3 lead accuracy and a full end machining capability. (please see pictures on right hand side of page)

A full end machining capability allows us to supply ready to fit linear designs without you having to worry about scrap rates. We also welcome the chance to develop linear solutions with the application engineer to achieve bespoke designs within tight cost budgets.

Key advantages to ground ball screws are;

  • Precision Ground C0-0 to C5-50 accuracy versions
  • 4mm diameter through to 14mm diameter products
  • Wide selection of leads available
  • Zero axial clearance products
  • Flanged and cylindrical ball nut designs
  • Full journal end machining capability (machining)
  • Ball screws integrated with bearings and NEMA mounts (bearings)
  • ISO9001 approved
