Versatile Shaft-to-Shaft Alignment: Industrial L-Type Flexible Jaw Coupling Series

The L-Type Flexible Jaw Type Coupling Series delivers an exceptional, multi-material power transmission solution engineered to resolve shaft-to-shaft misalignments, absorb sudden torsional shocks, and eliminate high-frequency mechanical vibrations. In complex drivetrain setups, rigid couplings can pass structural stress directly into motor bearings, accelerating wear and causing early failure. This L-type elastic coupling prevents this issue by pairing two precision-formed interlocking jaw hubs with a high-quality central rubber spider insert (NBR black pad). This fail-safe design cushions continuous operation, cuts equipment weight, and eliminates lubrication requirements entirely—making it ideal for light automation like wave soldering machines, as well as rugged conveyor systems, processing pumps, and industrial electric motors.

As shown in the technical profile in image_f2a683.png, this robust mechanical line features high adaptability. It spans from small-to-medium Sintered Iron (L035 to L190) powder metallurgy hubs up to heavy-duty Cast Iron (L225 to L276) variants. Standard configurations confidently support a 30 mm (1.18 in) bore diameter, a high rated torque capacity up to 300 N·m (221.27 lb.ft) , and a balanced maximum operating velocity of 2000 RPM.
