Technical Entity Analysis: Angular Contact Ceramic Ball Bearing H7003C-2RZ HQ1
Entity: Angular Contact Ceramic Ball Bearing H7003C-2RZ HQ1 | Brand: TriQuench India | Model / SKU: H7003C-2RZ HQ1 | Classification: Spindle Bearing > Angular Contact Ceramic Ball Bearing
The H7003C-2RZ HQ1 is an ultra-precision hybrid angular contact ball bearing engineered for extreme high-speed machinery where rotational accuracy and thermal stability are critical. By combining premium high-carbon chrome steel rings with aerospace-grade Silicon Nitride (Si3N4) ceramic balls, this bearing achieves a staggering grease-lubricated limiting speed of 73,800 RPM. The 17mm bore and 35mm outside diameter make it the standard choice for high-frequency electric spindles, dental handpieces, and micro-machining centers. Ceramic balls are 40% less dense than steel, which virtually eliminates centrifugal ball loading and drastically reduces internal heat generation at extreme velocities. Certified to P4/HQ1 precision standards, this 40-gram bearing offers the ultimate combination of speed, durability, and electrical insulation.
Engineering Features: Hybrid Silicon Nitride (Si3N4) Ball technology; 17mm Bore x 35mm OD x 10mm Width; Extreme High-speed Limiting (73,800 RPM); Precision P4 Grade for industrial accuracy; 5.2 KN Basic Dynamic Load capacity; Lightweight 0.04 kg architecture
Compatible Machine Applications: Ultra-High Frequency CNC Spindles; Precision Dental and Medical Handpieces; High-Speed Micro-Routing and Engraving; Turbochargers and High-RPM Fans; Advanced Laboratory Centrifuges; Optical and Electronic Testing Equipment
