Related Product Features:
  • Mohs hardness of 9 and Knoop hardness of 1,800 for superior wear resistance.
  • Low friction coefficient (0.10-0.15) reduces energy loss and enhances efficiency.
  • Corrosion-resistant alumina structure withstands harsh environments.
  • High-temperature tolerance up to 800°C with excellent thermal stability.
  • Lubrication-free design ensures long-term performance without maintenance.
  • Customizable geometries (spherical, conical, straight-hole) for diverse applications.
  • Ideal for low-load, high-sensitivity scenarios like watch escapements and meters.
  • Surface roughness Ra <0.3 nm for optical-grade precision.
Faqs:
  • Why are ruby bearings preferred for precision instruments?
    Ruby bearings offer exceptional hardness (Mohs 9), low friction, and wear resistance, ensuring precision and durability in high-stress applications.
  • What industries commonly use ruby bearings?
    Ruby bearings are widely used in watch movements, precision instruments, and aerospace due to their high-temperature tolerance and corrosion resistance.
  • Do ruby bearings require lubrication?
