Product Overview and Core Advantages
The 61844 metric ball bearing is a precision single row deep groove ball bearing engineered for demanding applications requiring high radial load capacity and exceptional running accuracy. Manufactured to P6 tolerance class, it delivers superior dimensional stability and rotational precision. Its open design facilitates high-speed operation, with a limiting speed of 2,800 rpm, making it an ideal choice for high-performance machinery where reliability and high rigidity are paramount.
61844 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61844 | Standard designation for a single row deep groove ball bearing with a 220mm bore and 270mm outside diameter. |
| Open | No seals or shields, allowing for higher speeds and easier relubrication access. |
| P6 | Indicates a tolerance class with tighter dimensional and running accuracy than standard (P0) bearings. |
| CN | Specifies the standard (normal) group of radial internal clearance. |
Structural Features and Performance Benefits
- High Load Capacity: The optimized raceway geometry and use of high-grade chrome steel for rings and balls provide a high radial dynamic load rating of 17,535 lbf and a radial static load rating of 24,729 lbf, ensuring durability under significant stress.
- Precision and Speed: The P6 tolerance ensures minimal runout and vibration, which is critical for high-speed applications up to 2,800 rpm. The stainless steel cage provides robust guidance for the balls, contributing to stable operation at high velocities.
- Robust Construction: The single row deep groove design is inherently simple and effective, offering a compact solution with high operational reliability. The specified dimensional tolerances guarantee a precise fit during installation.
- Versatile Temperature Range: With an operating temperature range from -30°C to 120°C, this bearing is suitable for a wide array of industrial environments.
