At Ewellix, we support our customers in planning and assembling their systems with optional accessories for nuts and ball screws.
A special range of support bearings has been developed for ball screws with a nominal diameter from 16 mm and for roller screws.
These support bearings can be easily installed at the ends of the spindle in accordance with Ewellix recommendations.
All models are equipped with high quality SKF bearings, lubricated and sealed for life. Ewellix keeps these support bearings in stock at all times so that fast delivery is possible.
