Notes on assembling
When mounting the coil spring in the bear-
ing holder, set the position of the spring
bending section

as follows. Insert the
end of the bending section between the
ball bearing flange

and the bearing
holder.
Since the end of the bending section
touches the outer area of the ball bearing,
static electricity on the roller is discharged
to the side plate.
