Ballscrew Repair
ERIKS specialises in the service and repair of recirculating ballscrews.
Following the same proceedings as the spindles, the ballscrews are repaired in a specifically dedicated workshop, by qualified technicians. According to the state of wear, the ballscrew and / or the nut may be re-ground. When the state of the ballscrew does not allow a repair, we propose the fabrication of a new ballscrew, strictly interchangeable with the received one.
On receipt of your ballscrew, our engineers will:
- Photograph the unit for record of nut orientation and other features that maybe removed during assessment
- Your unit will be fully stripped to asses the condition of; the shaft and nut raceways, ball transfer devices and wipers. The condition of end journals and locknut threads will be recorded
- After our engineer has completed the assessment, we will send you a report on the condition of your unit. Also, you will receive the options available to get your ballscrew to a serviceable condition and prices for the respective options; this will be done within 24 hours of receipt of your ballscrew
Standard repair options
Option 1: Refurbishment and re-ball
This involves all the components being thoroughly cleaned; the shaft is checked for straightness and re-straightened if necessary. Any damage to journals and threads is repaired and the whole shaft is then polished. The unit is then rebuilt and the correct preload torque is set.
We have an extensive range of over 50 million ball bearings in grade 5 and grade 10 precision that cover both imperial and metric sizes.
Option 2: Regrind shaft and new nut
If the ballscrew has suffered fatigue damage in the balltrack, our next option is then to regrind the shaft and manufacture new nut.
We are able to repair all makes and designs of ballscrews; ground ballscrews, rolled ballscrews and all designs of high speed ballscrews.
Our equipment and ball range enables us to repair all sizes of ballscrew, from miniature ballscrews to units that are up to 120mm diameter and 7m in length
