RFY Series
RFY Series
RFY series ball screw is a high-precision, high-efficiency transmission element, widely used in CNC machine tools, automation equipment, robots and other industrial fields. Its main function is to convert rotary motion into linear motion. In many occasions that require high-precision position control and high-speed motion, ball screws are indispensable components.
RFY series ball screws can provide up to C5 or C7 grade accuracy, suitable for applications with high positioning accuracy requirements.

Safe use process
-
Lubrication
Lubrication significantly reduces friction, reduces wear and ensures smooth operation.
-
Dustproof
Use protective devices (foldable or telescopic screw covers) to completely protect the screw shaft to prevent dirt and foreign matter (chips and debris) from entering.
-
Using
Prevent reverse rotation; prevent the nut from coming out
-
Installation
When the nut must be removed, use an auxiliary sleeve that is 0.2 to 0.3 mm smaller than the bottom diameter of the screw.
