SFY50100 7.938mm Milled Mute Self Lubricating Heavy Duty Ball Screw
The ZLV SFY50100 7.938mm Milled Mute Self Lubricating Heavy Duty Ball Screw is a mechanical linear actuator that translates rotational motion to linear motion with high precision and efficiency. It’s meticulously designed for heavy duty applications that demand high performance, robustness, and longevity. This ZLV model ball screw, with a shaft diameter of 50mm and a lead of 50mm, comes with a unique blend of features that make it suitable for a wide range of applications including industrial machinery, robotics, and automation systems.
Characteristics
- Low Friction Loss, High Transmission Efficiency: Due to the rolling motion between the screw shaft and the screw nut, a high transmission efficiency can be achieved. Compared to the traditional sliding screw pair, the driving torque is less than 1/3, which is very helpful in energy saving.
- High Precision: The ball screw pair is generally produced coherently with the world’s highest level of mechanical equipment, especially in the aspects of grinding, assembly, and inspection processes.
- High Speed Feed and Micro Feed Possible: Because the ball screw is utilizing ball movement, the starting torque is very small, which can ensure precise micro feeding.
- High Axial Rigidity: The ball screw can be pre-loaded, and the axial gap can be negative due to the preload, thereby obtaining higher rigidity.
- Reversible Transmission: Unlike traditional screw systems that can lock under certain conditions, ball screws do not lock and offer smooth, reliable operation in both directions.

Composition and Classification
The ball screw is composed of a screw, a nut, a steel ball, a pre-pressure piece, a reverser, and a dust protector.
Classification:
- Self-Lubricating Ball Screw: This ball screw does not require a lubrication pipeline system and equipment, reducing the cost of oil replacement and waste oil treatment.
- Mute Ball Screw: It can suppress the noise generated by the collision between the balls during operation, making the ball screw run more quietly and smoothly.
- High-Speed Ball Screw: Features high acceleration, high rigidity, high-speed feed, low vibration, and low noise.
- Heavy-Duty Ball Screw: Able to withstand larger axial loads, suitable for fully electric design machines, air compressors, semiconductor manufacturing devices, and forging manufacturing devices.
Length:In terms of length, there are two concepts: overall length and thread length. Some manufacturers only calculate the overall length, but some manufacturers need to provide the thread length.
Nut Form:The product sample of each manufacturer will have many nut forms, and the first few letters in the general model represent the nut form.
Accuracy:According to domestic classification, the accuracy level of ball screws has P1, P2, P3, P4, P5, P7, P10, and so on.
In summary, the ZLV SFY50100 7.938mm Milled Mute Self Lubricating Heavy Duty Ball Screw brings together precision, efficiency, and strength. Its unique attributes make it an indispensable asset in the fields that demand high performance, and durability. With the assurance of high-end customization, the ZLV SFY50100 ensures a perfect fit for your application.
