Slide Ways
Slide ways are non-recirculating linear motion bearings utilizing precision rollers. With high precision and high rigidity, it can handle loads and moments in all directions.
Slide Bushings
This high precision bearing has smooth and endless linear motion.
Slide Units
Low friction linear motion mechanism.
Slide Shafts
These shafts can be used for guiding the ball bearings and other components to create highly accurate linear movements without complications.
30 Degrees Trapezoid Feed Screws
This feed screw is used for linear motion of machine tool parts. The male threads are manufactured with precision rolling machines, which provide low wear and long life.
Precision Planetary Roller Screws
The planetary mechanism controls the movement and rotation of the rollers, allowing for accurate operation even in adverse environments.
Precision Recirculating Roller Screws
High load rating and high rigidity are achieved with small leads (e.g., 1 mm), which is not possible with conventional screws.
