Product Description
Our ML Series mechanical coupling represents the pinnacle of flexible shaft coupling technology, engineered for superior performance in demanding industrial environments. Constructed from high-grade 45# steel with blackening surface treatment, this robust coupling features an advanced jaw and spider design with a high-strength polyurethane elastomer that delivers exceptional vibration damping, electrical insulation, and misalignment compensation capabilities.
These flexible shaft couplings excel in transmitting torque while accommodating significant axial, radial, and angular deviations, protecting your valuable equipment from premature wear and damage. With a comprehensive size range from ML1 to ML14 and weights spanning 0.657kg to 127.59kg, our mechanical couplings offer versatile solutions for applications across manufacturing plants, construction machinery, and material handling systems. The polyurethane spider element resists oil, wear, and degradation, ensuring long service life without requiring lubrication. This maintenance-free design, combined with compact dimensions and low inertia, makes our flexible shaft couplings ideal for medium to high-speed applications where reliability and efficiency are paramount.
Features
Premium 45# steel construction with protective blackening treatment
High-strength polyurethane spider for superior elasticity and durability
Compact, lightweight design with minimal rotational inertia
Excellent electrical insulation properties
Maintenance-free operation with no lubrication requirements
Customizable sizes and specifications for OEM applications
Simple installation and reliable long-term performance
Description
The ML Series flexible shaft coupling is a mechanical power transmission component designed to connect two shafts while effectively compensating for misalignment and absorbing shock loads. This coupling utilizes a unique jaw and spider configuration where the polyurethane elastomer acts as a flexible element between precision-machined steel hubs. The result is smooth power transmission with exceptional damping characteristics that protect both driving and driven equipment.
Ideal for a wide range of industrial machinery including pumps, compressors, conveyors, and processing equipment, these mechanical couplings offer reliable performance in challenging operating conditions. The polyurethane spider material provides excellent resistance to oils, abrasion, and environmental factors, ensuring consistent operation without degradation. Available in standard sizes with customization options, our flexible shaft couplings deliver the perfect balance of strength, flexibility, and durability for your specific application requirements.
