Sill Bearing
Explore our high-performance 6004zz series and specialized industrial bearings.
The 6004zz deep groove ball bearing (20mm x 42mm x 12mm) remains one of the most versatile and high-demand components in the global industrial market. As the backbone of rotary motion, these bearings are shielded on both sides (ZZ) to retain lubrication and prevent dust ingress, making them indispensable for high-speed applications.
From the bustling manufacturing hubs of Southeast Asia to the automated factories of North America, the 6004zz bearing facilitates silent operation and durability. As the "Bread and Butter" of the bearing industry, the global market for deep groove ball bearings is projected to reach billions of dollars by 2030, driven by the surge in Electric Vehicle (EV) production and advanced robotics.
The bearing industry is undergoing a digital and material revolution. Modern China 6004zz bearing manufacturers are no longer just making steel rings; they are engineering "Smart Components." Key trends include:
The 6004zz is the preferred choice for small to medium electric motors and ventilation systems where low noise and vibration are critical for consumer satisfaction.
Used extensively in alternators and gearbox assemblies, our bearings ensure that vehicles remain on the road longer with minimal maintenance costs.
From high-speed drills to industrial saws, the 6004zz provides the robustness required to handle axial and radial loads simultaneously.
Located in the heart of China's industrial power, we offer more than just products; we offer reliability.
SILL BEARING FACTORY is strategically located in the Hangzhou Bay New Zone, a premier industrial hub. This location offers unparalleled logistical advantages:
International buyers prioritize consistency. Our factory implements 100% automated inspection processes to ensure every 6004zz bearing meets P6 or P5 precision standards.
By leveraging China's complete industrial supply chain, we offer competitive pricing without compromising the metallurgical integrity of our bearings.
With our advanced inventory management and proximity to major ports, we mitigate global supply chain disruptions, ensuring on-time delivery for OEM orders.
The technical designation 6004zz deciphers into specific engineering advantages. The '6' denotes the single-row deep groove ball bearing type, '00' indicates the extra-light series, and '04' translates to a 20mm bore diameter (4 x 5mm). The suffix 'ZZ' signifies the presence of double-sided metallic shields. Unlike open bearings or '2RS' (rubber sealed) variants, 'ZZ' bearings provide a low-friction metallic barrier that excels in higher temperature environments where rubber might degrade.
SILL BEARING FACTORY, is located in the beautiful and affluent place named Hangzhou Bay New Zone, which is not only close to the two biggest ports of China—Shanghai port and Ningbo Port, but also adjacent to Hangzhou—Ningbo Expressway, 329 State Line and Hangzhou- Ningbo Railway Line. Besides, it owns the advantage of transportation, as it only takes about 90 minutes to go to Hangzhou Xiaoshan Airport or Ningbo Lishe Airport.
