Material
The bearing’s inner and outer rings, along with the rolling elements, are made from high-purity 52100 chromium steel, which offers exceptional hardness and wear resistance to withstand the stresses of micro-scale operation. The 2RS seals are crafted from nitrile rubber (NBR), providing excellent flexibility, oil resistance, and a tight seal to prevent lubricant leakage and contamination ingress.
Characteristics
1. Ultra-compact design: With an extremely small outer diameter and width, it fits seamlessly into miniaturized devices such as micro-motors and tiny actuators.
2. Effective sealing: The rubber seals create a barrier against water vapor, dust, and small debris, making it suitable for use in semi-humid or dusty micro-environments.
3. Low friction and quiet operation: Precision machining of raceways and the damping effect of rubber seals minimize noise and friction, essential for sensitive equipment.
4. Pre-lubricated for longevity: Factory-filled with high-performance micro-grease, the seals retain lubrication effectively, reducing maintenance needs in hard-to-access assemblies.
Applications
1. Micro-electronics: Such as small vibration motors in smartwatches, miniature cooling fans for microprocessors, and sensor rotation mechanisms.
2. Precision medical devices: Including 微型 pumps for insulin delivery systems, tiny rotating components in endoscopes, and portable diagnostic tools.
3. Hobbyist and wearable tech: Like small drone motors, miniature robotics kits, and components in fitness trackers with rotating parts.
4. Office and consumer mini-tools: Such as tiny printers in receipt machines, micro-scanners, and compact camera lens adjustment mechanisms.
