Good quality diameter 12mm miniature ball screw

12mm Diameter Miniature Ball Screw with factory price for CNC machine

Ball screw pairs and other rolling friction transmission elements can be considered to work with almost no wear as long as the entry of abrasive particles and chemically active substances is avoided. However, if dirt falls on the raceway, or dirty lubricating oil is used, it will not only prevent the normal operation of the balls, but also increase the wear rapidly.
Usually, a felt ring is used to seal the nut pair. The thickness of the felt ring is 2 to 3 times of the pitch, and the inner hole is made into the shape of a thread, so that it tightly wraps the lead screw and fits into the grooves at both ends of the nut or sleeve. inside the hole. In addition to soft felt, the sealing ring can also be made of oil-resistant rubber or nylon. Since the sealing ring and the screw are in direct contact, the dustproof effect is better, but the frictional resistance torque of the ball screw nut pair is also increased. In order to avoid this frictional resistance torque, a non-contact labyrinth seal made of hard plastic can be used, and the inner hole is made in the opposite shape to the screw thread raceway, and there is a certain gap.
