All shafts are mounted in rolling bearings.

Shaft seals

Depending on requirements, radial shaft­sealing rings or Taconite seals are fitted at the shaft exits to
prevent oil from leaking from the housing and dirt from entering it.
5.7.1 Radial shaft­sealing rings
Radial shaft­sealing rings are the standard type of seal. They are fitted with an additional dust lip to protect
the actual sealing lip from external contamination.
For special mounting positions the radial shaft­sealing ring is used with a grease filling
in combination with a ring.
Where large quantities of dust occur as specified by the requirements in
Directive 94/9/EC, use is provided only in combination with the Taconite seal
(see item 5.7.2).
