High Precision & Low Inertia: DL/DS Series Aluminum Diaphragm Couplings

The DL and DS Series are high-performance flexible couplings engineered specifically for motion control applications requiring rapid response and absolute precision. By combining lightweight high-strength aluminum alloy hubs with 304 stainless steel elastic diaphragms, these couplings provide high torsional stiffness and zero-backlash performance, making them the ideal link for modern servo and stepper motor systems.

Core Product Advantages

• Superior Material Synergy: Lightweight aluminum hubs reduce rotational inertia for high-speed operation, while imported 304 stainless steel discs ensure high torque capacity and long-term durability.

• High Torsional Rigidity: Designed to accurately control shaft rotation, allowing for micro-precision positioning in automated systems.

• Zero-Backlash Clamping: The secure clamp-screw fastening ensures a tight, gap-free connection between the shaft and hub, perfectly suited for frequent forward and reverse cycles.

• Excellent Misalignment Compensation: The stainless steel membranes effectively compensate for angular, axial, and parallel deviations, protecting motor bearings from premature wear.

• Identical Bi-directional Characteristics: Features identical rotation characteristics in both clockwise and counter-clockwise directions.

• H7 Precision Bore: Machined to strict H7 standards to ensure high concentricity and a perfect fit, reducing vibration and noise.
