6219-Z Bearing Product Overview & Core Advantages
The 6219-Z is a single row deep groove ball bearing designed for high-performance industrial applications requiring reliable radial load capacity and consistent operation. Featuring shielded construction on one side (Z-type), this precision bearing offers excellent contamination protection while maintaining smooth rotation. Manufactured with chrome steel rings and balls combined with a stainless steel cage, it delivers superior durability and corrosion resistance. The bearing's P6 tolerance class ensures precise dimensional accuracy, making it ideal for applications demanding high rotational accuracy and long service life.
Model Code Detailed Breakdown

| 6219 | Basic bearing series with 95mm bore, 170mm OD | Standard deep groove ball bearing dimensions |
| -Z | One-side shielded (non-contact) | Effective contaminant protection with minimal friction |
6219-Z Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The deep groove raceway design enables efficient handling of radial dynamic load rating up to 25,628 lbf and radial static load rating of 18,322 lbf, providing reliable performance under substantial operational stresses.
Precision Engineering: Manufactured to P6 tolerance class with bore diameter tolerance of -0.015mm to 0 and outside diameter tolerance of -0.018mm to 0, ensuring precise fitment and minimal runout for applications requiring high rotational accuracy.
Enhanced Durability: The combination of chrome steel rings and balls with a stainless steel cage provides excellent wear resistance and dimensional stability, while the standard CN radial internal clearance ensures optimal performance across various operating conditions.
Temperature Resilience: Operating temperature range of -30°C to 120°C with factory-applied grease lubrication, making it suitable for diverse industrial environments without requiring frequent re-lubrication.
