Product Information

MIKI PULLEY STARFLEX

Double the previous transmission torque (compared to our previous product), a simple jaw coupling

The simple construction of these couplings sandwiches a buffer piece called an element (made of polyurethane elastomer) between two hubs. Elements of two different hardnesses are available so you can select the appropriate one for your torque transmission responsiveness and amount of misalignment. The polyurethane elastomer used in the element enables double the torque transmission of our previous jaw coupling (Miki comparison), and since the design pre-compresses the element, it can also be used without backlash. Aluminum alloy is used as the hub material. The hub may be coupled to the shaft either by key or by clamp.

ALS R Type

Uses an element (polyurethane elastomer) with a hardness of 97 JIS A and a tight-fit construction designed for a pre-compressed shape, so the coupling can be used without backlash.It can be used at high torque and a wide range of motors, from simple servos to general-purpose motors.

ALS Y Type

Uses an element (polyurethane elastomer) with a hardness of 90 JIS A and a tight-fit construction designed for a pre-compressed shape, so the coupling can be used without backlash.Elements are less hard than the ALS-R type, so shaft reaction force can be kept down.

ALS B Type

Large misalignments can be absorbed at high transmission torques by using an element (polyurethane elastomer) with a hardness of 97 JIS A, a shape that has a loose-fit construction, and giving the torque transmission surface of the element a crowning shape.
