SMF83 2rs Bearing Product Overview & Core Advantages
The SMF83 2RS is a miniature sealed ball bearing designed for precision applications requiring compact dimensions and reliable performance. This single row deep groove ball bearing features integral rubber seals (2RS) on both sides, providing excellent protection against contaminants and retaining lubrication. Constructed entirely from stainless steel (rings, balls, and cage), it offers superior corrosion resistance. Its core advantages include the ability to handle radial loads efficiently, compact 3x8x3 mm design for space-constrained assemblies, and long service life due to its sealed and pre-lubricated construction, making it ideal for high-reliability, miniature applications.
SMF83 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| SMF83 | Standard bearing designation indicating a metric, flanged, miniature bearing with a 3mm bore, 8mm OD, and 3mm width. | Defines the compact bearing dimensions and the presence of a mounting flange. |
| 2RS | Contact rubber seals on both sides of the bearing. | Provides superior sealed protection against dust and moisture, retains lubricant for extended life. |
SMF83 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for handling radial loads and facilitating high-speed operation up to 54,000 rpm.
- Stainless Steel Construction: All critical components (rings, balls, cage) are made from stainless steel, providing excellent corrosion resistance and durability, suitable for harsh environments.
- Integrated Flange (9.2mm OD): The flange simplifies mounting and positioning, enhancing assembly accuracy and stability in housings.
- Double Rubber Contact Seals (2RS): These seals effectively exclude contaminants and retain the factory-applied lubricant, resulting in a maintenance-free and long-lasting bearing solution.
- ABEC1 Precision & MC3 Clearance: Offers a standard level of running accuracy and an internal clearance suitable for a wide range of operating conditions, ensuring smooth and reliable performance.
