do not only depend on your skill, but also on
maintenance and servicing of the SBE. Insist
on using original spare parts when carrying
out maintenance and repair work. This ensures
operational safety and readiness of your SBE, and
maintains its value.

authorized service company.

maintenance work.
5.2.3
Securing Screws with Nord Lock washers
Nord Lock bolt securing systems use geometry to safely
lock bolted joints in the most critical applications. The
key is the difference in angles. Since the cam angle „
α
“
is larger than the thread pitch „
β
“, the pair of washers
expands more than the corresponding pitch of the thread.
Any attempt from the bolt/nut to rotate loose is blocked
by the wedge effect of the cams. When the pushed
movements of the equipment will get in contact with the
under surface of the securing plate, this surface contact
will secure the plate and prevents any motion in the axial
direction.
