Overview
The Zero-Max SC040R is a ServoClass double flex coupling designed specifically for demanding servo motor applications. This flexible disc coupling accommodates higher torque, high speed and misalignment without premature failure due to fatigue or shock loads. The SC040R delivers 89 in-lbs operating torque, supports 10,000 RPM max speed, and provides 228 lbs/inch axial stiffness. The one-piece assembly and lightweight design make it ideal for precision servomotor applications.
Key Features
- Zero-backlash design: Field-proven ServoClass components ensure predictable, precise, zero-backlash performance.
- High torsional stiffness: Maintains precision positioning in servo control loops.
- Low runout and low inertia: Aluminum components and 304 stainless steel disc-packs provide strength and durability.
- Misalignment accommodation: Flexible disc design handles parallel, angular, and axial misalignment.
- RoHS-compliant: Eco-friendly design adapted to RoHS Directive with no banned substances.
