Characteristics

  1. Low Friction Loss & High Transmission Efficiency: With multiple steel balls performing the rolling motion between the screw shaft and nut, the SFU1204 Ball Screw achieves high transmission efficiency, reducing the required driving torque to less than a third compared to sliding screw pairs.
  2. High Precision: Manufactured with top-tier mechanical equipment, under strictly controlled environments in terms of temperature and humidity, the product ensures outstanding precision.
  3. High-Speed Feed & Micro Feed: The rolling motion of the steel balls allows for a minimum startup torque, preventing crawling phenomena seen in sliding motion, and ensuring precise micro feed.
  4. High Axial Rigidity: The application of preload allows the axial gap to reach negative values, leading to high rigidity. This is achieved by exerting pressure on the steel balls, enhancing the rigidity of the nut part in practical applications.
  5. Non-self-locking & Reversibility in Transmission: This ball screw does not have a self-locking feature and offers reversibility in transmission.

Composition and Classification

The SFU1204 Ball Screw comprises the screw, nut, steel balls, pre-press plate, reverser, and dust preventer. Ball screws can be classified into:

  1. Self-lubricating Ball Screw: This type has a detachable oil remover, eliminating the need for a lubrication pipeline system and equipment, reducing oil change and waste oil handling costs.
  2. Silent Ball Screw: This design suppresses the noise generated by collisions between steel balls during motion, resulting in smoother and quieter operations.
  3. High-speed Ball Screw: This variant is characterized by high acceleration, high rigidity, high-speed feed, low vibration, and low noise, making it suitable for fast-feeding machine tools, high-speed cutting center machines, and high-speed vertical load cutting centers.
  4. Heavy Load Ball Screw: It can bear larger axial loads, suitable for full-electric design machines, pneumatic machines, semiconductor manufacturing devices, and forging manufacturing devices. There’s a distinction between rolled and ground screws. Rolled screws have slightly lower precision and are suitable for occasions where precision requirements are not very high. In contrast, ground screws have higher precision and are suitable for high-precision occasions.

Parameters

  1. Nominal Diameter: The nominal diameter refers to the outer diameter of the screw. Common specifications include 12, 14, 16, 20, 25, 32, 40, 50, 63, 80, 100, 120 mm.
  2. Lead: The lead refers to the distance the nut moves in a straight line when the screw rotates one round. Common leads include 2, 4, 5, 6, 8, 10, 16, 20, 25, 32, 40 mm. The lead is related to the movement speed of the nut and the linear thrust the ball screw can provide.The relationship between the lead and the screw thrust is as follows: F=(2*π*T*n)/i F: Screw thrust (N) T: Torque provided by the motor (N·m) n: Transmission efficiency (The transmission efficiency of ball screws is usually 85%-95%) i: Lead (m)
  3. Length: Length has two concepts, overall length and thread length. Some manufacturers only calculate the overall length, but some manufacturers require providing the thread length. Thread length also includes two parts, thread total length and effective stroke.
  4. Nut Type: Many nut types are available and are generally indicated by the first few letters in the model number. By flange type, there are round flange, single-cut flange, double-cut flange, and no flange. By nut length, there are single nut and double nut.
  5. Accuracy: Ball screws, according to domestic classification, have accuracy levels of P1, P2, P3, P4, P5, P7, P10.
