Double Row Self Aligning Ball Bearing

1.Product Introduction: With a double-row steel ball structure, its radial load-bearing capacity is 2 - 2.5 times that of the single-row ones, and it can compensate for installation deviations of ±2°, suitable for heavy-duty and installation error scenarios.
2.Structure Type: Inner ring (with optional cylindrical hole or tapered hole) + outer ring (with spherical raceway) + double-row steel balls + steel or brass cage. An isolation ring is set in the middle, and it features a thick-wall design.
3.Size Range: Inner diameter: 20 - 800mm, outer diameter: 47 - 1000mm, width: 18 - 200mm.
4.Material: Inner ring / outer ring: GCr15/GCR15SIMN/20Cr2Ni4A (42CrMo for heavy-duty models), rolling elements (steel balls): GCr15/GCR15SIMN, cage: steel (conventional) / brass (precision).
5.Accuracy: Conventional P0/P6 grades, heavy-duty precision models are of P5 grade.
6.Application Fields: Heavy-duty construction machinery (crushers), mining machinery (ball mills), large motors (above 20kW), port cranes.
7.Key Inspection Items: Consistency of double-row steel ball clearance, self-aligning angle (±2°), radial load-bearing capacity, strength of the outer ring (no cracks).

Product Description

Double Row Self Aligning Ball Bearings for Heavy Machinery & Precision Applications

When your equipment faces heavy radial loads, shaft misalignment, or extreme operating conditions, double row self aligning ball bearings deliver unmatched reliability. At LUOYANG INNO BEARING CO., LTD, we engineer these bearings with 30+ years of expertise to withstand high temperatures, compensate for ±2° installation errors, and handle 2.5x higher radial loads than single-row designs—all while reducing maintenance costs for heavy industrial equipment.

Where Our Bearings Excel

  • Metallurgy & Heavy Industry: Continuous casting machines and rolling mills with cyclic loads using heavy self aligning ball bearings.
  • Precision Machinery: High-speed robotics and diagnostic medical equipment requiring low-vibration ball bearings.
  • Mining & Construction: Crushers and conveyor systems in dusty environments driven by durable roller and ball bearings.

Quality Assurance & Support

Every double row self aligning ball bearing undergoes material spectrometry, high-precision raceway grinding (<0.001mm tolerance), and 72-hour load endurance testing. Standard bearings ship within 48 hours.

FAQs

Q: How do your double row self aligning ball bearings handle 500°C temperatures?
A: We use specialty alloy steel (such as 20Cr2Ni4A) and secondary tempering to prevent raceway deformation in high-heat bearings.

Q: Can you make self aligning bearings larger than φ1000mm?
A: Yes, we specialize in custom double row self aligning ball bearings up to φ5000mm with rapid 15–20 day delivery.

Q: What certifications apply to your ball bearings?
A: All bearings comply with ISO 9001, IATF 16949, and ASTM standards for heavy industrial applications.
