How can I protect a ball screw assembly from dirt?

Keeping foreign debris out of a ball nut is important to ensure it runs smoothly and lasts as long as possible. Most sizes of ball nuts are available with wipers. Some wipers are integral to the nut itself while some are held in place against the flange with external fixtures.  The catalog lists the wiper options available for each particular nut.

Additionally some customers will add bellows or telescoping covers from vendors that specializes in those type of covers. Thomson does not offer bellows for our ball screws.
