Ball-screw combination wiper

A combination wiper, in sizes 16 to 80 mm, is available for the company's precision ball screws.

The plastic wipers consist of a friction-type finger wiper in front of a felt wiper (that's saturated with oil or grease) that keeps contaminants from entering the ball nut while simultaneously lubricating the ball screw. The wipers conform to the thread profile for dual wiping action. Only a small amount of oil is deposited on the thread, reducing ball-screw oil consumption. The wipers are available in the following sizes: 32 x 15, 40 x 20, 50 x 20, and 63 x 20.
