A four-point contact ball swivel bearing is a special type of rolling bearing consisting of inner and outer rings, rolling elements (balls), and spacers. Unlike traditional single-row or double-row bearings, its unique raceway design allows each ball to form four contact points on the inner and outer ring raceways. This design greatly enhances the bearing's load-bearing capacity, enabling it to simultaneously withstand combined loads from multiple directions.
The PSI20 Series, with its superior performance, perfectly meets the needs of a wide range of industrial applications, including:
Construction Machinery: Equipment such as cranes, excavators, and aerial work platforms must withstand heavy loads and overturning moments. The PSI20 Series provides stable rotation and reliable support.
Automation Equipment: Industrial robots and rotary tables in automated production lines require extremely high precision and stability. The PSI20 Series ensures smooth operation.
Medical Equipment: CT scanners, operating tables, and other applications require high-precision rotating components. The PSI20 Series' low friction and high precision make it an ideal choice.
Wind Power Generation: The yaw systems of wind turbines must withstand significant wind loads. The PSI20 Series ensures safe and efficient operation.
1. Strong Load-Carrying Capacity
The unique four-point contact design enables the PSI20 Series slewing bearing to easily handle high axial and radial forces, as well as overturning moments. This versatility reduces the need for multiple bearings, simplifies design, and reduces costs.
2. High Precision and Stability
The PSI20 Series utilizes high-quality steel and precision manufacturing processes to ensure high rotational accuracy and low friction torque. It maintains excellent stability, whether operating at low speeds and heavy loads or at high speeds.
3. Compact and Lightweight Design
The PSI20 Series' compact design and low weight significantly save installation space and reduce overall equipment weight. This is crucial for applications where space is limited or lightweight is a requirement.
4. High Reliability and Long Life
We rigorously control the quality of every product, from raw material selection to final product inspection, ensuring exceptional reliability and exceptionally long service life even in harsh environments. This translates to less downtime and higher productivity.
Selecting the right PSI20 Series four-point contact ball swivel bearing is crucial to ensuring equipment performance and safety. When selecting a bearing, please provide the following information:
Working Load: The magnitude and direction of the axial load, radial load, and overturning moment.
Rotational Speed: The equipment's maximum speed and operating speed.
Installation Space: Inner diameter, outer diameter, and height restrictions.
Operating Environment: Special requirements such as temperature, humidity, and corrosive environments.
Our team of professional engineers can provide customized selection advice and technical support to ensure you receive the most suitable solution.
