Rigid Sleeve Couplings
Rigid sleeve couplings connect shafts without a resilient element.
Rigid sleeve couplings connect shafts without a resilient element. They are used where the shafts can be aligned accurately and the machine does not require coupling flexibility.
Supporting Coupling Type: NM flexible couplings are the primary product range from EVER POWER. This product is offered for applications that require its specific construction.
When to consider this product
Choose a rigid coupling when the system design specifically requires a rigid shaft connection and alignment can be controlled closely during installation and service.
RFQ information

| Bores | Both shaft diameters, keys and fits. |
| Sleeve dimensions | Available length and outside-diameter limits. |
| Duty | Torque, speed and machine function. |
How it differs from an NM coupling
An NM coupling adds an elastomeric element between hubs; a rigid sleeve does not. The two types address different alignment and vibration needs.
