1)
Grease quantity for re-lubrication, normal conditions.
2)
Quantity of grease that can be injected into the grease chamber when precisely maintaining the quantity of grease for
each re-lubrication interval.
3)
Calculated number of re-lubricating intervals; the bearing lifetime is specified according to statistical perspectives in
accordance with the L
10h
definition.
NOTICE
Unfavorable factors such as the effects of mounting/installation, speed or mechanical loads
require that the re-lubricating intervals are appropriately adapted. Situations such as these
require special consideration or must be be calculated - and must be engineered according
to the limitations and constraints together with the responsible motor plant.
