Dirty or used clamping sets have to be disassembled and cleaned before assembly. After-
wards the taper surfaces and threads have to be lubricated with Molykote MoS
2
(see illustra-
tion 4). For re-lubrication please use the multi-purpose grease Molykote G Rapid plus, as an
example.
!
If hexagon screws with Geomet coating are used, the tappings of the external ring and the
hexagon screws must not be lubricated with Molykote.
!
Please inspect the taper surfaces of the clamping set for the lubrication specified.
•
Please inspect shaft and hub fit for the tolerance specified (h6/H7 bzw. > Ø160
– g6/H7).
•
The contact surfaces of hub/hollow shaft inside and the shaft have to be cleaned and degreased.
!
The contact surfaces of shaft and hub bore (hollow
shaft inside) must neither be lubricated nor oiled (see
illustration 4).
!
If hexagon screws with Geomet coating are used, the
tappings of the external ring and the hexagon screws
must not be lubricated with Molykote.
