Tapered Bore Bearing

1.Product Introduction: Self-aligning roller bearings with tapered inner holes, which can adjust the radial clearance through nuts, and are suitable for scenarios where the shaft system needs fine adjustment.
2.Structure Type: The inner ring has a tapered hole (1:12 or 1:30), the outer ring has double ribs, with double-row spherical rollers + cage, and it is open.
3.Size Range: Inner diameter 30 - 500mm, outer diameter 62 - 1000mm, width 20 - 200mm.
4.Material: Inner ring / outer ring: GCr15 bearing steel, rollers: GCr15 bearing steel, cage: stamped steel / brass.
5.Precision: P0/P6 level.
6.Common Inner Tapered Hole: 1:12 taper (suitable for most shaft systems), 1:30 taper (for precise fine adjustment).
7.Application Fields: Electric motor spindles, auxiliary rolls of rolling mills, heavy-duty fans, mining machinery.
8.Key Inspection Items: Tapered hole precision, adjustable range of radial clearance, self-aligning angle.

Core Advantages

  • Customization: Modular tooling supports tapered bore bearing production up to φ3000mm+ in just 15-20 days.
  • Extreme Conditions: Graphite lubrication slots and thermal-stable bearing designs minimize deformation at 150°C.
  • Global Logistics: 1,000+ standard bearing units ready for 48-hour dispatch from regional hubs.

Industry-Proven Applications

  • Metallurgy: Tapered bore bearing units feature thermal-stable raceways for 150°C continuous operation in backup rollers.
  • Port & Marine: Triple-layered seals protect bearing components against saltwater corrosion.
  • Medical & Precision: Ultra-low noise (<35dB) and non-magnetic ceramic bearing variants ensure MRI stability.

Quality & Lifecycle Support

Every bearing undergoes SGS-certified spectrometry and 12+ performance tests. We provide IoT monitoring software and 24/7 technical support for installation and predictive lubrication.

FAQs

Q: How do your tapered bore bearings handle 300°C environments?
A: We use high-purity steel with graphite-infused bearing raceways to maintain lubrication at extreme temperatures.

Q: Can you customize tapered bore bearings for 1000 RPM port cranes?
A: Yes! Our impact-resistant cages and balanced roller sets are optimized for high-speed, high-load scenarios.

Q: What ensures your bearing heavy-load reliability?
A: Each unit undergoes 3,000-hour accelerated lifespan tests under 150% rated load.
