Four-Point Contact Ball Bearing Structure: This design allows the main ball to contact multiple support balls for load bearing, improving load-bearing capacity and stability, making it particularly suitable for high-impact and heavy-load environments. The four-point contact ball bearing mechanism also enables a compact design within limited space, making it suitable for installations with limited space.
"Ball Rotation" Support Function: The PSU20 Series' unique integrated ball rotation support structure allows the load to slide on the main ball while also enabling micro-rotation, enabling more flexible and precise movement and positioning of objects.
1. Strong Load-Bearing Capacity and Stable Four-Point Contact Bearing - The four-point contact ball structure distributes the load, extending service life and operational stability.
2. Multi-Directional Low-Friction Transmission - The "ball rotation" design ensures low friction and low thrust requirements during multi-directional transmission, making it suitable for high-speed/high-frequency operation.
3. Compact Support Assembly - Compared to traditional double-row structures, the four-point contact design occupies less axial space, making it more suitable for installation in confined spaces.
4. Reliable and durable, suitable for harsh environments - Available materials include stainless steel, ceramic, and high-temperature-resistant alloys to withstand harsh operating conditions such as high temperatures and dust.
5. Low maintenance and long life - Many utilize a pre-lubricated design and are equipped with protective features such as replaceable seals and drain holes to extend service life and ensure continuous operation.
PSU20 Series four-point contact ball swivel bearings are widely used in the following high-tech and precision equipment:
Industrial robotics and automation equipment: Robotic joints, rotary stages, automated workstations, etc. require precise and reliable rotational motion.
Medical equipment: CT machines, medical scanners, surgical robots, etc. demand high precision and trouble-free operation.
Precision measuring instruments: Rotating stages, optical instruments, etc. require extremely high positioning accuracy and stability.
