/ Double row angular contact ball bearings

double angular contact bearing

1.Product Introduction: It is the colloquial abbreviation for double-row angular contact ball bearings. With a compact structure, it is suitable for bidirectional combined load scenarios with limited space.
2.Structure Type: Inner ring + outer ring (with symmetrical double angular contact raceways) + double-row steel balls + stamped steel or brass cage, capable of independently bearing bidirectional forces.
3.Size Range: Inner diameter: 20 - 400mm, outer diameter: 47 - 600mm, width: 20 - 150mm.
4.Material: Inner ring / outer ring: GCr15/GCR15SIMN, rolling elements (steel balls): GCr15/GCR15SIMN, cage: stamped steel (conventional) / brass (precision).
5.Accuracy: Conventional P0 grade, precision models are of P6/P5/P4 grades.
6.Application Fields: Small and medium-sized motors, feed shafts of machine tools, automobile transmission systems, light industrial precision equipment.
7.Key Inspection Items: Bidirectional radial clearance (0.003 - 0.008mm), conformity of steel balls fitting, stability of the cage, installation adaptability.

Key Technical Advantages

  • Enhanced Load Capacity: 40–60% higher axial/radial load tolerance than standard angular contact bearings.
  • Extreme Environment Ready: Stable performance from -50°C to 150°C with specialized heat treatment.
  • Precision Grades: P4/P2 accuracy (ISO 492-certified) for surgical robotics and CNC machinery.
  • Rapid Customization: Non-standard sizes up to φ5000mm delivered in 15–20 days.

Built for Your Industry's Demands

Metallurgy & Heavy Machinery

Withstand 500°C temperatures and contamination-prone environments using carbide-free bainite-treated steel. Our bearings maintain ≤0.01% dimensional change under continuous thermal stress, reducing unplanned downtime in smelting equipment.

Port & Marine Equipment

Impact-resistant designs with brass cages and saltwater-proof seals extend service life by 30% in high-humidity crane operations.

Medical & Precision Engineering

Ultra-low noise (<15 dB) and P4-grade precision ensure error-free performance in MRI machines and robotic surgery arms.

Customization Made Simple

Configure your product in 5 steps:

  • Size: Standard (φ20–φ2000mm) or custom (up to φ5000mm).
  • Material: High-purity SUJ2 steel or corrosion-resistant alternatives.
  • Sealing: Contact/non-contact seals for dust, moisture, or chemical resistance.
  • Lubrication: Grease, oil, or solid-film options tailored to operating temperatures.
  • Precision: P0 (standard) to P4 (medical-grade).

Lead Time Advantage:

  • Non-standard orders: 15–20 days (vs. 70-day industry average).
  • Bulk standard orders: Shipped in 48 hours from 1,000+ in-stock SKUs.

Quality You Can Trust

Every double angular contact bearing undergoes triple inspection:

  • Material Testing: Hardness (60–64 HRC) and purity checks via spectrometry.
  • Dimensional Accuracy: ±2μm tolerance using CNC coordinate measuring.
  • Performance Validation: Vibration (<4.5 dB), lifespan (100,000+ hours L10), and load distribution tests.

Result: 99.9% ex-factory qualification rate (ISO 9001-certified processes).

FAQ

Q: How do your bearings handle φ3000mm+ custom sizes so quickly?

A: Modular manufacturing cuts production time by 70%. We pre-machine components for common configurations, enabling rapid assembly.

Q: What ensures P4 precision in medical-grade bearings?

A: Precision grinding, high-purity steel, and triple-stage QC—validating noise, vibration, and radial runout (±0.002mm).

Q: Can I get bearings for high-impact port cranes?

A: Yes! Our brass cages and tempered steel absorb shocks, extending lifespan by 30% in heavy-load scenarios.
