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.

Optimal design thanks to 3D-CAD and FEM analysis

The latest CAE system was used from the initial stages of design. These models were designed using 3D-CAD. Shape and hardness was designed using the support of the latest finite element method (FEM) analysis software for optimal designs.

High transmission torque achieved and mounting error reaction force reduced by optimal design of element shape

They achieve more than double the transmission torque of older jaw couplings for the same outer diameter thanks to improved torque transmission component shapes and rigorous selection of materials.Couplings that have no backlash (ALS Y and R type) and are gentle on the partner shaft have been achieved by installing an undercut on the inner diameter side and reducing the mounting error reaction force.

Can be freely combined

Select from among three types of hubs: pilot-bore types that can be freely drilled with bores, key/set screw types, and clamp types.Key/set screw types and clamp types can also be combined.
