Flexible Shaft Couplings

Couplings serve a crucial role in transmission system by connecting two shafts and facilitating the transmission of torque between them. These devices are essential in various applications where precise and reliable power transmission is required. When selecting couplings, it is crucial to consider factors such as Shaft Bore Diameter, Overall Length , Materials (e.g., Stainless Steel, Steel, Aluminum, Plastic and etc.), Features(e.g., Clean Environment, Heat Resistant , High Torque and so on). These considerations are vital for ensuring the production of high-quality products. We highly recommend reputable brands like MISUMI, ADVANCED, COUP-LINE, as well as cost-effective options from MISUMI ECONOMY.
Take advantage of the convenience of FREE SHIPPING and NO MINIMUM ORDER on couplings. If you have any doubts or require assistance in choosing the right product, our experts are readily available to provide.

Step Flex STF

MIKI PULLEY

Newly developed multi-layer rubber element achieves high attenuation and low recoil force. Couplings with high damping performance. For servo and stepper motors.
Integrated structure with no backlash that adopts HNBR for the power transmitting element. Damps vibration more quickly than a flexible coupling using metal for the elastic part.
This makes it possible to inhibit resonance, a phenomenon which tends to occur with stepper motors, etc. Helps avoid resonance over a wide range of operating speeds. Provides stable high speed control.
Furthermore, by using a layered rubber element sandwiched between HNBR with different levels of hardness, the shaft reaction force due to misalignment is reduced. The burden on the counter shaft and bearing can be reduced drastically.
