DFCG Stainless Steel High-Precision Flexible Plum Jaw Coupling (Clamp Style)

Zero-Backlash SUS304 Motor Shaft Coupler with Polyurethane / Hytrel Spider Insert

The DFCG Series Stainless Steel Flexible Plum Jaw Coupling is a high-precision, zero-backlash shaft coupling engineered for demanding motion control systems, servo motor drives, and corrosive working environments. Constructed with high-grade SUS304 stainless steel hubs and a premium polyurethane (PU) or Hytrel elastomeric spider insert, this coupling delivers exceptional torsional stiffness, superior vibration damping, and compensation for radial, angular, and axial shaft misalignments. Featuring a clamp-screw fastening mechanism and detachable 3-piece design, the DFCG series ensures secure shaft clamping and effortless installation without damaging precision drive shafts.

Key Advantages & Features

• SUS304 Stainless Steel Hubs: Manufactured from premium SUS304 stainless steel, offering outstanding corrosion resistance, rust prevention, and chemical stability for cleanroom and food-grade environments.
• Zero Rotational Backlash: High-precision jaw geometry ensures zero backlash execution, making it suitable for high-frequency forward and reverse rotation drives.
• High-Damping Polyurethane / Hytrel Spider: High-hardness (98 Shore A) elastic spider pad absorbs operational shock loads, insulates electrical current, and resists oil and mechanical wear.
• Multi-Directional Misalignment Compensation: Efficiently absorbs operational vibration while compensating for parallel, angular, and axial shaft offsets.
• Non-Destructive Clamp Screw Locking: Clamping hub configuration ensures equalized radial clamping force, high concentricity, and simple maintenance.
• Detachable & Maintenance-Free Structure: Split construction allows for fast assembly, easy inspection, and long service life without lubrication.
