Sill Bearing
Sill Bearing
In the landscape of global industrial manufacturing, the 6208 ZZ Deep Groove Ball Bearing represents more than just a mechanical component; it is the backbone of rotational efficiency across diverse sectors. From the high-speed rotors of electric motors to the rugged axles of agricultural machinery, the 6208 ZZ—characterized by its 40mm bore, 80mm outer diameter, and dual metal shields—is a global standard. As a leading China 6208 ZZ Bearing Manufacturer, SILL BEARING FACTORY integrates decades of metallurgical expertise with state-of-the-art automated production to deliver components that meet the rigorous demands of the 21st-century economy.
Located in the Hangzhou Bay New Zone, we are strategically positioned near Shanghai and Ningbo ports. This proximity reduces transit times and logistical costs for our global partners.
We utilize superior GCr15 bearing steel to ensure maximum hardness and wear resistance. Our focus ranges from ￠4mm to ￠120mm deep groove ball bearings.
With our new facility, Anhui TOPB IMP.&EXP. Co., Ltd., under construction, our annual production capacity is set to surge by $20 million, meeting rising global demand.
Modern Chinese bearing factories have moved beyond manual labor. Our lines feature AI-driven automated inspection systems that detect micro-fractures invisible to the human eye, ensuring the "100% acceptance rate" we promise.
The rise of Electric Vehicles (EVs) requires bearings with lower friction coefficients. We are currently innovating 6208 ZZ variants with low-torque grease and optimized internal geometries for EV drivetrains.
Being 90 minutes from Ningbo Lishe Airport and adjacent to major expressways ensures that even in volatile global markets, our supply chain remains robust and responsive.
Our 6208 ZZ bearings are manufactured to ISO/DIN standards, ensuring seamless replacement for SKF, FAG, or NSK equivalents. We provide full documentation for RoHS and REACH compliance, essential for European and North American markets.
Whether it's for Household Appliances in Brazil or Agricultural Machinery in the US, we provide specialized lubrication and sealing options tailored to local climate conditions (humidity, dust, and temperature).
We understand the needs of large-scale OEMs. Our SILL and NETB brands offer OEM/ODM flexibility, allowing global enterprises to integrate our high-precision components into their branded equipment.
Versatile, self-retaining bearings with deep raceways for radial and axial loads.
Separate bearings with tapered raceways for high-load capacity.
Designed for large one-way axial loads with varying contact angles.
Compact structure for high rotation precision under radial loads.
GCr15 is a high-carbon chromium bearing steel that provides an optimal balance of hardness (HRC 60-65) and fatigue life, making it the industry gold standard for durability.
The "ZZ" suffix indicates that the bearing is equipped with two non-contact metal shields. This provides protection against dust and retains factory-applied grease while maintaining high-speed capabilities.
We employ a 5-step inspection process: raw material initial-inspection, operator self-check, inspector full-check, chief inspector sampling, and final ex-factory inspection.
Yes. We offer localized support by selecting specific greases (e.g., Kyodo Yushi or Mobil) depending on whether the bearing is used in arctic conditions or tropical industrial zones.
Due to our strategic location near Ningbo and Shanghai ports and our expanding capacity, we offer some of the most competitive lead times in the industry, typically ranging from 15 to 45 days depending on customization.
Absolutely. We manufacture under our SILL and NETB brands, but we also offer comprehensive OEM services for global companies looking to build their own brand value.
SILL BEARING FACTORY is dedicated to the philosophy of "people-oriented, future-creating." Our mission is to provide high-precision rotational solutions that empower global industries. From household appliances to medical instruments and sports machinery, our products are engineered for low noise, low vibration, and maximum service life.
With our expansion into the Anhui TOPB factory, we are reinforcing our commitment to being a premier China 6208 ZZ bearing manufacturer, capable of serving the complex needs of the global market with integrity and sincerity.
