A 1-1/4" shaft coupling without keyway is a mechanical coupling used to connect two rotating shafts while transmitting torque without relying on a traditional keyed connection. These couplings typically use a plain bore with set screws, clamping, or friction-fit methods to secure the shaft.
Product Data
A typical 1-1/4" no-keyway rigid coupling may have:
Bore: 1.25"
Length: approximately 4-1/2"
Outside diameter: approximately 2-1/8"
Material: Mild steel
Plain/no-keyway bore design
Features
No machining required for keyway alignment
Simple shaft-to-shaft connection
Suitable for applications where shaft alignment is maintained
Provides a compact rigid connection
Available in rigid sleeve, clamp, and flexible coupling designs
