30+ Years of Precision Engineering | Custom Sizes up to φ5000mm | P4-Grade Accuracy & 48-Hour Fast Delivery
When your machinery demands durability and precision, Deep Groove Ball Bearings are the backbone of smooth operation. At LUOYANG INNO BEARING CO., LTD, we specialize in manufacturing bearings that excel under heavy loads, high temperatures, and rigorous industrial demands. With over three decades of expertise, our solutions combine advanced materials, precision manufacturing, and tailored designs to keep your equipment running longer and quieter.

1. Metallurgy & Heavy Machinery
Our bearings withstand extreme heat (up to 500°C) and heavy loads in rolling mills and forging equipment. The DGBB-HD Series offers reinforced cages and dynamic load ratings 1.5x higher than standard models.
2. Port & Construction Machinery
Corrosion-resistant coatings and IP69K sealing protect against saltwater and dust in cranes and conveyor systems.
3. Medical & Food Processing
Stainless steel Deep Groove Ball Bearings with USP Class VI grease meet strict hygiene standards for MRI machines and packaging lines.
4. Automotive & Appliances
Low-noise (<18dB) DGBB-XT Series bearings enhance efficiency in transmissions and HVAC systems.
✅ End-to-End Customization
Need non-standard dimensions (e.g., φ3000mm+)? Our R&D team delivers prototypes in 7–10 days and full production in 15–20 days.
✅ Agile Global Supply Chain
1,000+ standard bearings in stock | 48-hour dispatch to EU/NA | Modular production for 30% faster lead times.
✅ Proven Quality
99.9% qualification rate via 12+ tests, including vibration analysis and lifespan simulations (50,000+ hours).
✅ Full-Lifecycle Support
From CAD design assistance to IoT-based wear monitoring, we optimize bearing performance and reduce downtime.
Every product undergoes:
1. Material Screening: Traceable steel grades and hardness checks (HRC 60-64).
2. In-Process Checks: Precision grinding tolerances (±0.001mm).
3. Final Validation: 100% testing for noise, vibration, and load capacity.
Certifications: ISO 9001, IATF 16949 (automotive), and RoHS compliance.

1. Can your bearings handle frequent start-stop cycles in automotive applications?
Yes! Our DGBB-XT Series uses hybrid ceramic balls and reinforced cages for 200,000+ cycles.
2. Do you offer food-grade lubrication options?
Absolutely. We use NSF H1-certified greases for food processing equipment.
3. How do you ensure fast delivery for custom sizes?
Modular production and regional hubs cut lead times to 70% of industry averages.
4. What makes your medical-grade bearings unique?
Stainless steel construction and ultra-clean packaging eliminate particle contamination.
