Overview
The Zero-Max SC040R-041-019 servo coupling is part of the ServoClass double flex coupling line, designed to deliver smooth torque transmission in precision industrial automation systems. The 041-019 bore configuration accommodates mixed shaft diameters, making it suitable for servo motor retrofit and OEM applications. Built with dual flex elements, this coupling minimizes backlash while absorbing minor misalignment common in servo-driven systems.
Key Features
- Double flex design: Stainless steel flex elements for corrosion resistance and consistent performance
- High-speed rated: 10,000 RPM maximum operating speed supports modern servo motors
- Low backlash: Precision-engineered for accurate positioning in motion control applications
- Misalignment tolerance: Accommodates angular, parallel, and axial shaft misalignment
- Clamp-style assembly: M4.0 screw design for secure, repeatable assembly per Zero-Max installation standards
