1、The lead screw accuracy of many sliding screws has reached the quality of
grinding screws, and with the right nut, it has greatly exceeded the
service life of ball screws.
2、From the automotive industry, medical
industry, aerospace industry and solar power devices, these cutting-edge
technologies, it is easy to see the sliding screw and its matching
Use
of engineering plastic nuts. More examples show that the sliding screw
is more suitable than the ball screw in many applications.
3、Although
the ball linear screw has high transmission efficiency, that is, higher load
capacity, but in some transmission power transmission capacity is
greater than the load, repeat
Positioning and reliability are more
critical, and sliding screw can be a good alternative while reducing
costs. In many cases, higher transmission efficiency is not applicable,
