• MOQ: 1 Set (Custom flange dimensions & non-standard sizes supported)

2. Key Features & Technical Advantages

Why Choose Apex SWC-WD Cardan Shaft Couplings?

1. Ultra-Compact Short Design: The WD series eliminates the spline sliding section, resulting in an exceptionally short axial length for high-torque power transfer in tight machine layouts.

2. High-Strength Forged Steel Construction: Manufactured with premium forged steel hubs and high-grade bearing steel cross spiders to handle severe peak shock loads and continuous operation.

3. High Torque & Large Angular Offset: Capable of transmitting nominal torques up to 1,000 kN·m with dynamic angular flexibility between 15° and 25°.

4. Convenient Flange Mount Assembly: Precision-machined standard flange bolt connection ensures rapid installation, precise axial alignment, and low maintenance downtime.

5. Smooth Operation & High Efficiency: Delivers optimal rotational stability and maximum drive efficiency under bidirectional starting and reversing conditions.
