Ring jaw couplings / hub clamp / claw disc: laminated rubber, 3-star / Body: aluminium / STF / MIKI PULLEY

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.

Servo couplings / grub screw clamping, hub clamping / 1 disc: steel, PA, CFK / body: aluminium / MS, MSC / ADVANCED

ADVANCED

· Universal type resistant to small misalignment
· Multiple disc materials support a wide range of uses
· Polyimide - Demonstrates outstanding flexibility and low reaction force even if misaligned, and causes no phase or torque fluctuation
· Well-balanced versatile type featuring excellent carbon FRP-flexibility, transmission torque, and torsional rigidity
· Stainless steel flat spring (SUS) - Inferior flexibility, but high transmission torque and torsional rigidity, so it is ideal for highly responsive servo systems
