Regreasing
While regreasing, the shaft must rotate so that the new grease is evenly distributed throughout
the bearing. For motors that are be operated with a converter, regreasing should be carried
out at low-to-medium speeds (n
min
= 250 rpm, n
max
= 3600 rpm) to ensure an even distribution
of grease. This ensures adequate even lubrication.
WARNING
Rotating parts
When regreasing, pay attention to all rotating components. This can result in death, serious
injury or material damage.
1. Clean the grease nipple before regreasing. Gradually press in an appropriate type and
amount of grease, as stamped on the lubricant plate and specified in these operating
instructions.
The roller bearing temperature initially increases noticeably. After the excess grease has
been displaced out of the bearing, the temperature will return to the normal value.
The used grease collects outside each bearing in a spent grease chamber.
