WBB1-8708 R-2RS1 Bearing Product Overview & Core Advantages
The WBB1-8708 R-2RS1 is a single row deep groove ball bearing designed for compact applications requiring reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its sealed design (2RS1) with pre-lubricated grease, providing protection against contaminants and enabling long-term, maintenance-free operation. This bearing is engineered to handle primarily radial loads efficiently within a constrained space, making it a robust and durable solution for precision instruments and small mechanisms.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| WBB1-8708 | Manufacturer's specific series and size code. Indicates a metric bearing with an 8 mm bore, 14 mm outside diameter, and 4 mm width. |
| R | Designates a bearing with a flanged outer ring. The flange (Ø15.6 mm) facilitates secure axial location and simplifies mounting. |
| 2RS1 | Signifies contact seals on both sides. The RS1 type seals provide effective protection against dust and moisture, retaining lubricant for extended service life. |
WBB1-8708 R-2RS1 Bearing Structural Features & Performance Benefits
- Compact & Robust Flange Design: The integrated flange on the outer ring ensures easy and precise installation, preventing axial movement and enhancing system stability in compact assemblies.
- Superior Corrosion Resistance: Manufactured from stainless steel for rings, balls, and cage, this bearing is ideal for applications exposed to moisture, chemicals, or demanding environments, ensuring long-term reliability.
- Effective Sealing & Lubrication: The 2RS1 double seals effectively shield the internal components from contaminants. Pre-greased from the factory, the bearing offers ready-to-use, maintenance-free operation throughout its service life.
- Precision & Load Capacity: Built to P0 tolerance class and standard CN radial internal clearance, it provides consistent running accuracy. It is rated for a dynamic load of 104 lbf and a static load of 43 lbf, suitable for light to moderate radial loads.
WBB1-8708 R-2RS1 Bearing Typical Application Areas
- Small Electric Motors (e.g., in drones, precision tools)
- Medical and Dental Equipment
- Office Automation Equipment (printers, scanners)
- Precision Instruments and Optical Devices
- Food Processing Machinery (due to stainless steel construction)
- Robotics and Small Gearboxes
