Widely used in shaft drive systems for various mechanical devices, such as water pumps (especially high-power and chemical pumps), fans, compressors, hydraulic machinery, petroleum equipment, printing machinery, textile machinery, chemical machinery, mining equipment, metallurgical equipment, and aviation (helicopters, etc.).
High-speed power transmission systems for aircraft and naval vessels, steam turbines, reciprocating engine power transmission systems, tracked vehicles, and high-speed, high-power mechanical transmission systems for power generation units, after dynamic balancing, are now commonly applied in high-speed shafting systems.
