Advanced Engineering Analysis: Angular Contact Ceramic Ball Bearing H7002C-2RZ HQ1
Brand: TriQuench India | Model: H7002C-2RZ HQ1 | Classification: Spindle Bearing > Angular Contact Ceramic Ball Bearing > High Precision Series
The H7002C-2RZ HQ1 is a pinnacle of micro-bearing engineering, designed for ultra-high-speed applications where standard steel bearings fail. By integrating aerospace-grade Silicon Nitride (Si3N4) ceramic balls with precision-ground steel rings, this hybrid bearing achieves an incredible grease-lubricated limiting speed of 81,700 RPM. The 15mm bore and 32mm outside diameter make it the ideal choice for micro-CNC spindles, high-frequency dental handpieces, and precision optical equipment. The ceramic balls are 58% lighter than steel, which virtually eliminates centrifugal ball loading and internal heat generation at extreme velocities. Certified to P4/HQ1 precision standards, this bearing offers unmatched thermal stability, low vibration, and natural electrical insulation for sensitive high-speed systems.
Technical Core: Rated for industrial-grade output, maximum rotational velocity of high-performance, operating voltage of 220V/380V, with Water/Air Cooled thermal stabilization.
