Lubricating using the regreasing system
A flat grease nipple in accordance with DIN 3404, size M10x1, is provided at both the DE ①
and the NDE ② for regreasing.
1. Clean the grease nipples at the DE and NDE.
2. Press in the type and quantity of grease specified (see lubrication instruction plate). The
shaft rotates so that the new grease is evenly distributed throughout the bearing.
The bearing temperature initially increases noticeably. After the excess grease has been
displaced out of the bearing, the temperature will return to the normal value.

9.2.6.5 Cleaning the spent grease chamber
The rolling-contact bearing's spent grease chamber only has room for a limited amount of
spent grease. When the spent grease chamber is full, the spent grease must be removed,
otherwise it will penetrate into the interior of the machine. The information on the amount of
grease to be used when regreasing can be found on the lubricant plate. When changing the
bearings remove the spent grease that has collected in the spent grease chamber and in the
outer bearing cover.
