Product Information
We manufacture and assemble cylindrical direct drive bearings, systems, and mechanical products with high accuracy and precision.
Spherical Rolling Joint
Up until now, the joints requiring multiple degrees of freedom that are indispensable for parallel mechanisms have achieved two or three degrees of freedom by combining rotational joints.
There are also sliding spherical bearings with multiple degrees of freedom, but they have had large friction resistance and internal clearances.
To solve these problems, HEPHAIST developed a spherical bearing with a rolling mechanism.
Ball spline unit
This is a linear motion mechanism that utilizes the rolling motion of a ball, enabling smoother movement within a limited range.
By mounting a rotary bearing, it can also support motion on the Θ-axis, and is used in a wide range of fields such as conveyor systems and robots.
High-accuracy positioning stages
HEPHAIST’s high-accuracy positioning stages have many unique features developed from original designs based on the machining technology that we have built up over many years for linear guide bearings and precision equipment parts.
