Product Description
DFC Series High-Precision CNC Machine Flexible Plum Shaft Coupling
Â
Economy Clamping Type Plum Blossom Coupler for Servo Motors & CNC Automation (GR Interchangeable)
The DFC Series Flexible Plum Coupling is a high-precision, economical shaft coupling engineered for CNC machine tools, servo motors, stepper drives, and factory automation equipment[cite: 14]. Constructed with lightweight high-strength aluminum alloy or stainless steel hubs and a durable polyurethane elastic spider insert[cite: 14], this coupling features a secure clamping structure that ensures zero-backlash power transmission[cite: 14]. Designed as a cost-effective, direct replacement solution for standard GR series couplings, the DFC series excels in dampening operational vibrations, compensating for angular/radial misalignments, and maintaining high concentricity at continuous rotational speeds[cite: 14].
Key Advantages & Features
- High-Strength Lightweight Construction: Hubs are precision CNC-machined from anodized aluminum alloy or stainless steel, offering low rotational inertia, high strength, and excellent corrosion resistance[cite: 14].
- Zero-Backlash Clamping Hub Structure: Screw-clamping design distributes holding force evenly around the motor shaft, preventing shaft slipping, damage, or wear under frequent forward/reverse positioning[cite: 14].
- GR Series Direct Interchangeability: Dimensions match standard GR spider couplings, providing a seamless drop-in replacement for worn machine tool shaft couplers.
- Polyurethane Vibration-Dampening Insert: Elastic plum blossom spider cushion effectively absorbs shock loads, reduces acoustic noise, and extends machine spindle bearing life[cite: 14].
- Superior Angular & Parallel Misalignment Compensation: Protects delicate encoders, servo motors, and lead screws by compensating for minor shaft installation offsets[cite: 14].
- Anodized Surface Treatment: Hub surface undergoes optional anodization for enhanced wear resistance, neat aesthetics, and long-term durability[cite: 14].
