As a leading manufacturer since 2014, Henan San Kuang Machinery Technology leverages our 10,000-30,000 sqm factory and ISO-certified processes to deliver angular contact bearings engineered for CNC precision. With over $2.5M annual exports to global markets including North America and Europe, our bearings ensure unmatched accuracy in high-speed machining applications. The optimized design minimizes friction while maximizing rigidity – critical for maintaining micron-level tolerances in industrial automation.
Core Technical Advantages:
Raceway geometry optimized for axial/radial load distribution
Super-finished surfaces (Ra ≤ 0.05μm) reduce vibration by 40%
Pre-lubricated with high-temperature grease for 20,000+ hour service life
Interchangeable with SKF/FAG series for easy retrofitting
Performance specifications vary by model:
| Model Series | Inner Diameter (mm) | Max Speed (rpm) | Contact Angle |
|---|---|---|---|
| 7000C | 10-100 | 18,000 | 15° |
| 7200B | 15-120 | 15,000 | 25° |
| 7300AC | 20-150 | 12,000 | 40° |
Clients report 30% longer tool life and 0.002mm runout consistency in CNC mills. The triple-lip sealing prevents coolant ingress – ideal for wet machining environments. Custom preload settings available to match spindle requirements.
Backed by 15+ international certifications including ISO9001 and OHSAS18001, our bearings ship globally from Shanghai/Qingdao ports. With 51-100 skilled technicians ensuring rigorous QA, we serve 90+ countries across Oceania to Eastern Europe.
