Combination Wiper

As cutting speeds increase, so do component lifetime requirements. This two-stage wiper cleans and lubricates to extend ball screw life.

Problem: Precision-ground ball screws designed for 300 to 400 million revolutions once ensured long life. Today, high-speed cutting machines can reach those numbers within a year, and need added protection from adhesive and abrasive wear.

Solution: Segmented plastic wipers, in combination with a continuous felt ring. During operation, pre-loaded finger-type seals clean the shaft, guiding abrasive contaminants away via beveled edges. A liquid lubricant, oil, or grease - stored and distributed by the felt ring - protects against the adhesive effects of micro-welding.
