210-ZNR Bearing Product Overview & Core Advantages
The 210-ZNR is a single row deep groove ball bearing designed for exceptional radial load capacity and reliable operation. This metric bearing features a shielded design on one side and a unique snap ring on the outer ring, providing a secure axial location and simplifying housing design. Manufactured from high-grade chrome steel with a stainless steel cage, it offers robust performance, extended service life, and is pre-lubricated with grease for immediate use. Its P0 tolerance class and CN radial clearance make it a versatile and cost-effective solution for a wide range of industrial applications requiring precision and durability.
Model Code Breakdown
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 210 | Standard bore diameter (50 mm) and dimension series. | Interchangeable with industry-standard bearings. |
| Z | One side shielded. | Protects against contamination from one side while allowing for grease purging. |
| NR | Snap ring groove and snap ring fitted on the outer ring. | Provides positive axial location, eliminates the need for a complex housing shoulder, and reduces assembly time and cost. |
210-ZNR Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove construction and high-quality chrome steel components provide a high radial dynamic load rating of 8790 lbf and static load rating of 7756 lbf, ensuring stable performance under significant stress.
- Simplified Assembly with Snap Ring: The integrated snap ring (fitted) acts as a ready-to-use outer ring locating feature. This design simplifies the adjacent housing structure, saves space, and secures the bearing axially without additional components.
- Contamination Protection & Lubrication: The shielded side effectively retains lubricant and excludes larger contaminants. Combined with pre-applied grease, this ensures long-term, maintenance-free operation within a broad temperature range of -30° to 120 °C.
- Optimized for Speed: The lightweight and durable stainless steel cage maintains ball alignment and stability, contributing to a high limiting speed of 8,000 rpm for efficient operation.
210-ZNR Bearing Typical Application Areas
This bearing is ideally suited for applications requiring reliable radial support and simplified axial fixation. Common uses include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
