Material
This bearing is primarily constructed from high-grade carbon chromium steel (52100). This material offers superior toughness, corrosion resistance, and dimensional stability, enabling the bearing to maintain consistent performance across different temperature ranges and operational conditions.
Characteristics
1. Enhanced sealing: Equipped with double rubber seals (2RS) on both sides, it provides excellent protection against moisture, dust, and particulate matter, making it suitable for use in semi-harsh environments where contamination risks exist.
2. Low friction operation: The precision-ground raceways and optimized ball complement minimize rotational friction, contributing to energy efficiency and reduced heat generation.
3. Compact design: Its small outer diameter and thin section allow for easy integration into space-constrained equipment without compromising load-bearing capacity.
4. Maintenance-friendly: The rubber seals help retain lubricant effectively, reducing the need for frequent re-lubrication and extending service intervals.
Applications
1. Small household appliances: Such as electric mixers, coffee grinders, and portable blenders, where reliable sealing and compact size are essential.
2. Precision tools: Including handheld drills, mini lathes, and hobbyist 3D printers, benefiting from its low friction and space-saving attributes.
3. Medical devices: Like portable infusion pumps and small diagnostic equipment, where cleanliness and consistent performance are critical.
4. Automotive accessories: For components such as window regulators, small fans, and seat adjustment mechanisms, leveraging its durability and sealing capabilities.
