207SZZ-HNCR-HYB Bearing Product Overview & Core Advantages
The 207SZZ-HNCR-HYB is a single row deep groove ball bearing engineered for precision and durability in demanding applications. Constructed with stainless steel rings and ceramic silicon nitride balls, this bearing offers superior corrosion resistance and extended service life. Its shielded design provides effective protection against contaminants while maintaining low friction. With an ABEC 1 / ISO P0 tolerance class and a radial dynamic load rating of 6182 lbf, it delivers reliable performance for applications requiring high rotational accuracy and radial load capacity.
207SZZ-HNCR-HYB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| SZZ | Stainless Steel construction with ZZ (double shielded) seals | Excellent corrosion resistance and contaminant protection |
| HN | Hybrid Ceramic (Silicon Nitride) balls | Reduced friction, higher speed capability, and electrical insulation |
| CR | Chrome Steel cage | Enhanced durability and stability at high speeds |
| HYB | Hybrid bearing construction | Optimal combination of corrosion resistance and performance |
207SZZ-HNCR-HYB Bearing Structural Features & Performance Benefits
Hybrid Construction: The combination of stainless steel rings and ceramic balls provides exceptional corrosion resistance while reducing weight and improving high-speed performance. Ceramic balls have lower thermal expansion and higher stiffness than steel balls, contributing to more stable operation across the temperature range of -30° to 120°C.
Precision Engineering: Manufactured to ABEC 1 / ISO P0 tolerance standards with CN radial clearance, this bearing ensures consistent performance and smooth operation. The precise dimensional tolerances (bore: -0.012mm to 0, OD: -0.013mm to 0) guarantee proper fit and alignment in applications.
Shielded Protection: The double shielded (ZZ) design effectively excludes contaminants while maintaining low torque characteristics. This makes the bearing suitable for applications where maintenance-free operation is desired, though it operates without pre-lubrication.
Load Capacity: With a radial dynamic load rating of 6182 lbf and static load rating of 4946 lbf, this bearing handles significant radial loads while the hybrid construction allows for higher limiting speeds compared to all-steel equivalents.
