SFU1204 SFU1204-L215.5mm rolled ball screw

The ball screw is composed of a screw, a nut, steel balls, pre-pressing plates, a reverse device, and a dust cover. Its main function is to convert rotational motion into linear motion, or to convert torque into axial repetitive forces. It also has the characteristics of high precision, reversibility, and high efficiency. Due to its very low friction resistance, the ball screw is widely used in various industrial equipment and precision instruments.

Type:

There are two common types of circulation methods: external circulation and internal circulation. When the ball is sometimes disengaged from the screw during the circulation process, it is called external circulation; when it always remains in contact with the screw, it is called internal circulation. Each closed circuit of the ball in every circulation is called a row, and the number of pitches contained in each row of the ball circulation closed circuit is called the number of turns. For the internal circulation ball screw pair, each nut has 2 rows, 3 rows, 4 rows, 5 rows, etc., and each row has only one turn; for the external circulation, each row has 1.5 turns, 2.5 turns, and 3.5 turns, etc.


Features:

1. Low friction loss and high transmission efficiency

2. High precision

3. Capable of high-speed feed and micro-feed

4. High axial stiffness

5. Cannot self-lock and has reversible transmission capability
