Types And Quantities Of Grease For High-Speed Machines - Siemens SIMOTICS 1PQ8 Operating Instructions Manual

Regreasing roller bearings
Pay attention to the instructions on the lubricant plate.
1. Rotate the shaft when regreasing, so that the new grease can be distributed throughout
2. Clean the grease nipple before regreasing. Gradually press in an appropriate type and
3. The used grease collects outside each bearing in a spent grease chamber.
Lubricating roller bearings prior to commissioning
When properly stored prior to commissioning for a longer period of time, normally the grease
in the bearings does not deteriorate within two years. Please note the information regarding
long-term storage.
When commissioning, the bearings must be relubricated with twice the amount of lubricating
grease. When doing this, the shaft must rotate so that the grease is replaced in the bearings.
Overheating of the rolling bearings
If the roller bearings are not regularly regreased, local overheating may be possible, and, as
a consequence, an explosion in an explosive atmosphere. This can result in death, serious
injury or material damage.
● Regrease the roller bearings regularly according to the lubrication plate.
● Implement bearing temperature monitoring if not yet in existence.

Types and quantities of grease for high-speed machines

For high-speed machines, only the types of grease specified on the lubricant plate are
permitted. The following grease types have been tested and are suitable.

Motors that are operated with converters: Regrease the bearings at a low to medium speed
(n = 250 rpm, n = 3600 rpm) to ensure an even distribution of grease.

WARNING
Rotating components
The shaft must rotate to allow the grease to be distributed. This can result in death, serious
injury or material damage.
● When regreasing, pay attention to all rotating components.

instructions.
The roller bearing temperature rises sharply at first, then drops to the normal value again
when the excess grease is displaced out of the bearing.
