Core Advantages

  • Self-Aligning Design: Compensates for shaft misalignment up to 3°, ensuring smooth bearing operation.
  • High-Purity Materials: GCr15 steel construction guarantees optimal hardness (60-66 HRC) and fatigue resistance.
  • Rapid Customization: Standard bearing units available for 48-hour dispatch, with custom variants delivered in 15–20 days.

Industry-Proven Applications

  • Medical Imaging: P6-grade 22211 bearing precision (<35dB noise) ensures MRI/CT scanner stability.
  • Port Machinery: Optional triple-lip seals protect the bearing from heavy dust and high humidity.
  • Electric Motors: Self-aligning features reduce bearing maintenance costs by 30% in ventilation systems.

Quality & Lifecycle Support

Every bearing undergoes triple-stage testing, including spectrometry, vibration analysis (ISO 15242), and radial clearance validation to ensure 99.9% defect-free performance.

FAQs

Q: Can the 22211 bearing handle high-temperature environments?
A: Yes, we offer high-temperature bearing variants with synthetic PAO grease (-20°C to 150°C).

Q: What is the MOQ for customized bearing orders?
A: Minimum 10 units for custom designs (sealed/coated); standard bearing units have no MOQ.

Q: Do you provide installation support for your roller bearing products?
A: Absolutely—our engineers offer free 24/7 guidance on mounting, lubrication, and wear analysis.
