The S4200 series bearings are double-row deep groove ball bearings, designed similarly to two paired single-row deep groove ball bearings. These bearings offer the following features:
Double-row design: Comprising two parallel deep groove ball bearings, they can simultaneously withstand radial loads and bidirectional axial loads.
High-speed performance: Engineered for high-speed operation with low noise and excellent operational stability.
Material and corrosion resistance: Manufactured from stainless steel, providing superior corrosion resistance.
Medical devices: Ideal for equipment requiring high levels of hygiene and corrosion resistance.
Aerospace: Capable of enduring heavy loads and harsh environments.
Robotics: Fits well in mechanical arms and joints demanding high precision and reliability.
Precision instruments: Ensures smooth and reliable operation during high-speed processes.
