2.Structure Type: The outer ring has a tapered raceway (high - precision), the inner ring is separable (conventional precision), with a single - row of rollers + cage.
3.Size Range: Inner diameter 15 - 500mm, outer diameter 32 - 1000mm, width 10 - 200mm.
4.Material: Inner ring/Outer ring/Rollers: GCr15/GCr15SiMn/20Cr2Ni4A, cage: stamped steel / brass.
5.Precision: The outer ring is P5 level, and the inner ring is P6 level.
6.Application Fields: Machine tool spindle bearing seats, automobile hub bearing seats.
7.Key Inspection Items: Outer - ring dimensional accuracy, taper surface fitting degree, bearing seat fit clearance.

Product Description

High-Performance Cup Tapered Roller Bearings for Extreme Industrial Applications

Customizable Solutions for Heavy Loads (Up to 5000kN), High Temperatures (500°C+), and Ultra-Low Noise (<35dB)

When your machinery demands precision under pressure, Cup Tapered Roller Bearings deliver unmatched performance. Designed to handle combined radial and axial loads, these bearings excel in harsh environments—from scorching steel mills to high-precision medical imaging systems. At LUOYANG INNO BEARING CO., LTD, we engineer solutions that endure extreme temperatures, shock loads, and corrosive conditions while maintaining optimal efficiency. With over 30 years of expertise, our bearings are trusted by industries where downtime isn't an option.

Why Choose Our Cup Tapered Roller Bearings?

  • Built for Extreme Conditions: GCr15/GCr15SiMn steel construction offers 20% longer fatigue life, operating seamlessly from -50°C to +500°C.
  • Industry-Specific: Metallurgy-grade bearings use graphite-lubricated cages for 500°C stability; medical-grade units achieve <35dB noise via electropolished surfaces.
  • Rapid Delivery: 1,000+ standard bearing SKUs ready for 48-hour shipment; modular production cuts custom lead times by 30%.

Quality Assurance

Every bearing undergoes vibration, hardness, and fatigue life checks to ensure a 99.9% reliability rate. We offer full end-to-end support, from CAD modeling to on-site installation.

FAQs

Q: Can your bearings handle OD >5000mm with P4 precision?
A: Yes! We've delivered φ5200mm non-standard bearings for hydropower turbines, maintaining P4 precision through proprietary grinding techniques.

Q: How do you achieve <35dB noise levels?
A: Precision-ground rollers and brass cages minimize friction. Medical-grade bearings are further polished to Ra 0.05μm.

Q: Do you support legacy machinery retrofits?
A: Our engineers provide free fitment analysis and CAD adaptations for outdated equipment.
