W 624 R-2RS1 Bearing Structural Features & Performance Benefits
Compact & Robust Flange Design: The integrated flange (15mm outer diameter) enables secure and simplified mounting, reducing installation space and costs while providing excellent axial location.
Superior Sealing & Contamination Protection: The 2RS1 double rubber seals effectively shield the bearing interior from dust, moisture, and other contaminants, significantly extending service life in harsh conditions.
High-Speed Capability: With a limiting speed of 32,000 rpm, this bearing is engineered for high-rotation applications. The stainless steel cage and optimized grease lubrication ensure stable operation at elevated speeds.
Maintenance-Free Operation: Pre-lubricated with high-quality grease and sealed for life, this bearing requires no relubrication, reducing maintenance needs and total cost of ownership.
Corrosion Resistance: All components (rings, balls, cage) are manufactured from stainless steel, providing excellent resistance to corrosion and enabling use in wet or chemically aggressive environments.
