217-2Z Bearing Product Overview & Core Advantages
The 217-2Z is a single row deep groove ball bearing designed for high-performance industrial applications requiring reliable operation under radial loads. Its shielded construction (2Z suffix) provides effective contamination protection while the pre-lubricated design ensures immediate operation and extended service life. Manufactured to P0 tolerance class with CN radial clearance, this bearing delivers consistent performance in demanding environments with an operating temperature range of -30° to 120°C.
Model Code Breakdown

| 2Z | Double-sided steel shields | Effective contaminant exclusion while maintaining high-speed capability |
217-2Z Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The single row deep groove raceway design enables efficient handling of radial dynamic load ratings of 21,762 lbf and static load ratings of 22,481 lbf, making it suitable for moderate to heavy-duty applications.
Enhanced Operational Efficiency: The nylon cage contributes to reduced friction and vibration, supporting a limiting speed of 3,900 rpm. Combined with chrome steel rings and balls, this ensures smooth operation and extended service life.
Maintenance-Free Operation: The double-shielded (2Z) construction with factory-applied grease lubrication provides sealed-for-life performance, eliminating the need for relubrication in many applications.
