This design then has the plastic wipers clear the threads, while the felt wipers lubricate. elastomer, and they are constructed in such a way as to generate friction.

 

A ball screw assembly is usually fairly simple although they do have a number of small components. The friction will help the wipers collect any dust that is brushed by them. A primary cause of the efficiency levels of ball screw assemblies is that they do not suffer from significant frictional effects.

Unfortunately ball screw assemblies can be affected by any miniscule pieces of dirt.

Wiper systems usually consist of tiny brushes which move across the threads of the ball screw nut, basically picking up any obstructions. There is of course a selection of wiper designs available to ball screw designers. Take as an example the end cap return ball nut, which makes use of a small cap added to the base of the ball screw nut. When everything is in order, the ball screw should work without any difficulties, as the various components move through the system. If it happens that small pieces of dust or dirt become fixed inside the ball screw nut, this will obstruct the movement of the ball bearings. The majority of wipers are manufactured from plastic, i. Felt, brush or elastomer is common components of these wipers.There are quite a few designs for ball screw recirculation systems to choose from.
.

Wipers are useful to help improve the lifespan of a ball screw, and Transparent Plastic Ball are most effective if the ball screw has the correct degree of maintenance. Some wipers also contain an additional felt wiper, which is used to lubricate the interior of the ball screw nut with either oil or grease. Any blockage in the interior of the ball screw assembly will reduce the smoothness, raising the levels of friction and lowering the efficiency of the apparatus.e. Every design has a primary function however, that is to collect any items of dust that have made their way inside the ball screw assembly
