***Following table for mounting type: Vertical
Table 2-2. Tightening torque for vertical machines (lubricated screw)
***Following chapter for bearing type: Sleeve bearing
2.6.4 Sleeve bearings
Apply the following measures:
•
Machines with sleeve bearings are delivered
without
lubricant
, i.e. oil. The inside of the
bearings should be checked for a protective oil layer. Tectyl 511 or other corresponding
substance should be sprayed into the bearing through the filling hole, if the storing period
is longer than two months. The corrosion protection treatment is repeated every six months
for a period of two years. If the storing period is longer than two years, the bearing has to
be taken apart and treated separately
•
The bearings should be opened, and all parts inspected after storage and before
commissioning. Any corrosion must be removed with a fine emery cloth. If the shaft has
left imprints on the lower liner-half, it must be replaced with a new one
•
Machines with sleeve bearings are provided with a transport locking device to protect the
bearings against damage during transport and storage. Check the transport locking device
periodically. Tighten the transport locking device according to the axially locating bearing,
see
Table 2-1 Tightening torque for horizontal machines (lubricated screw)
.
NOTE: A too high tightening torque on the transport locking device will damage the bearing.
