The 6004-ZZ is a versatile single-row deep groove ball bearing with double-sided metal shields, specially designed for medium-speed, low-noise and dust-proof working conditions. Manufactured from high-purity GCr15 bearing steel and processed through precise quenching and tempering heat treatment, this bearing delivers high hardness, excellent wear resistance and stable fatigue resistance. With a compact 20x42x12mm structure, standardized dimensional accuracy and finely ground raceways, it achieves ultra-smooth rotation and minimal friction. The ZZ double metal sealing structure effectively blocks dust, particles and debris from entering the bearing interior, preventing grease leakage and early wear. Reliable and cost-effective, it is a core matching component for food processing machinery, household appliances, pumps and various small and medium-sized industrial equipment.
2. Core Product Functions
Dust-proof & Anti-leakage Performance: Equipped with double-sided ZZ metal sealed shields, the bearing isolates external dust and impurities, and locks internal lubricating grease firmly, avoiding grease drying and leakage, greatly extending service life.
Low Noise & Smooth Operation: Adopting high-precision grinding process for raceways and steel balls, it reduces running friction and vibration, realizing quiet and stable operation, perfectly adapting to noise-sensitive equipment.
Composite Load Bearing: It can bear both radial load and moderate bidirectional axial load, with uniform stress and strong operational stability, meeting daily industrial load demands.
High Speed & Durability: Premium material and standardized heat treatment ensure high structural rigidity and fatigue resistance, supporting long-term continuous medium-speed operation without easy failure.
Easy Installation & Low Maintenance: Standard universal size with high interchangeability, simple assembly and disassembly, no frequent maintenance required, reducing equipment operating costs.
