W 624-2RS1 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables efficient radial load distribution and accommodates moderate axial loads in both directions, providing versatile load capacity in compact dimensions.
Full Stainless Steel Construction: All components including rings, balls, and cage are manufactured from stainless steel, ensuring corrosion resistance and compatibility with washdown environments or applications requiring chemical resistance.
Double Rubber Seals (2RS1): Contact-type rubber seals on both sides effectively exclude contaminants while retaining lubricant, extending bearing service life and enabling maintenance-free operation in many applications.
Pre-lubricated Design: Factory-filled grease provides immediate operation readiness and supports the limiting speed of 32,000 rpm, making it suitable for high-speed miniature applications.
