Material
Constructed from high-quality 52100 chromium steel, this bearing boasts excellent mechanical properties including high hardness, strong wear resistance, and good dimensional stability. The rubber seals are made from nitrile rubber (NBR), known for its compatibility with various lubricants and resistance to oils, ensuring long-term sealing effectiveness.
Characteristics
1. Superior sealing: The 2RS rubber seals form a tight barrier against water, oil, and fine dust, making it suitable for damp or slightly contaminated environments such as bathroom appliances or outdoor small machinery.
2. Low noise operation: The rubber seals and precision-machined raceways reduce vibration and friction-induced noise, ideal for equipment requiring quiet performance.
3. Pre-lubricated design: Factory-filled with high-performance grease, the bearing arrives ready for use with minimal need for initial maintenance, ensuring consistent operation from the start.
4. Moderate speed compatibility: While offering better sealing than metal-shielded variants, it operates efficiently at moderate speeds, striking a balance between protection and rotational dynamics.
Applications
1. Household water-related appliances: Such as small water pumps, humidifiers, and electric toothbrushes, where resistance to water ingress is critical.
2. Personal care devices: Including hair clippers, electric shavers, and massagers, benefiting from low noise and dust protection.
3. Outdoor small machinery: Like garden mini-sprinklers or portable generators, where exposure to moisture and debris is common.
4. Medical tools: Such as handheld diagnostic devices and small pumps, requiring reliable sealing to maintain sterility and performance.
