The ML Series jaw flex coupling is engineered for high-torque power transmission in demanding industrial environments. Constructed from durable 45# steel with surface oxidation treatment, this flexible coupling delivers exceptional strength and corrosion resistance. Its advanced jaw and spider design effectively absorbs vibrations, compensates for radial and angular misalignments, and dampens torsional vibrations, ensuring smooth operation and extended equipment life.

Available in standard sizes from ML1 to ML13 (equivalent to S50-S230), this coupling features axial plug-in installation for easy assembly and maintenance-free operation. With a rated torque range of 25-12,500 N.m and maximum torque capacity up to 19,000 N.m, it handles rigorous applications in hydraulic pumps, compressors, and heavy machinery. The coupling operates efficiently in temperatures from -30°C to +80°C and offers multiple spider options with different hardness levels (≥98 Shore A) and petal configurations (4, 6, 8, or 10 petals) to suit specific application requirements.

Description
The ML Series flexible coupling represents the pinnacle of jaw coupling technology, specifically designed for heavy-duty industrial applications. This coupling excels in transmitting torque while effectively damping torsional vibrations and accommodating shaft misalignments. The precision-engineered steel hubs combined with replaceable elastomeric spiders create a reliable connection that protects both driving and driven equipment from damage.

Particularly suitable for hydraulic systems, pump applications, and high-torque machinery, the ML coupling’s compact design makes it ideal for applications with limited space. The availability of spiders in different materials and hardness levels allows for customization based on specific operational needs, whether for high-temperature resistance, chemical compatibility, or specific damping characteristics. With standard sizing that ensures interchangeability and multiple fixation methods, this coupling offers both performance versatility and installation flexibility.
