C - Contact Angle
C: 15° contact angle, optimized for ultra-high speed & low heat generation. The best angle choice for long-duration high-RPM spindle operation.
SN24 or HQ1- Hybrid Ceramic Material Code (Core Feature)
SN24: NSK exclusive code forSi₃N₄ silicon nitride ceramic balls + steel raceway hybrid structure
Features ultra-light weight, low thermal expansion, complete electrical insulation, ultra-low temperature rise, which is the key configuration for NSK ultra-high-speed HPS spindle bearings.
T - Cage Type
T: High-stability resin cage, ball-guided structure
High temperature resistance, low friction deformation, specially optimized for ceramic ball high-speed rolling guidance.
RV1 - Vibration & Noise Grade
RV1: Ultra-low vibration & ultra-low noise grade
Strict raceway roundness and surface roughness control, minimizes micro-jitter during ultra-high-speed operation, suitable for ultra-fine finishing processing.
P4 - Precision Grade
7016CSN24TRV1VDTP4 is an NSK HPS ultra-high-speed hybrid ceramic super-precision spindle bearing. With 15° high-speed angle, silicon nitride ceramic balls, resin high-speed cage, ultra-low vibration structure and P4 super precision, it is professionally designed for long-term continuous ultra-high-speed, low-temperature-rise, low-noise high-end finishing spindles.
Features
1. Hybrid build: Steel rings + Si₃N₄ ceramic balls
2. Lightweight ceramic cuts high-speed centrifugal load
3. High hardness, wear-proof & longer service life
4. Low thermal expansion, stable preload at high RPM
5. Insulated ceramic avoids stray current corrosion
6. Higher DN value for ultra-high-speed spindle use
7. Less friction & heat, sustain long-term precision
8. Better resistance to moisture, weak acid & oil aging
Applications
Applicable Machine Tools & Industrial Equipment
Combined with its core advantages of ultra-high speed, ultra-low vibration, low heat generation, electric insulation and long-cycle precision stability, this bearing is exclusively matched with high-end precision finishing equipment that requires continuous high-speed operation and strict surface machining quality:
High-speed Vertical & Horizontal Machining Centers – Especially HSK63/HSK80 high-speed spindle models for mold precision finishing, long-hour unmanned production.
Ultra-precision Grinding Machine Tools – Including surface grinders, internal/external cylindrical grinders, and tool grinders, supporting mirror-level fine grinding processing.
High-end High-frequency Spindle Equipment – Variable frequency high-power electric spindles used for metal high-speed cutting, drilling and tapping continuous finishing.
Mold High-precision Processing Machine Tools – Precision engraving and milling machines, high-speed finish milling machines for 3C mold, automotive mold and medical mold ultra-fine processing.
Precision Automation & Special Processing Equipment – High-speed precision rotating units for aerospace parts finishing, semiconductor auxiliary processing and high-precision testing equipment.
Application Exclusion: Not suitable for heavy-load roughing machines, impact-load equipment and dusty/poor-sealed industrial environments, as it is optimized for high-speed, light-medium load and high-cleanliness precision finishing scenarios.
