The design with shaft sealing ring is optional. The shaft sealing ring affects the
degree of protection
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.
