Material
It is made from high-grade 52100 bearing steel, which undergoes strict heat treatment. This material ensures excellent hardness, wear resistance, and dimensional stability, allowing the bearing to perform well in long-term operations.
Features
• Double rubber seals ("2RS"): These seals offer superior protection against water, oil, and fine contaminants, maintaining internal lubrication more effectively than metal shields, especially in humid or dusty environments.
• Low friction: The precision-machined raceways and rolling elements minimize friction, enabling smooth and quiet rotation.
• Compact structure: Its small size makes it suitable for applications with limited installation space.
• Good load capacity: Despite its compactness, it can bear moderate radial loads stably.
Applications
• Garden equipment: Used in small lawnmower motors and water sprinkler mechanisms.
• Household appliances: Applied in humid environments like washing machine pump components and dishwasher small motors.
• Personal care devices: Integrated into electric toothbrushes and hair clippers that may come into contact with moisture.
• Small industrial pumps: Utilized in miniature liquid transfer pumps where sealing performance is crucial.
