LINEAR BEARINGS
If the pressure bar has substantial play or slop
in it while moving it up and down, the linear
bearings are worn and need replacement.
Also, inspect the rails to ensure the bearing
surface is smooth and free of wear. Surface
imperfections indicate bearing wear.
The linear guide bearings are adjustment free.
Note: Sharp Packaging Systems recommends
changing the linear guide bearings in pairs for best
results.
