Ceramic Angular Contact Bearings

1.Product Introduction: With silicon nitride ceramic as the rolling elements, they possess the characteristics of lightweight, high temperature resistance (≤ 400°C), non-magnetic, and corrosion resistance, suitable for precision transmission in harsh working conditions.
2.Structure Type: Inner ring / outer ring (steel angular contact raceway) + silicon nitride ceramic balls + brass or titanium alloy cage. Some inner rings are equipped with tapered holes (suitable for tight-fitting shaft systems).
3.Size Range: Inner diameter: 15 - 300mm, outer diameter: 40 - 500mm, width: 11 - 100mm.
4.Material: Inner ring / outer ring: GCr15/GCR15SIMN/ceramic, rolling elements (ceramic balls): silicon nitride (Si3N4), cage: brass (conventional) / titanium alloy (for high-temperature models).
5.Accuracy: Conventional P0 grade, precision models are of P6/P5/P4 grades.
6.Application Fields: Aero-engines, high-temperature motors, semiconductor equipment, chemical machinery, high-end medical instruments.
7.Key Inspection Items: Roundness of ceramic balls (≤ 0.001mm), conformity of raceway fitting, high temperature resistance performance (no deformation at 400°C), non-magnetic detection.

Product Description

High-Performance Ceramic Angular Contact Bearings for Extreme Industrial Demands

When your equipment operates in punishing environments, ceramic angular contact bearings deliver unmatched reliability. At LUOYANG INNO BEARING CO., LTD, we engineer these bearings to outperform steel counterparts with extended lifespan, lower heat generation, and zero magnetic interference. Designed as specialized angular contact ball bearings, they excel under severe thermal, mechanical, and chemical stress.

Technical Specifications

Parameter Specification
Rolling Element Material Silicon nitride (Si3N4) ceramic balls for extreme temperature stability
Temperature & Speed Limits Withstands up to 800°C without deformation; DN values up to 500,000 RPM
Precision & Size Range ABEC 7 / P4 precision (±0.002mm runout); Standard φ15mm to custom φ5000mm bearing sizes
Corrosion & Load Resistance Full-ceramic/hybrid options for acid/alkali resistance; 220% higher dynamic load capacity than standard ball bearings

Key Advantages

  • Extreme-Temperature Mastery: Si3N4 bearing balls handle thermal shock in continuous casting lines and furnace rollers.
  • Friction & Heat Reduction: Ceramic angular contact bearings run 40% cooler than all-steel designs at high RPM.
  • Corrosion & Non-Magnetic Immunity: Ideal for semiconductor vacuum chambers, medical autoclaves, and chemical processing bearings.

Applications That Demand More

  • Metallurgy: Ladle turrets exposed to extreme heat shocks and molten splash in heavy-duty bearing positions.
  • Medical Autoclaves: Steam sterilization cycles without corrosion or lubricant breakdown in medical ball bearings.
  • Semiconductor Etching: Vacuum-ready ceramic angular contact bearings resisting plasma erosion.

Quality Control & Delivery

Every bearing undergoes 12+ validation checks including fatigue simulation (ASTM F2094), thermal cycling (-60°C to 800°C), and noise profiling. We maintain 1,000+ standard models for 48-hour dispatch, with 15–20 day delivery for custom orders.

FAQs

Q: Can you make ceramic angular contact bearings for non-standard shaft sizes?
A: Yes! We specialize in sizes from φ15mm to φ5000mm, including custom tapered bore bearings.

Q: How do hybrid angular contact ball bearings reduce operational heat?
A: Ceramic balls minimize friction and centrifugal force, running significantly cooler than steel bearings at high speeds.

Q: What certifications apply to your ceramic bearings?
A: ISO 9001, ASTM F2094, and CE standards, with GOST or ATEX compliance available for critical thrust and radial bearing setups.
