Hybrid Spindle Bearings HCB7009-C-T-2RSD-P4S-UL

Hangzhou Huaxing Kechuang Holding Group Co., Ltd. is one of the leading manufacturers and suppliers of hybrid spindle bearings hcb7009-c-t-2rsd-p4s-ul in China. As we have world-leading production equipment and strong manufacturing capabilities, we warmly welcome you to buy bulk high quality bearings at competitive price from our factory.

Hybrid Spindle Bearings-HCB7009C-2RSD-T-P4S-UL

1. 1. Ultra-Light Weight & Reduced Centrifugal Load

   Ceramic balls feature low density, weighing roughly 60% less than standard steel balls. This drastically cuts centrifugal force generated under high-speed rotation.

   2. Superior Hardness & Extended Service Lifespan

   Boasting higher hardness than bearing steel, ceramic balls deliver outstanding wear and fatigue resistance, effectively prolonging the overall service life of bearings.

   3. Minimal Thermal Deformation for Stable Preload

   With an ultra-low thermal expansion coefficient, ceramic components barely deform when running at high RPM, maintaining consistent bearing preload throughout operation.

   4. Electrical Insulation to Eliminate Electric Corrosion

   As non-conductive media, ceramic balls block stray electric currents, eradicating electrical pitting damage on bearing raceways caused by electric corrosion.

   5. Higher Speed Threshold for High-Speed Spindles

   Hybrid bearings fitted with ceramic balls support a remarkably higher DN value compared to all-steel spindle bearings, perfectly suited for ultra-high-speed spindle equipment.

   6. Low Friction & Less Heat Accumulation

   The ultra-smooth surface of ceramic balls lowers rolling friction significantly, suppressing heat generation during rotation and helping spindles sustain stable precision long-term.

   7. Outstanding Anti-Corrosion Performance

   Ceramic materials outperform full steel structures in resisting humidity, weak acid erosion and oil degradation, delivering reliable anti-corrosion performance in complex working environments.

∗ 30 years of dedicated development

HXB now operates 6 subsidiaries, including 3 national high-tech enterprises and Zhejiang provincial science and technology enterprises. It owns 2 provincial-level high-tech R&D centers, 2 modern manufacturing bases - Hangzhou Yijia Precision Bearing Co., Ltd. and Zhejiang Ruiyang Bearing Technology Co., Ltd. - and employs more than 400 people, including over 80 professional R&D engineers.

∗ 2 high-tech R&D centers

∗ Two factories - Hangzhou YJB-precison bearing and Zhejiang Ruiyang Bearing( deep groove ball bearing)

∗ MES and SPC production management systems

∗ High-end equipment 

1. Hangzhou Factory - YJB

Hangzhou Yijia Precision Bearing, established in 2007, specializes in high-precision customized bearings with sizes ranging from Φ3mm to Φ300mm and precision grades up to P2 and P4.

• Production range: ID Φ5–Φ300mm
• Accuracy Classes: P2, P4, P5, P6
• Annual Output: 3,000,000 sets of precision bearings
• Production lines: 14

2. Huzhou Factory

This factory was relocated from Hangzhou( our headquter) to HUzhou in 2021. 

Deep groove ball bearings were the first bearing type manufactured by HXB since our establishment in 1995. We boast extensive manufacturing experience and a highly competent management team. Our current annual output of deep groove ball bearings reaches 3 million sets, and our products are well recognized for ultra-low noise and extended service life.

To keep pace with evolving industrial trends, we have expanded into emerging sectors and successfully developed a full lineup of bearings for new energy vehicles.
