61822 Bearing Product Overview & Core Advantages
The 61822 metric ball bearing is a single row deep groove ball bearing engineered for high-precision radial load applications. Manufactured to a P6 tolerance class, it delivers exceptional running accuracy and dimensional stability. Its open design facilitates high-speed operation, with a limiting speed of 5,600 rpm, making it an ideal precision bearing for demanding machinery. The use of high-grade chrome steel for rings and balls ensures durability and a long service life under rigorous operating conditions.
61822 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61822 | Standard designation for a single row deep groove ball bearing with a 110mm bore and 140mm outside diameter. |
| Open | No seals or shields, allowing for higher speeds and easier re-lubrication but requiring a clean operating environment. |
| P6 | Indicates a tolerance class with tighter dimensional and running accuracy than standard (P0) bearings. |
| CN | Specifies the standard (normal) radial internal clearance group. |
61822 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The single row deep groove construction, combined with a P6 tolerance and a rigid stainless steel cage, provides excellent rotational accuracy and stability, minimizing vibration and runout.
- Radial Load Capacity: Optimized for high radial dynamic load ratings (6317 lbf), this bearing is designed to handle significant radial forces efficiently.
- High-Speed Capability: The open design and precision-ground components contribute to a high limiting speed of 5,600 rpm, qualifying it as a capable high-speed bearing.
- Material Integrity: Constructed from chrome steel for both rings and balls, it offers high hardness, wear resistance, and a consistent performance across its operating temperature range of -30°C to 120°C.
61822 Bearing Typical Application Areas
This high-precision, open ball bearing is suited for applications requiring accurate rotation and high speeds in clean environments. Common uses include:
- Precision spindles and motor shafts
- Industrial gearboxes and pumps
- Machine tool components
- Medical and laboratory equipment
- Agricultural machinery
