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.
