1. Excellent Load Capacity and Precision
The PLI20 slewing bearing utilizes a four-point contact ball design, allowing a single bearing to simultaneously support axial, radial, and tilting moments. This design significantly simplifies the mechanical structure and reduces overall weight, while ensuring high load capacity and rigidity. This is crucial for applications requiring precise positioning and stable operation, such as industrial robots, automated equipment, and medical devices.
2. Compact and Lightweight Design, Optimizing Equipment Space
A key advantage of the PLI20 series lies in its thin-walled structure and compact design. Compared to traditional bearings, it significantly reduces equipment size and weight, providing greater design flexibility. Whether in space-constrained automated production lines or lightweight wind turbines, the PLI20 is a perfect fit, helping you improve overall equipment performance and energy efficiency.
3. Easy Installation and Maintenance, Lowering Operating Costs
The PLI20 series features a preloaded design and is precisely adjusted at the factory, simplifying installation. Furthermore, it is fully sealed to effectively prevent the ingress of dust and contaminants, extending service life and reducing maintenance frequency and costs.
The PLI20 series is widely used in:
Industrial robots
Automation equipment
Medical equipment
Packaging machinery
Wind turbines
If you are looking for a high-performance, high-precision, and lightweight slewing bearing, the PLI20 series is your best choice. It will not only significantly improve your equipment performance, but also provide greater economic benefits through its compact design and low maintenance costs.
