DBL41 Precision Double Diaphragm Couplings for High-Speed Motion Control

Our DBL41 series double diaphragm couplings are engineered for high-performance automation systems. By utilizing an expansion sleeve or taper sleeve connection, these couplings provide a secure, keyless interface that eliminates backlash and ensures maximum torque transmission efficiency.

Core Product Advantages

• High-Grade 45# Steel Construction: Manufactured from premium 45# round steel, offering high rigidity, high torque capacity, and low inertia for rapid response.

• 304 Stainless Steel Disc Pack: Features durable 304 stainless steel diaphragms (annular or square) that are rust-proof and capable of compensating for radial, angular, and axial misalignments.

• Zero Backlash & High Sensitivity: Designed with zero rotational clearance, providing identical clockwise and counter-clockwise rotation characteristics.

• H7 Precision Bore: Internal bores are controlled within H7 tolerance for high concentricity and precise fitment with motor shafts.

• Maintenance-Free & Quiet: Precision-engineered clearances ensure tight connections and noise-free operation even at speeds up to 15,000 r/m.

• Flexible Customization: We offer professional non-standard customization, including custom lengths, keyways, and diverse locking styles like taper sleeves or clamp types.
