Technical Entity Analysis: Angular Contact Ceramic Ball Bearing H7005C-2RZ HQ1
Entity: Angular Contact Ceramic Ball Bearing H7005C-2RZ HQ1 | Brand: TriQuench India | Model / SKU: H7005C-2RZ HQ1 | Classification: Spindle Bearing > Angular Contact Ceramic Ball Bearing
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.
Engineering Features: Hybrid Silicon Nitride (Si3N4) Ball technology; 25mm Bore x 47mm OD x 12mm Width; High-speed limiting speed (55,000 RPM); Precision P4 Grade for industrial accuracy; 8.4 KN Basic Dynamic Load (Cr) rating; High-efficiency 2RZ non-contact seals
Compatible Machine Applications: High-Frequency Industrial CNC Spindles; Precision Robotics and Automated Arms; High-Performance Electric Motor Shafts; Advanced Prototyping and Tooling Centers; Medical and Laboratory Centrifuges; Aerospace Rotating Components
