HEPHAIST Needle Roller Bearings
Aligning Spherical Bearings
By combining rotary joints with 2 to 3 degrees of freedom, joints with multiple degrees of freedom that are essential for parallel mechanisms are obtained. However, these joints have the advantage of being structurally complex and large. There are also sliding spherical bearings with multiple degrees of freedom, but they have larger friction resistance and internal clearance. To solve these problems, Heheist developed a roller spherical bearing.
