Keys are not included in the scope of delivery.
The design with shaft sealing ring is optional. The shaft sealing ring affects the
degree of protection chapter 4.2.6 "Degree of protection" on page 22. We rec-
ommend regular visual inspections on shaft sealing rings. Depending on ope-
rating conditions, signs of wear may appear after 5,000 operating hours. If nec-
essary, replace the shaft sealing rings.
Bosch Rexroth recommends to have these repairs made by Bosch
Rexroth Service.
Balancing
MS2N motors with keyway are balanced with "half key " (half key balancing acc.
to DIN ISO 21940-32).
The type of balancing is specified at the shaft front end or the base of the re-
cess with "H" for half key balancing.
