Overview
The EAC-1250-F self aligning coupler from E&E Special Products is engineered for pneumatic and hydraulic cylinder applications requiring precise yet flexible shaft alignment. This coupler eliminates expensive precision machining for mounting fixed or rigid guide in cylinder for slide applications. It compensates for 2° angular error and 1/16 lateral misalignment compensation on push and pull stroke, enabling seamless installation without rigorous alignment procedures.
Key Features
- Increases cylinder efficiency by eliminating friction caused by misalignment
- Greater reliability and reduces cylinder component wear
- Self aligning couplers simplify alignment problems by being able to adjust them in the field
- Designed for both push and pull stroke applications
- Sturdy 1-1/4″ bore construction for industrial duty
