***Following paragraph for cooling method: Water jacket
Machines with so-called water jacket cooling are to be filled with a mixture of water and glycol
with a minimum of 50% glycol. Instead of glycol, another similar liquid can be accepted. Make
sure that the liquid mixture tolerates the storage temperature without freezing. The liquid inlets
and outlets are to be closed after filling.
***Following chapter for bearing type: Rolling bearing
2.6.3 Rolling bearings
Apply the following measures:
• Rolling bearings should be well lubricated during storage. Acceptable grease types are
presented in Chapter 2.1.2 Bearing plate
• Turn the rotor 10 revolutions every three months to keep the bearings in good condition.
Remove any possible transport locking device during turning the rotor
• Machines may be provided with a locking device to protect the bearings against damage
during transport and storage. Check the bearing locking device periodically. Tighten the
transport locking device according to the axially locating bearing type, 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.
NOTE: The type of bearings used are found on the bearing plate, see Chapter 2.1.2 Bearing
plate, and axially locating bearing information from the dimension drawing.
