635-2RS Double Rubber Seal Bearings 5x19x6mm,ABEC-5 Z3V3 High Speed Sealed

Key Product Features

• Superior Sealing Performance: Equipped with double-sided rubber contact seals, the 635-2RS effectively prevents the ingress of dust, moisture, and contaminants . This sealing design significantly extends operational lifespan by reducing lubricant loss and internal component wear .
• High-Speed Capability: Optimized with super-finished raceways and controlled geometries, this bearing supports exceptional high-speed operation. It achieves a limiting speed of up to 38,000 rpm under grease lubrication and 45,000 rpm with oil lubrication, making it suitable for high-rotation applications .
• Versatile Load-Bearing Capacity: As a single-row deep groove ball bearing, it accommodates both radial and axial loads in both directions. With a dynamic load rating of 2300 N and a static load rating of 890 N, it performs reliably in light to moderate duty scenarios .
• Durable Material Construction: The standard version is crafted from high-quality chrome steel for inner/outer rings and balls, paired with a pressed steel cage for structural stability. For specialized demands, optional full ceramic versions are available, offering superior heat resistance, corrosion resistance, non-magnetic properties, and electrical insulation .
• Low Maintenance & Easy Installation: Factory pre-lubrication eliminates the need for additional lubrication before initial use. Its cylindrical bore design and compact size (net weight only 0.0081 kg) enable easy mounting in space-constrained equipment, requiring minimal maintenance compared to other bearing types .
