WBB1-8707 R-2Z Bearing Product Overview & Core Advantages
The WBB1-8707 R-2Z is a single row deep groove ball bearing designed for high performance in compact spaces. Engineered from stainless steel for superior corrosion resistance, this shielded bearing is pre-lubricated with grease, offering a robust, low-maintenance solution. Its key advantage lies in its ability to handle significant radial loads efficiently while operating at high speeds, making it an ideal choice for applications demanding reliability and long service life within a specified temperature range.
WBB1-8707 R-2Z Bearing Model Code Explained, Specifications & Naming Convention
- WBB1-8707: Base model number, indicating the bearing's core dimensions (7mm bore, 13mm OD).
- R: This suffix often denotes a flanged outer ring, which aids in precise axial location and simplifies housing design.
- 2Z: Signifies that the bearing is equipped with shields on both sides. This provides effective protection against contamination from solid particles while minimizing friction, contributing to the bearing's high limiting speed.
WBB1-8707 R-2Z Bearing Structural Features & Performance Benefits
The bearing's performance is a direct result of its precision construction:
- Robust Load Capacity: The single row deep groove raceway and stainless steel construction provide a high dynamic and static load rating for its compact size, ensuring reliable operation under demanding radial loads.
- High-Speed Capability: The combination of low-friction shields (2Z) and optimized grease lubrication allows the bearing to achieve a high limiting speed of 50,000 rpm, making it suitable for high-speed applications.
- Enhanced Sealing & Longevity: The non-contact shields protect the internal components from contaminants, and the pre-applied grease ensures smooth operation from the start. This design offers a maintenance-free solution, reducing downtime and total cost of ownership.
- Precision & Stability: Manufactured to P0 tolerance class with a standard CN radial clearance, it guarantees consistent performance and smooth running, which is critical for precision mechanisms.
