Spherical Surface Bearing SRJ

High rigidity and high-accuracy are realized by the zero-gap rolling guide.
[Features]
· The moving parts have a rolling bearing structure with a preload applied, so there is little frictional resistance and high-accuracy with zero clearance.
· Compared to a combination of roller bearings with 3 degrees of freedom, high rigidity and miniaturization have been achieved.
· Ideal for achieving high-accuracy, high rigidity and downsizing of parallel mechanism.
· Achieved using Hephaist's ultra-precision spherical inner surface machining technology.
