Roller Ball Screw

Description

Feature of rotating nut ball screw: High efficiency of transferring, clean movement, high precision, duration, reliability, no hole and preloading, low friction, prolonged lasting layout and high-speed operation.

Product Details

Ball screw pair and different transmission components of rolling friction can be regarded to work almost without wear as long as abrasive particles and chemically energetic substances are avoided. But if you fall into dirt in the raceway, or use soiled lubricating oil, it will now not only hinder the everyday operation of the ball, but also make the put on enlarge sharply.

Usually, felt ring is used to seal the nut pair. The thickness of felt ring is 2 ~ 3 times of the pitch, and the inner hole is made into the structure of thread, so that it tightly wraps the lead screw and is loaded into the slot at each ends of the nut or sleeve. In addition to smooth felt, the sealing ring can be made of oil-resistant rubber or nylon material. Due to the direct contact between the seal ring and the lead screw, the dust-proof effect is better, but also increases the friction resistance 2nd of the ball lead screw nut pair. In order to avoid this friction-resistance moment, a non-contact labyrinth sealing ring made of harder plastic can be used, with the inner hole shaped in the opposite shape to the lead screw thread raceway and with a sure gap.

Product Description

The rotating nut ball screw is a high-efficiency feed screw with the ball making a rolling action between the screw axis and the nut. Compared with a conventional sliding screw, this product has pushed torque of one-third or less, making it most suitable for saving force motor power. The advantages of ball screw transmission: high transmission accuracy, easy movement and no creeping phenomenon. The ball screw pressure is basically rolling friction, and the friction resistance is small. The friction resistance has almost nothing to do with the tempo of movement.
