PMI GROUP was established in 1990. It’s highly involved in manufacturing
of ball screws, linear guideway, ball spline, actuator and cross roller
bearing. Its products are mainly applied to Machine Tools, Electric
Discharging Machines, Cutting Wire Machines, Plastic Injection Machines,
Semiconductor Equipment, and more.
Some key technologies include its “Cross Roller Bearing” and “Cooling
Nut System for Ball Screws”. The “Cross Roller Bearing” are compact
bearing with their rollers alternately crossed in a 90°v groove to each
other between inner and outer rings.
This design allows just one bearing to receive loads in all directions with
low deformation and extending its service life. The “Cooling Nut System
for Ball Screws”, by controlling the temperature rising from ball screws, it
reduces metallic deformations caused by heat and boosts the machine’s
axial motion velocity and accuracy.
Over the past 27 years, PMI has sold numerous quality precision
