WBB1-8706-2RS1 Bearing Product Overview & Core Advantages
The WBB1-8706-2RS1 is a metric single row deep groove ball bearing designed for high reliability in compact applications. Its core advantages stem from its sealed construction and stainless steel components, making it suitable for environments requiring corrosion resistance. This bearing is engineered to handle primarily radial loads efficiently while offering a wide operating temperature range from -30°C to 120°C. Its pre-lubricated and sealed design ensures long-term performance with minimal maintenance, ideal for applications demanding precision and durability.
WBB1-8706-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| WBB1-8706 | Basic bearing designation indicating the specific bearing size with a 6mm bore, 12mm OD, and 4mm width. |
| 2RS1 | Denotes sealed bearing construction with two rubber contact seals (RS) on both sides, providing effective protection against contaminants. |
WBB1-8706-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 rubber contact seals effectively shield the internal components from dust, moisture, and other contaminants, significantly enhancing bearing life and reliability in harsh conditions. This contributes to its maintenance-free characteristics.
- Corrosion Resistance: Manufactured entirely from stainless steel (rings, balls, and cage), this bearing offers excellent resistance to corrosion, making it suitable for applications exposed to water, chemicals, or washdown environments.
- Precision & Load Capacity: Built to P0 tolerance class with a CN radial internal clearance, it ensures consistent performance and smooth operation. The design is optimized to handle the specified radial dynamic load rating of 91 lbf effectively.
- Optimized Lubrication: The bearing is pre-lubricated with grease, which is suitable for the specified temperature range and contributes to a limiting speed of 32,000 rpm, ensuring stable operation across its intended use cases.
WBB1-8706-2RS1 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a compact, corrosion-resistant, and sealed solution. Key industries and equipment include:
- Small electric motors and gearboxes
- Medical and dental equipment
- Food processing and packaging machinery
- Precision instruments and optical devices
- Office automation equipment (e.g., printers, scanners)
