2.Structure Type: The inner ring has a spherical raceway, the outer ring has double ribs, with double-row rollers + stamped steel / brass cage, and it is open / sealed.
3.Size Range: Inner diameter 20 - 800mm, outer diameter 47 - 1200mm, width 16 - 200mm.
4.Material: Inner ring / outer ring: GCr15 bearing steel (conventional / ordinary models), 42CrMo (for heavy-load models), rollers: GCr15 bearing steel, cage: stamped steel / brass.
5.Precision: P0/P6 level.
6.Common Inner Tapered Hole: For inner diameters ≥ 50mm, a 1:12 tapered hole can be optionally selected, and for small inner diameters (< 50mm), most are straight holes.
7.Application Fields: Heavy-duty electric motors, reducers, port cranes, paper-making machinery.
8.Key Inspection Items: Consistency of double-row roller arrangement, self-aligning performance, radial load-bearing capacity.

Product Description

Double Row Spherical Roller Bearings for Extreme Load & High-Temperature Metallurgical Applications

Customizable up to φ5000mm | 150℃ Resistance | 30+ Years of Industrial Expertise

When your machinery faces heavy radial loads, misalignment challenges, or extreme temperatures, Double Row Spherical Roller Bearings deliver unmatched reliability. Designed with two rows of symmetrical rollers and a spherical outer ring raceway, these bearings compensate for shaft deflections up to ±2.5°, making them ideal for metallurgical, port, and medical equipment. At LUOYANG INNO, we’ve spent three decades refining their performance to handle 500kN+ radial loads and 150℃ environments—ensuring your operations stay productive.

Key Features

  • Thermal Mastery: Specialized heat treatment and 42CrMo alloy steel prevent deformation in metallurgical furnaces up to 500℃.
  • Load Capacity: Optimized roller alignment distributes stress evenly, extending bearing lifespan under heavy loads.
  • Agile Logistics: Modular production cuts lead times by 30% for custom bearing sizes up to φ5000mm.

Industry-Proven Applications

  • Metallurgy & Mining: Double Row Spherical Roller Bearings withstand 500℃ furnace temperatures, reducing unplanned downtime by 40%.
  • Port Machinery: Wear-resistant coatings for crane slewing rings achieve 100,000+ hours in high-humidity environments.
  • Medical Equipment: P4-grade precision and <35dB noise ensure smooth MRI rotor operation.

Quality & Support

Every bearing undergoes 3-stage quality control, including raw material purity checks and final load/heat endurance tests. We provide IoT-enabled wear monitoring and 24/7 technical guidance on lubrication.

FAQs

Q: How do your bearings handle 500℃ environments?
A: We use 42CrMo alloy steel and secondary carburizing to prevent micro-cracks under thermal stress in Double Row Spherical Roller Bearing applications.

Q: Can you customize bearings for non-standard machinery?
A: Yes! We’ve delivered φ5000mm bearings for vintage rolling mills within 20 days.

Q: What reduces noise in medical-grade bearing products?
A: Precision grinding (P4 grade) and brass cages dampen vibrations, achieving <35dB operation.
