Oldham coupling KSK
Excellent damping characteristics and absolute backlash-free operations are the main features of the KSK coupling. Due to the different hub designs there are multiple ways of connection.
- 1.5 to 7 Nm
- Zero Backlash
- High flexibility
- Hubs in different adaptions available
- Bores up to 16 mm
