12.4.3
Re-lubrication of the hybrid bearings
The average continuous speed determines the service life or the interval
length until the required re-lubrication. However, the number of re-lubrications
is limited due to the size of the grease collecting chambers on the bearings.
A lubrication nipple is located on both sides of the energy storage device for
re-lubrication of the bearings (see
). In order to ensure that no con‐
tamination penetrates into the contact zones of the bearing, the lubrication
nipples must be cleaned before each use at all costs.
●
The amount of lubricating grease per re-lubrication must be
between 22 and 25 g.
Before re-lubrication, determine with which stroke rate the
used grease gun reaches the permitted grease quantity in
order not to exceed this quantity.
●
The grease must be pumped in slowly and carefully during
operation at a low speed of ≤ 100 rpm so that the bearing is
not overheated due to re-lubrication.
●
Re-lubrication of the bearings must only be carried out 4
times.
●
If the end of the available operating hours (see
) of the last re-lubrication interval has
been reached, no further re-lubrication may be carried out.
In this case, remanufacturing must be carried out by Bosch
Rexroth.

Further data on re-lubrication, e.g. the permitted grease, can be found on a
re-lubrication instruction sign next to the lubrication nipples on the energy
storage device.
