Backlash Adjustment
Backlash is the amount of play in a leadscrew. it
is felt when turning a handwheel in one direction,
then turning it in the other direction. the distance
that the handwheel moves without moving the
leadscrew or components is the backlash.
When adjusting backlash, tighten the compo-
nents enough to remove excessive backlash,
but not so much that the components bind the
leadscrew, making it hard to turn. overtightening
will cause excessive wear to the sliding block and
leadscrew.
