Highlights
Ball retainer
The ball retainer is used, which reduces collision of steel balls during high-speed movement, effectively reduces torque fluctuation, and improves sound quality.
Circulation design with high d•n value
Steel balls move smoothly along the helical line of the screw shaft, reducing the shock of the steel balls on the circulating part. The d•n value (shaft diameter x speed), which is used as a high-speed performance evaluation index of ball screws, is increased to more than twice that of the previous bobbin insertion circulation mode.

High sealing performance
A sealing ring with high sealing performance can effectively prevent splash of lubricating grease, so that lubricating grease retention is greatly improved. The unique sealing structure fits more closely to the spiral track surface of the screw shaft, significantly improving dust-protected and grease retention capabilities.

High lead design
The high-load series of ball screws from LAIEN can achieve ultra-high leads (the ratio of the shaft diameter to the lead is 1:1) and high d•n values, enabling a high-speed feed.
Noise reduction design
Allowing steel balls to move smoothly along the helical line of the groove can reduce the shock of the circulating part on steel balls and the noise level of ball screws during operation.
