61902-2RS1 Bearing Product Overview & Core Advantages
The 61902-2RS1 is a miniature deep groove ball bearing designed for compact, high-precision applications requiring reliable performance in limited spaces. As a metric sealed bearing, its primary advantage lies in its ability to handle radial loads efficiently while offering protection against contamination. Manufactured with Chrome Steel rings and balls, it ensures durability and consistent operation. The bearing features a P6 tolerance class for enhanced running accuracy, making it suitable for applications demanding high rotational precision and reliability.
61902-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61902 | Basic model number denoting a deep groove ball bearing series with 15mm bore, 28mm OD, and 7mm width. |
| 2RS1 | Indicates contact seals on both sides, providing effective protection against contaminants and retaining lubricant. |
61902-2RS1 Bearing Structural Features & Performance Benefits
Optimized Sealed Design: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants, significantly extending bearing service life in harsh environments. This design also retains the factory-applied grease lubrication, supporting a maintenance-free operation.
High Precision & Rigidity: Built to a P6 tolerance class, this bearing offers superior dimensional accuracy and running precision. The single row deep groove construction, combined with a stainless steel cage, provides stable operation and high rigidity, essential for applications with precise rotational requirements.
Robust Load Capacity & Speed Performance: With a radial dynamic load rating of 980 lbf and a limiting speed of 16,000 rpm, the bearing is engineered to handle significant radial loads at high rotational speeds. The optimized internal geometry and quality materials contribute to its reliable performance under demanding conditions.
61902-2RS1 Bearing Typical Application Areas
- Small Electric Motors: Ideal for use in compact motors, fans, and blowers requiring reliable, high-speed operation.
- Precision Instruments: Suitable for medical devices, optical equipment, and measuring instruments where space is limited and accuracy is critical.
- Office Automation Equipment: Commonly used in printers, scanners, and copiers for precise shaft support.
- Robotics and Automation: Applied in small robotic joints, actuators, and conveyor systems demanding compact, high-precision bearings.
