68-5639-49 ball coupling NBS50-18-22

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.
