6334/HC5C3PS0VA970 Bearing Product Overview & Core Advantages
The 6334/HC5C3PS0VA970 is a single row deep groove ball bearing engineered for exceptional performance in demanding industrial applications. This precision bearing is distinguished by its hybrid ceramic construction, featuring Silicon Nitride (Si3N4) balls and chrome steel rings. This combination delivers superior performance, including higher speed capabilities, reduced friction, and extended service life compared to all-steel bearings. Its open design and C3 radial internal clearance make it suitable for applications with thermal expansion or heavy interference fits, ensuring reliable operation under radial loads.
6334/HC5C3PS0VA970 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6334 | Standard deep groove ball bearing series with 170mm bore, 360mm OD. |
| HC5 | Hybrid Ceramic: Signifies the use of Silicon Nitride (Si3N4) ceramic balls. |
| C3 | Radial internal clearance greater than normal (C3 group). |
| PS0 | Cage design/type designation (Chrome Steel pressed cage). |
| VA970 | Vendor-specific code, often related to special manufacturing processes or quality checks. |
6334/HC5C3PS0VA970 Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The use of Silicon Nitride balls provides significant advantages, including lower density (reducing centrifugal forces), higher stiffness, electrical insulation, and the ability to operate with minimal lubrication. This makes it an excellent high-speed bearing.
Robust Load Capacity: With a dynamic load rating of 7014 lbf and a static load rating of 76435 lbf, this bearing is built to handle significant radial loads in demanding environments.
Optimized for Precision and Stability: Manufactured to ABEC 1 | ISO P0 tolerance class, it ensures consistent and reliable performance. The C3 clearance accommodates thermal expansion in shafts and housings, preventing preload and potential seizure.
High-Temperature Capability: The specified temperature range of -30°C to 150°C allows for operation in a wide variety of industrial conditions.
6334/HC5C3PS0VA970 Bearing Typical Application Areas
