DI Type (Drop-In Spacer) Coupling Additional Resources
The DI Type coupling consists of:
- Two – Hubs
- One – Spacer Assembly
- 2 – Disc Pack Kits
Custom spacer lengths can be specified for special applications.
The coupling has two flex planes (one at each disc pack) so it can accommodate parallel misalignment by the angular misalignment in each disc pack. This configuration will also accommodate axial misalignment within the specified limits.
