For the reversed-home type actuator, the opposite side of the motor is the home position. The model
code is indicated with NM. Please contact us if a change in the home direction after delivery is required
since it requires adjustment of the movement direction parameter and also the encoder Z-phase
adjustment for some models.
(Characteristics)
(1) Low noise generation
Putting ball retainers removes the noise of metal balls crashing each other, and aligns the balls, thus
the harsh noise gets decreased.
(2) Smooth movement
A wear-off occurred by the friction of balls will be reduced, and run-out of the lubricant is avoided, and
also the lubricant stays on the retainer and supplies a smoother move.
8.2 Guide with Ball Retainer Mechanism
(Structure)
Putting spacers (ball retainers) between the balls will enable a lower operation noise and smoother
movement. Model code is indicated with RT.
