WBB1-8707-2Z Bearing Product Overview & Core Advantages
The WBB1-8707-2Z is a metric single row deep groove ball bearing engineered for precision and reliability in compact applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to efficiently handle radial loads while its shielded design retains lubrication and protects against contaminants. This combination makes it an ideal, long-lasting component for applications demanding high reliability and minimal maintenance in a small footprint.
WBB1-8707-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| WBB1-8707 | Basic bearing designation, defining the core dimensions: 7mm bore, 13mm OD, 4mm width. |
| 2Z | Signifies that the bearing is shielded on both sides. This provides effective protection against contaminant ingress while retaining the pre-applied grease, contributing to its maintenance-free characteristic. |
WBB1-8707-2Z Bearing Structural Features & Performance Benefits
- Compact and Robust Design: The single-row deep groove geometry and small cross-section (4mm width) make it suitable for space-constrained assemblies without sacrificing performance.
- Corrosion Resistance: Manufactured from stainless steel for rings, balls, and cage, this bearing is ideal for applications exposed to moisture or corrosive environments.
- Pre-Lubricated and Sealed: Filled with grease and fitted with non-contact shields (2Z), the bearing is ready for use and requires no relubrication, ensuring a long service life and reduced maintenance.
- Standard Precision: Manufactured to P0 tolerance class and standard CN radial internal clearance, it provides consistent and reliable performance for a wide range of general-purpose applications.
WBB1-8707-2Z Bearing Typical Application Areas
This bearing is commonly specified in:
- Small Electric Motors and Gearboxes
- Precision Instruments and Medical Devices
- Office Automation Equipment (e.g., printers, scanners)
- Radio Control Models and Drones
- Food and Beverage Handling Equipment (due to stainless steel construction)
