5.6.3 Radial shaft seal rings
Leak-proofness
Our gear units are equipped with high-quality radial shaft seal rings and checked for leaks. However, a leak
cannot be fully ruled out over the length of use of a gear unit. If you use a gear unit with goods incompatible
with the lubricant, you must take measures to prevent direct contact with the gear unit lubricant in case of a
leak.
5.6.4 Oil expansion tank
The gear units have a higher fill level in mounting position EL5. The oil expansion tank prevents oil from es-
caping out of the gear unit.
Notes
• We recommend using an oil expansion tank in mounting position EL5 (additional cost) for fast running
gear units with an input speed n
1
> 1750 rpm and gear ratios i < 20.
• It is not possible to use an oil expansion tank if the plug connector is at 90°!
