SFC SA2 DA2 Series Overview

The SFC SA2 DA2 series of encoder couplings features a disc-spring design that combines high torsional stiffness with exceptional response characteristics. The lightweight, high-strength aluminum alloy clamp hub ensures secure shaft mounting while minimizing moment of inertia — critical for high-speed encoder applications where rapid acceleration and deceleration are required.

These couplings are available in both single-element types (offering high torsional stiffness) and double-element types (which separate double elements with a spacer for additional flexibility). Both configurations lower the moment of inertia by linking the outer diameter of the hub to the shaft diameter, optimizing performance for encoder and stepper drive applications.

With zero backlash and maintenance-free operation, the SFC SA2 DA2 series is the ideal choice for precision motion control systems requiring accurate position feedback and reliable torque transmission.

Key Features

Disc-Spring Design
