6201-ZZ Deep Groove Ball Bearing GCr15 Steel P6 Z3V3 Low Noise Dustproof Bearing for Vacuum Cleaners, Sewing Machines
The 6201-ZZ is a single-row deep groove ball bearing with double-sided metal shields, engineered for high-speed, low-noise and dust-proof working conditions. It is manufactured from high-purity GCr15 bearing steel and hardened through precise quenching and tempering, giving it high hardness, strong wear resistance and stable fatigue performance. The finely polished raceways and steel balls deliver smooth, low-friction rotation, while the ZZ metal shields keep dust, particles and debris out and hold the factory grease in place.
Compact in structure and reliable in performance, the 6201-ZZ is a core matching component for small and medium motor-driven equipment, and is widely chosen for vacuum cleaner motors and sewing machines where quiet, high-speed and dust-resistant running is essential.
2. Core Product Functions
- Dust-proof & anti-leakage: Double-sided ZZ metal shields isolate external dust and impurities and lock the lubricating grease firmly, avoiding grease drying and leakage and greatly extending service life.
- Low noise & smooth operation: High-precision grinding of raceways and balls reduces running friction and vibration for quiet, stable operation that suits noise-sensitive equipment.
- High-speed capability: The non-contact metal shield design keeps friction and heat low, supporting continuous high-speed running with low power loss.
- Composite load bearing: Handles both radial load and moderate bidirectional axial load with uniform stress and strong operational stability.
- Easy installation & low maintenance: Standard 12x32x10mm universal size with high interchangeability, simple assembly and no frequent maintenance.
