Hollow Rotary Actuator Platform bearings

  • The hollow rotating platform is supported by a set of ZK hollow rotating platform bearings, which has a simplified structure and enhanced supporting performance. Because the rollers in the ZK hollow rotating platform bearings are staggered at 90 degrees, and the roller diameter is slightly larger than the raceway size between the inner and outer rings of the bearings, there is a preload between the inner and outer rings and rollers of the ZK hollow rotating platform bearings. The servo rotating platform turntable supported by the bearings can withstand various moments such as radial, axial, and overturning, and has high rotation positioning accuracy (up to 0.003mm), accurate positioning without gaps, and rigidity is more than 10 times that of traditional combined bearings, which greatly extends the service life of the rotating platform.

Hollow rotating platform bearings are not only new structural points in the development of industrial machinery, but also have many advantages such as high repeatability positioning system accuracy, high rotation accuracy, high rigidity, etc. The rolling elements of hollow rotating platform bearings generally use cylindrical rollers arranged crosswise on the inner ring raceway of the bearing. There is a preload between the inner and outer rings and the rollers, so that the bearings can withstand various torques such as axial, radial, and flipping. Its rigidity is higher than that of traditional bearings. ZK hollow rotating platform bearings are customized in design and manufacturing of structural dimensions, positioning holes, mounting holes and precision, which greatly facilitates customers' assembly and use. It has been widely used in hollow rotating platforms, DD motors, cam dividers, CNC machine tools, manipulator joints, machine tool fourth axis turntables and radar communication equipment.
MONTON Hollow Rotary Platform Bearing mainlydesign for applications requst precise rotational movement and load handling equipment. These bearingsown a hollow structure, allowing for the passage of cables, tubing, or other components cross through the bearing center, making them ideal for use in robotics, automation, and machine tool industries.
