Our radial contact thin section ball bearings not only achieve significant reductions in size and weight, but also provide unlimited possibilities for your innovative designs while maintaining high precision and stability.
With today's demanding demands for miniaturization, lightweighting, and high precision, traditional standard bearings often struggle to meet these demands. The PR Radial Contact Ball Bearing series of thin-walled ball bearings was developed to meet these demands. Their unique design and superior performance make them an ideal choice for precision machinery and equipment. Our thin-walled ball bearings not only significantly reduce size and weight, but also maintain high precision and stability, opening up endless possibilities for innovative designs.

Note
1: PRS can be customized.
2: All PRS products made of 52100/SUJ2/100Cr6/100CrMn6. If you have special requirements, plesse specify when ordering.
1. Space-Saving and Lightweight Design
The most significant feature of thin-wall ball bearings is their extremely small cross-sectional area. Compared to standard bearings, their cross-sectional dimensions are compressed to the extreme, achieving an ultra-thin design. This saves valuable installation space in your equipment while significantly reducing overall weight. This lightweight design offers significant advantages in aerospace, medical equipment, robotics, and semiconductor manufacturing.
2. High Precision and High Performance
Despite their reduced wall thickness, our PR thin-wall ball bearings maintain exceptional manufacturing precision. We utilize advanced production processes and high-quality raw materials to ensure that each bearing has extremely close tolerances and excellent running performance. This ensures smooth, low-noise, and low-vibration operation at high speeds, extending equipment life and improving efficiency.
3. Diverse Structures and Applications
The PR Radial Contact Ball Bearing series of thin-wall ball bearings offers a variety of structure types to meet the specific needs of different users:
Radial Contact Ball Bearing: Primarily bears radial loads and is ideal for high-speed rotation and applications requiring high rigidity.
Angular Contact Ball Bearing: Can simultaneously support radial and axial loads, making it particularly suitable for precision equipment requiring precise control of axial displacement.
Four-Point Contact Ball Bearing: Can simultaneously support axial loads in both directions and can replace two angular contact bearings in a single bearing, further simplifying design and saving space.
4. Reduced Friction and Energy Consumption
The optimized internal structure and precision manufacturing process effectively reduce frictional torque within the bearing. This not only ensures smoother equipment operation but also significantly reduces energy consumption. The low friction characteristics of PR thin-walled ball bearings are of great value for battery-powered equipment or equipment with strict energy requirements, such as drones and medical diagnostic equipment.
We understand that selecting the right bearing is critical to ensuring equipment performance and reliability. PR Radial Contact Ball Bearing is committed to providing high-performance thin-walled ball bearing solutions to customers worldwide. Our products undergo rigorous quality control and testing, meet international standards, and are widely used in:
Robotics: Used in joints, servo motors, and precision actuators.
Medical devices: such as CT scanners, surgical robots, and analytical instruments.
Aerospace: Satellite antennas, optical equipment, and navigation systems.
Semiconductor equipment: Wafer processing equipment, photolithography machines, etc.
Precision instruments: Optical encoders, CNC machine tools, etc.
If you are looking for precision bearing solutions that improve device performance, achieve lightweighting, and miniaturization, PR Radial Contact Ball Bearing's thin-section ball bearings are your best choice. We look forward to collaborating with you to explore the future of innovation.
