Features

• Universal joint plus allowable end play function.
• A simple three-element structure consisting of an outer hub, an inner hub (aluminum), and a sphere.
• Uses strong viscosity special grease.
• Compact and powerful, ideal for miniaturizing mechanisms.
• Optionally, bellows can be attached to NBS50 and above.
• [Ball Coupling]
• Ball couplings are rotation-transmitting elements that combine the functions of universal joints and splines.
• The ball coupling consisting of three elements, an inner hub, an outer hub and a ball, has been patented for its functional structure.
• There are no size restrictions, so there are many possibilities from micro to large couplings.
• Compared to the size of the outer shape, the transmission torque, especially the damage torque, is large, so the device can be miniaturized.
• Since there are no basic restrictions on the material of the hub and ball, it can be used in water, oil, high temperature and low temperature vacuum.
• Couplings of declination angle and eccentricity (spline) amount can be designed to suit the required use in actual production.
• We can expect future developments in such fields as micro-robots, automatic machines, packaging machines, and large industrial machines.
• High speed and high rigidity servo support can also be considered.
