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.

Product Description

Double Angular Contact Bearing: Precision Engineered for Extreme Performance

When you need bearings that handle bidirectional axial and radial loads without compromising space or durability, our double angular contact bearing solutions deliver unmatched reliability. Designed for high-load, high-speed, and high-precision applications—from medical robotics to metallurgical presses—these angular contact ball bearings combine 30 years of engineering expertise with cutting-edge materials to outperform industry standards.

Technical Specifications

Parameter Specification
Size Range Standard (φ20–φ2000mm) or custom up to φ5000mm bearing dimensions
Load & Precision 40–60% higher load capacity; P4/P2 precision (ISO 492) for high-accuracy ball bearings
Materials & Hardness High-purity SUJ2 steel (60–64 HRC) or corrosion-resistant alternatives for long-life bearings
Sealing & Temp Contact/non-contact seals; Stable thermal performance from -50°C to 150°C (up to 500°C custom)

Key Advantages

  • Enhanced Load Capacity: Higher bidirectional axial and radial load tolerance than standard angular contact bearings.
  • Extreme Environment Resilience: Specialized heat treatment maintains dimensional stability in heavy-duty double row angular contact ball bearings.
  • Rapid Customization: Non-standard custom bearings up to φ5000mm delivered in 15–20 days via modular manufacturing.

Built for Your Industry's Demands

  • Metallurgy & Heavy Machinery: Bainite-treated steel bearings resist thermal stress and contamination in smelting equipment.
  • Port & Marine Equipment: Impact-resistant designs with brass cages and saltwater-proof seals extend crane bearing service life by 30%.
  • Medical & Precision Engineering: Ultra-low noise (<15 dB) and P4 precision ensure error-free operation in MRI scanner ball bearings.

Quality Assurance & Logistics

Every double angular contact bearing undergoes spectrometer material testing, CNC coordinate dimensional checks (±2μm tolerance), and vibration profiling. Standard angular contact ball bearings ship in 48 hours.

FAQs

Q: How do your bearings handle φ3000mm+ custom sizes so quickly?
A: Modular manufacturing cuts production time. We pre-machine components enabling rapid assembly of custom angular contact bearings.

Q: What ensures P4 precision in medical-grade ball bearings?
A: Precision grinding, high-purity steel, and triple-stage QC validating noise, vibration, and radial runout (±0.002mm) across all bearings.

Q: Can I get double angular contact bearings for high-impact port cranes?
A: Yes! Our brass cages and tempered steel absorb heavy shock loads, extending crane bearing lifespan by 30%.
