Notes
•
When the screws are greased, the friction coefficient µ can be reduced by as
much as half. As the tightening torques required to reach the maximum
permissible tightening force depend on the friction coefficient, they must be
reduced accordingly. The values can be obtained from the screw
manufacturer’s information or from the specialist literature. If necessary, carry
out tests to determine the actual friction coefficient.
•
Refer to the screw manufacturer’s information. This is always binding.

DIN 51825.
•
When greasing the carriage, move it by three times its length.
