We’re the ballscrew specialists, providing replacements, repairs, upgrades and more.

Ballscrew Repairs and Replacement

Ballscrew Upgrade

Once a ballscrew is beyond economical repair a like for like replacement can be supplied or in most cases, we can look at the application and the parameters to determine whether an upgrade is feasible. Any upgrade would include the use of larger balls, more contact balls or ceramic balls and surface treatment to the raceways. The advantages are numerous (less lubrication, harder raceways, lower torque, less vibration, less noise) all resulting in the benefit of a significant increase in operating life of the ballscrew, by a minimum of 35%.

Whilst the unit price of the upgraded ballscrew will be high compared to a like-for-like replacement, the benefit of extended life will outweigh the cost through increased productivity and less application downtime.
