개요: Follow along for a hands-on demonstration that highlights performance points of the Sapphire Through Hole Bearing Custom Precision Optical Bearings. This video showcases the exceptional hardness, wear resistance, and ultra-high dimensional precision of these custom bearings, ideal for demanding motion-control and micro-mechanical systems.
관련 제품 특징:
  • Superior hardness and wear resistance with a Mohs scale rating of 9.
  • Ultra-high dimensional precision with hole diameter tolerance of ±0.005-0.02 mm.
  • Excellent chemical and thermal stability, resistant to temperatures up to 1,000°C+.
  • Customizable geometry including through-hole size, outer diameter, and thickness.
  • Precision drilling and double-side lapping ensure smooth, vertical through-holes.
  • CNC profiling and chamfering for improved assembly compatibility.
  • Widely used in optical instruments, semiconductor equipment, and medical devices.
  • Available in transparent, ruby red, and blue sapphire materials.
자주 묻는 질문:
  • Can you customize non-standard hole shapes like oval or tapered?
    Yes, we offer ultrasonic, CNC, and laser machining for special-shape through-holes.
  • What is the minimum hole size available?
    We can achieve 0.2 mm micro-through-holes depending on thickness and aspect ratio.
  • Can sapphire bearings replace metal or ceramic bearings?
    For low-friction, high-precision, and ultra-clean environments, sapphire bearings outperform metal and common ceramics.
