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 R 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 Y 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.

ALS B TYPE
