W 623 R-2RS1 Bearing Structural Features & Performance Benefits
Deep Groove Design: The optimized raceway geometry enables the bearing to handle both radial loads and moderate axial loads in both directions, making it versatile for various mounting configurations.
Stainless Steel Construction: All components including rings, balls, and cage are manufactured from stainless steel, providing excellent corrosion resistance and suitability for applications requiring frequent washdown or exposure to moisture.
Double Sealing System: The 2RS1 contact seals effectively prevent the ingress of contaminants while retaining the factory-applied grease, ensuring long service life without maintenance requirements.
Flange Design: The integrated flange (11.5mm outer diameter) simplifies installation and provides accurate axial positioning, reducing assembly time and costs in precision mechanisms.
Precision Manufacturing: Manufactured to P0 tolerance class with CN radial clearance, the bearing delivers consistent performance and smooth operation across its operating temperature range of -30°C to 120°C.
