Core features and advantages of PU Series Four-point Contact Ball Slewing Bearings

The PU Series four-point contact ball slewing bearing utilizes a unique four-point contact ball structure, allowing a single ball race to simultaneously withstand axial, radial, and overturning moments. This design not only significantly increases the bearing's load capacity but also provides higher rigidity for a given size, effectively reducing deformation during operation and ensuring high-precision motion.

Lightweight Design, Space Savings: The PU Series features small dimensions and low weight. Compared to traditional double-row ball bearings, its more compact structure significantly reduces installation space and weight, which is particularly important in space- and weight-critical applications such as robotic joints and precision turntables.

Excellent Motion Precision and Rigidity: The meticulously optimized internal structure and tight manufacturing tolerances ensure the PU Series maintains extremely high rotational accuracy under various operating conditions. This exceptional rigidity ensures smooth and precise operation even under load, significantly enhancing overall equipment performance.

High Load Capacity: Despite its compact size, the PU Series four-point contact ball slewing bearing offers significant load-bearing capacity. A single bearing can simultaneously support complex loads from multiple directions, making it an excellent choice for a variety of lightweight slewing bearing applications.

High Reliability and Long Life: High-quality materials and precision machining ensure long product life and high reliability. Designed from the outset for demanding operating environments, the PU Series offers stable operation and reduced maintenance.

Various Sizes and Customization Options: We offer the PU Series in a variety of standard sizes and can also customize it to your specific needs, ensuring a perfect fit for your equipment design.
