Product Description
Large lead ball screw is mainly composed of screw, nut, ball and circulating device. The screw is a slender shaft with a spiral raceway, and the nut has a corresponding raceway inside, and the ball is located between the raceway of the screw and the nut. When the screw rotates, the ball rolls in the raceway and drives the nut to move in a straight line. The function of the circulating device is to enable the ball to cycle in the closed raceway to ensure the continuity of movement.
For example, just like a spiral track (lead screw) and a slider (nut) with a ball, when the track rotates, the slider moves quickly along the axis of the track, and the ball acts to reduce friction, similar to a small steel ball rolling between the track and the slider.

peculiarity
Lead is an important parameter of ball screw. The large lead means that with each turn of the screw, the nut moves up the screw axis by a larger distance. This makes it excellent in devices that require fast, linear motion.
For example, the lead of a normal ball screw may be 5mm, while the lead of a large ball screw may be 20mm or more. At the same speed, the large lead ball screw can achieve faster linear speed, and for some high-speed automation equipment, such as the arm movement of high-speed sorting robots, this feature can greatly improve work efficiency.
Product Display
Size specification
The "2020" in SFY2020 usually represents the nominal diameter and lead of the ball screw. The nominal diameter is 20mm and the lead is 20mm. The larger lead means that the nut moves a larger distance with each turn of the lead screw. This size specification makes it suitable for some equipment requiring fast linear motion.
accuracy level
The product generally has a variety of accuracy levels to choose from. For example, accuracy levels such as C3, C5 may be included. C3 precision is relatively high, suitable for equipment requiring strict positioning accuracy, such as precision machine tools, semiconductor manufacturing equipment, etc. C5 accuracy is slightly lower, but it can also play a good role in some occasions with high speed requirements and relatively less demanding accuracy requirements, such as material handling devices in automated production lines.
Load capacity
It has a certain axial load capacity. Through reasonable ball and raceway design, it can withstand large axial force. The specific load capacity depends on the screw material, the number and diameter of the ball and other factors. When designing the mechanical structure, it is necessary to select the right ball screw according to the actual working load to ensure that it will not be overloaded and damaged in long-term operation.
Transmission efficiency
Large lead ball screw SFY2020 has higher transmission efficiency. Because the ball is rolled between the screw and the nut, the friction coefficient is small, and the energy loss can be effectively reduced compared to the traditional trapezoidal screw. Its transmission efficiency can reach more than 90%, which makes it possible to achieve faster movement speed or withstand greater load when the drive motor power is certain.
Applicable environment
Generally suitable for a variety of working environments. If the appropriate protective measures and materials are used, it can work stably in a normal indoor industrial environment, where the temperature range is usually between -20 ° C and 80 ° C. However, in some special environments, such as high humidity and corrosive gases, special protection may be required, such as the use of stainless steel rods or the addition of protective sleeves to prevent rust and corrosion.
