Description
The difference between a single disc coupling and a double disc coupling is that the single disc coupling doesn’t accommodate parallel misalignment and will absorb fewer misalignments than a double disc coupling. However, the double-disc coupling can absorb more misalignments, including a parallel misalignment due to its dual discs.
Single Disc Coupling Features
- High precision, designed for servo, stepping motor design.
- Seamless connection shaft and sleeve. Suitable for forwarding reverse.
- Low inertia, suitable for high speed.
- Shrapnel is made of stainless steel, which has excellent fatigue resistance.
- Clamp type.
