Spherical Rolling Joint SRJ series

Joints with multiple degrees of freedom essential to parallel mechanism have conventionally obtained 2~3 degrees of freedom by combining rotational joints.
However, these joints have been characterized by upsizing due to complex structure.
Sliding spherical joints with multiple degrees of freedom have also been available, however, they have had large frictional resistance and inner clearance.
In order to resolve these problems, HEPHAIST SEIKO has developed rolling Spherical Rolling Joint.
