61803-2RS1 Bearing Product Overview & Core Advantages
The 61803-2RS1 is a single row deep groove ball bearing designed for compact, high-precision applications. Its primary advantage lies in its ability to efficiently handle radial loads while offering a sealed, maintenance-free solution. The metric dimensions (17mm bore, 26mm OD, 5mm width) make it ideal for space-constrained assemblies. Manufactured with chrome steel rings and balls, and a stainless steel cage, it delivers reliable performance and long service life, particularly in applications demanding high rotational accuracy and operational reliability.
61803-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61803 | Basic series designation for a single row deep groove ball bearing with a 17mm bore. |
| 2RS1 | Indicates the bearing is fitted with contact seals on both sides. The RS1 seal type provides effective protection against contamination and retains lubricant, making the bearing suitable for dirty environments. |
61803-2RS1 Bearing Structural Features & Performance Benefits
- Robust Sealing: The 2RS1 double-contact seals effectively shield the internal components from dust, moisture, and other contaminants, while securely retaining the factory-applied grease lubrication. This results in a maintenance-free bearing with enhanced operational longevity.
- High Precision & Speed: Built to P6 tolerance class and featuring a lightweight stainless steel cage, this bearing ensures smooth operation and is capable of achieving a limiting speed of 16,000 rpm, making it suitable for high-speed applications.
- Radial Load Capacity: The deep groove raceway and optimized internal geometry provide a dynamic load rating of 456 lbf and a static load rating of 286 lbf, offering reliable performance under significant radial stresses.
- Standard Internal Clearance & Material Quality: With a CN radial internal clearance and components made from high-grade chrome steel, the bearing ensures consistent performance, low noise, and vibration across a wide temperature range of -30°C to 120°C.
61803-2RS1 Bearing Typical Application Areas
This sealed deep groove ball bearing is widely used in various compact and precision-driven industries, including:
- Small Electric Motors (e.g., cooling fans, servo motors)
- Office Automation Equipment (e.g., printers, scanners)
- Medical Devices and Dental Handpieces
- Precision Instruments and Optical Encoders
- Food Processing Machinery (where sealed units are advantageous)
