Screw Fasteners
Certain unions are screwed into the goods with a
through screw and a lock nut.The thread in the
goods is intended to take the effective torque and
the lock nut is to secure the union during use.
Therefore, the main part of the torque - screw in the
goods - should always be tightened first and then
secured with the lock nut, which is tightened with
less torque. If the lock nut is tightened with too high a
torque, the screw in the goods thread will be
unstressed and the bolt fastening will come loose
during use.

start to move on the pin.This will cause much
wear on the pin.
• There is a risk of overloading the screw when
operating if it is tightened too hard.
1. Lubricate the bearing seatings and studs with
corrosion inhibiting grease.
IMPORTANT!
Only press the outer race when driving in the bearing.
