207-Z Bearing Product Overview & Core Advantages
The 207-Z is a single row deep groove ball bearing designed for robust performance in a wide range of industrial applications. Engineered to primarily handle radial loads, it features a shielded (Z-type) design on one side, offering effective protection against contaminant ingress while retaining lubricant. Manufactured with Chrome Steel rings and balls, and a lightweight Nylon cage, this bearing delivers a reliable balance of durability, high-speed capability (up to 10,000 rpm), and smooth operation. Its P0 tolerance class and standard CN radial internal clearance ensure consistent performance for general precision requirements.
Model Code Breakdown
| Model Segment | Interpretation | Technical Significance |
|---|---|---|
| 207 | Basic Bearing Number | Defines the standard boundary dimensions: 35mm bore, 72mm OD, 17mm width. |
| -Z | Shield Designation | Indicates a non-contact steel shield fitted on one side. This provides good contaminant exclusion with minimal impact on limiting speed. |
207-Z Bearing Structural Features & Performance Benefits
- Optimized Raceway Geometry: The deep groove raceways in both inner and outer rings are precision-ground to facilitate smooth rotation and efficient radial load distribution.
- Shielded Protection: The single-sided Z-shield acts as a primary barrier against dust and debris, extending bearing service life and reducing maintenance frequency in clean to moderately contaminated environments.
- Lightweight Nylon Cage: The cage guides the balls accurately, contributing to low noise, low vibration, and enhanced high-speed performance due to reduced centrifugal forces.
- Pre-lubricated & Ready-to-Use: The bearing is pre-filled with grease, making it immediately operational and suitable for applications where re-lubrication is difficult.
- Robust Material Construction: The use of Chrome Steel (Gcr15) for rings and balls provides high hardness, wear resistance, and a long operational lifespan under standard loads.
