Sealed Spherical Roller Bearings

1.Product Introduction: Double-row self-aligning roller bearings with contact seals, with dust-proof and waterproof performance of IP54 - IP65, suitable for humid and dusty working conditions.
2.Structure Type: The inner ring has a spherical raceway, the outer ring has double ribs, with double-row rollers + stamped steel cage, and there are nitrile rubber sealing rings (2RS) on both sides.
3.Size Range: Inner diameter 30 - 500mm, outer diameter 62 - 800mm, width 20 - 150mm.
4.Material: Inner ring / outer ring: GCr15 bearing steel, rollers: GCr15 bearing steel, cage: stamped steel, seals: nitrile rubber / fluororubber.
5.Precision: P0/P6 level.
6.Common Inner Tapered Hole: For inner diameters ≥ 50mm, a 1:12 tapered hole can be optionally selected, and most of the small inner diameters are straight holes.
7.Application Fields: Agricultural machinery, mining machinery (with dust), automobile chassis (in humid conditions), water pumps.
8.Key Inspection Items: Sealing protection performance, self-aligning flexibility, radial clearance.

Product Description

High-Performance Sealed Spherical Roller Bearings for Extreme Industrial Environments

In harsh industrial environments where dust, moisture, and heavy loads threaten equipment longevity, sealed Spherical Roller Bearings are the ultimate defense. At LUOYANG INNO BEARING, we specialize in designing double-row self-aligning bearings with advanced sealing systems that outperform standard models. With IP54 to IP65 protection, our bearing products thrive in cement plants, mining sites, and metallurgical furnaces—saving you costly downtime and maintenance.

Key Advantages

  • Multi-Layer Sealing: Nitrile rubber or fluoropolymer seals block contaminants while retaining lubrication in our sealed Spherical Roller Bearings.
  • Heavy-Duty Resilience: GCr15 steel construction handles radial loads up to 450kN.
  • Self-Aligning Design: ±2.5° misalignment compensation for high-vibration bearing applications.

Technical Specifications

Industry-Proven Applications

  • Mining Crushers: IP65 seals prevent rock dust ingress in high-vibration bearing zones.
  • Steel Mill Conveyors: Spherical Roller Bearings withstand 150°C temperatures and molten debris.
  • Agricultural Machinery: Waterproof seals endure muddy, high-moisture conditions.
  • Port Cranes: Saltwater-resistant fluoropolymer seals reduce bearing corrosion.

Quality & Logistics

Every sealed bearing unit undergoes IP6X dust/water testing and 500-hour lifespan simulation. We offer 48-hour shipping for standard models and 20-day delivery for φ3000mm custom orders.

FAQs

Q: Can you integrate sensors into sealed Spherical Roller Bearings for condition monitoring?
A: Yes! We embed temperature/vibration sensors without compromising IP ratings.

Q: How do your bearings reduce maintenance costs?
A: Our seals retain grease 3x longer, cutting bearing relubrication cycles by 40%.

Q: What if I need bearings for acidic environments?
A: Specify our PTFE-coated seals and stainless steel cages for superior chemical resistance.
