2.1 Protective measures prior to transport

2.1.1 General

***Following bullet for bearing type: Rolling bearing
***Following bullet for bearing type: Sleeve bearing
***Following bullet for cooling method: Air-to-water

2.1.2 Bearing plate

6 - Transport and Unpacking
The following protective measures are taken before delivery of the machine from the factory.
The same protective measures should be taken, whenever the machine is moved:
• Some machines, and all machines with sleeve or roller bearings, have transport locking
devices installed
• Ball and roller bearings are greased with lubricant indicated on the bearing plate, which is
attached to the machine frame, see Chapter 2.1.2 Bearing plate
• Sleeve bearings are flooded with oil and drained. All oil in- and outlets, as well as oil tubes
are plugged. This gives sufficient protection against corrosion
• Air-to-water coolers are drained and the cooler in- and outlets are plugged
• Machined metal surfaces, such as the shaft extension, are protected against corrosion with
an anti-corrosive coating
• In order to protect the machine properly against water, salt spray, moisture, rust and
vibration damages during loading, sea transport and unloading of the machine, the
machine should be delivered in a seaworthy package.
A stainless steel bearing plate is attached to the machine frame. For the location of the bearing
plate, see Appendix Typical position of plates.
The bearing plate indicates the type of the bearings and lubrication to be used, see Figure 2-1
Bearing plate for grease lubricated rolling bearings and Figure 2-2 Bearing plate for sleeve
bearings.
