Claw couplings / mounting selectable / claw disc: PU, Shore A97 / body: aluminium / ALS-R / MIKI PULLEY

MIKI PULLEY

Element hardness 97JIS A used, designed to use preliminary compression with no backlash. Supports a wide range of applications, from simple servo to general purpose motor with high torque.

[Features]
· Polyurethane elastomer used for element. So, the transmission torque is more than twice that of conventional jaw coupling.
· Design to distribute pre-compression, and so can be used with no backlash. (ALS-Y/R type)
· Power transmission through polyurethane elastomer with rubber elastic force. It has excellent vibration and impact absorption.

Flexible Shaft Coupling Accessories - EK Series Elastomer Inserts

R+W

The equalizing element of the EK coupling is the elastomer insert. It transmits torque without backlash or vibration. The elastomer insert defines the characteristics of the entire drive system.

Backlash is eliminated by the press fit of the elastomer into the hubs. Through variation of the Shore hardness of the elastomer insert, the coupling system can be optimized for the ideal torsional characteristics.
