DPG Series High-Precision Flexible Jaw Spider Coupling

Aluminum Alloy & S45C Steel Clamping Hub Coupling for Power Transmission

The DPG Series Flexible Jaw Spider Coupling is a high-performance power transmission component featuring advanced clamping hubs and a high-strength polyurethane elastomer insert[cite: 15]. Precision-engineered with lightweight aluminum alloy or heavy-duty S45C carbon steel hubs[cite: 15], this coupling combines small radial dimensions with a low moment of inertia, making it ideal for medium to high-speed motor applications. Its torsionally flexible structure effectively dampens mechanical shock loads while compensating for angular, radial, and axial shaft misalignments. Equipped with premium imported PU spider inserts, the DPG coupling operates completely lubrication-free and requires minimal long-term maintenance.

Key Advantages & Features

• Lightweight Design & Low Inertia: Compact radial construction with low moment of inertia, ensuring fast dynamic response and stable performance in high-speed rotation.
• Secure Clamping Hub Fixing: Integrated clamping screws deliver high gripping force across shaft connections, preventing slippage, keyway wear, and shaft deformation[cite: 15].
• Premium Bayer PU Elastomer Spider: Fitted with high-strength imported polyurethane (or Hytrel) spiders offering superior oil resistance, wear resistance, and high load-carrying capacity[cite: 15].
• Multi-Directional Misalignment Compensation: Flexibly absorbs dynamic angular offsets, parallel radial deviations, and axial play to protect connected drive equipment.
• Lubrication-Free & Low Maintenance: Completely dry-running design eliminates oil leaks, simplifies servicing, and provides extended operational lifespan under continuous duty.
• Durable Surface Finish Options: Available with surface anodizing for aluminum hubs or blackening treatment for steel hubs for enhanced corrosion protection[cite: 15].
