High-Speed Balancing of Aviation Drive Shafts
Types R-50.1HS and R-150.1HS
The Hofmann balancing machines R-50.1HS und R-150.1HS are used to balance drive shafts from aviation engines or aviation drive systems at high speeds. These drive shafts generally show flexible behavior, so they should be balanced at operating speed and checked for runout.
