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.
