R12ZZST Bearing Product Overview & Core Advantages
The R12ZZST is a high-performance single row deep groove ball bearing designed for precision applications requiring reliable radial load capacity. Manufactured to ABEC 1 | ISO P0 tolerance standards, this inch-series bearing delivers consistent performance in demanding industrial environments. Its shielded construction provides effective contamination protection while maintaining smooth operation. With a chrome steel construction throughout all components, the bearing offers excellent durability and wear resistance, making it ideal for applications where precision and longevity are critical.
R12ZZST Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| R12 | Bearing series designation with specific dimensions | Standardized inch-series bearing for compatibility |
| ZZ | Double shielded construction on both sides | Enhanced contamination protection and grease retention |
| ST | Chrome steel construction for all components | Superior corrosion resistance and mechanical strength |
R12ZZST Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables excellent radial load capacity (2477 lbf dynamic / 1177 lbf static) while accommodating moderate axial loads in both directions.
Double Shielded Protection: ZZ shields provide effective sealing against contaminants while minimizing friction, contributing to the limiting speed of 17,000 rpm.
Precision Manufacturing: Built to ABEC 1 | ISO P0 tolerance standards with CN clearance, ensuring consistent performance and smooth operation across the entire temperature range (-30° to 120°C).
Material Excellence: All-chrome steel construction (rings, balls, and cage) provides uniform thermal expansion characteristics and excellent resistance to wear and corrosion.
