W 604-2RS1 Bearing Structural Features & Performance Benefits
Deep Groove Design: The optimized raceway geometry enables efficient handling of radial loads and moderate axial loads in both directions, providing versatile load capacity in a compact package.
Double Rubber Seals (2RS1): Both sides feature contact-type rubber seals that effectively prevent lubricant leakage and block the entry of contaminants, ensuring long-term reliability and maintenance-free operation.
Full Stainless Steel Construction: All components – rings, balls, and cage – are manufactured from stainless steel, offering excellent corrosion resistance and making the bearing suitable for harsh environments and applications requiring cleanliness.
Pre-lubricated Design: Factory-filled grease lubrication provides immediate operation readiness and consistent performance throughout the bearing's service life, supporting operation up to the limiting speed of 36,000 rpm.
