Material
The bearing’s core components are constructed from high-quality 52100 chromium steel, which offers exceptional hardness, wear resistance, and dimensional precision—key attributes for maintaining performance under continuous load. The double metal shields are made from galvanized steel, providing robust protection against particulate matter while withstanding moderate temperature fluctuations.
Characteristics
1. Superior dust shielding: The ZZ steel shields form a tight barrier against dust, lint, and small debris, making it ideal for use in clean but not fully sealed environments like electronics or precision tools.
2. High rotational efficiency: With minimal friction from the metal shields, the bearing supports smooth operation at elevated speeds, reducing energy loss and heat buildup.
3. Compact robustness: Its small form factor allows integration into space-constrained assemblies, while the high-strength steel construction ensures durability under radial loads.
4. Temperature tolerance: The metal shields and steel body enable stable performance in environments with temperatures up to 120°C, surpassing the limits of many rubber-sealed alternatives.
Applications
1. Small electronics: Such as cooling fans for microprocessors, hard drive spindles, and miniature motors in wearable devices, where dust protection and high speed are critical.
2. Precision robotics: Components like small actuators, gearbox shafts, and joint mechanisms in compact robotic systems, benefiting from its low friction and compact size.
3. Medical equipment: Including portable centrifuges, small pumps, and diagnostic device motors, where reliability and contamination resistance in dry settings are essential.
4. Hobby and craft machinery: Such as mini lathe spindles, 3D printer extruder motors, and high-speed model engines, leveraging its balance of performance and durability.
