310-2ZNR Bearing Product Overview & Core Advantages
The 310-2ZNR is a single row deep groove ball bearing engineered for high-performance industrial applications requiring reliable radial load capacity and robust operation. This shielded bearing features an integral snap ring on its outer ring, facilitating secure axial location within a housing and simplifying assembly. Pre-lubricated with grease, it offers a broad operating temperature range and is designed for moderately high speeds, making it an excellent choice for applications demanding compact design, ease of installation, and long-term reliability without frequent maintenance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 310 | Basic bearing series, defining the standard boundary dimensions (Bore: 50 mm, OD: 110 mm, Width: 27 mm). |
| 2Z | Bearing is equipped with non-contact shields on both sides. This provides effective protection against contamination while allowing for high limiting speeds. |
| N | Signifies a snap ring groove on the outer ring. |
| R | Indicates that the bearing is supplied with a snap ring fitted in the groove, ready for installation. |
310-2ZNR Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing delivers a high radial dynamic load rating of 14,478 lbf and a radial static load rating of 11,690 lbf, ensuring durability under significant stress.
- Simplified Housing Design & Axial Location: The integrated snap ring eliminates the need for complex housing shoulders or end caps, reducing component count, assembly time, and overall system cost.
- Contamination Protection & Maintenance-Free Operation: The 2Z shields effectively retain the factory-applied grease and protect the rolling elements from dust and debris, enabling a long service life with minimal maintenance.
- Optimized for Speed & Precision: Built to P0 tolerance class with standard CN radial internal clearance, this bearing provides consistent performance and is capable of operating at a limiting speed of 5,600 rpm.
