Assembly.
Cautions 1):
Ball screw type
Before fixing the housing, it is necessary to align the slide bearing and the ball screw
axis.
Move the table to the opposite side of the motor as much as possible. And then,
tighten the screw (2).
∗ When they are misaligned, there will be vibration and noise while the actuator is in
operation.
Cautions 2):
Belt type
It is necessary to adjust the belt tension.
Refer to the Chapter 5 LEFB Belt Tension Adjustment.
Cautions 3):
Pull the dust seal band smoothing out the band with a finger from the motor side so
that there will be no deflection in the band, and then hold the band with a band
stopper.
For the replacement of the housing, order the part referring to the spare parts list in
the attachment.
