Advanced Engineering Analysis: Angular Contact Ceramic Ball Bearing H7005C-2RZ HQ1
Brand: TriQuench India | Model: H7005C-2RZ HQ1 | Classification: Spindle Bearing > Angular Contact Ceramic Ball Bearing > High Precision Series
The H7005C-2RZ HQ1 is a high-performance hybrid angular contact ball bearing engineered for precision industrial applications requiring extreme rotational speeds and thermal stability. By combining high-carbon chrome steel rings with aerospace-grade Silicon Nitride (Si3N4) ceramic balls, this bearing achieves a grease-lubricated limiting speed of 55,000 RPM. The 25mm bore and 47mm outside diameter make it the industry standard for high-frequency CNC spindles, precision robotics, and high-performance electric motors. Ceramic balls are 58% lighter than steel, significantly reducing centrifugal forces and friction-induced heat at high velocities. Certified to P4/HQ1 precision standards, this 70-gram bearing offers exceptional wear resistance and electrical insulation, ensuring long-lasting reliability in demanding machining environments.
Technical Core: Rated for industrial-grade output, maximum rotational velocity of high-performance, operating voltage of 220V/380V, with Water/Air Cooled thermal stabilization.
