What is the limiting speed of the H7009C-2RZ HQ1 with grease?

This hybrid ceramic bearing is rated for a limiting speed of up to 33,000 RPM when used with high-speed grease lubrication.

How do ceramic balls improve bearing performance?

Ceramic balls (Si3N4) are harder, smoother, and much lighter than steel. They generate 40% less heat, reduce centrifugal force at high speeds, and are naturally resistant to corrosion and electrical conductivity.

What does the 2RZ seal do?

The 2RZ refers to double non-contact seals. They provide a barrier against dust and contaminants while allowing the bearing to reach its maximum RPM without the friction and heat of a standard contact seal.

Angular Contact Ceramic Ball Bearing H7009C-2RZ HQ1

SKU / Model: H7009C-2RZ-HQ1

Power RatingIndustrial Grade

Max SpeedUp to 60,000 RPM

Cooling MethodStandard Cooled

Interface / SpecP4 Precision Grade

The H7009C-2RZ HQ1 is a high-performance hybrid angular contact ball bearing designed for advanced spindle systems requiring exceptional speed and thermal stability. By pairing high-carbon chrome steel rings with aerospace-grade Silicon Nitride (Si3N4) ceramic balls, this bearing reaches a limiting speed of 33,000 RPM with grease lubrication. The ceramic balls provide a 58% reduction in density compared to steel, drastically lowering centrifugal forces and internal heat generation during operation.
