Coupling for small engine machinery MONOLASTIC

Coupling for small engine machinery MONOLASTIC

Motor dampers with good mounting compatibility in a one-piece design.

The MONOLASTI C series, like the BoWex series, has numerous achievements in both domestic and international markets for motor-driven machinery. It features a low torsional rigidity specification using natural rubber, which provides the ability to absorb vibrations and impacts, as well as the capability to shift the resonance rotational speed of the drive system to a position lower than the operating rotational range. (Detailed selection will be verified through our torsional vibration calculations.) The flange that attaches to the engine flywheel, the hub for inserting the pump shaft, and the rubber component responsible for power transmission are all integrated, making installation easy, which has been well received by our customers.

Hysteresis Magnetic Coupling MINEX-H

Hysteresis Magnetic Coupling MINEX-H

A magnetic coupling that functions as a wear-free torque limiter!

Features: • Transmits torque non-contact through magnetic force • Can be used as a wear-free torque limiter • Maintenance-free In the event of overload, it contributes to creating a safe operating environment by allowing the power to run idle and cutting off the power. After slipping, if it returns below the set torque, it will synchronize and rotate again (this is not a return to the origin). Since power transmission is achieved through the synchronization of permanent magnets, there are no sliding surfaces, eliminating concerns about dust (the following applications are anticipated). Consider it a wear-free torque limiter. 【Applications】 Filling machines for food and pharmaceuticals, film winding machines, material handling equipment, hoists.
