61852 Bearing Product Overview & Core Advantages
The 61852 metric ball bearing is a high-precision, single row deep groove ball bearing engineered for demanding applications. Its primary function is to support substantial radial loads with high operational reliability. Manufactured to a P6 tolerance class, this bearing offers superior dimensional accuracy and running precision, making it an ideal choice for high-performance machinery where rotational accuracy is paramount. The open design allows for versatile lubrication options, while the robust construction ensures long service life and consistent performance under the specified operating conditions.
61852 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61852 | Standard designation for a metric series, single row deep groove ball bearing. |
| Open | No seals or shields, allowing for high-speed operation and custom lubrication regimes. |
| 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. |
61852 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The single row design with a P6 tolerance class ensures excellent running accuracy and dimensional stability, critical for applications requiring minimal vibration and precise shaft positioning.
- Radial Load Capacity: Engineered with a dynamic load rating of 24,954 lbf and a static load rating of 36,644 lbf, this bearing is built to handle significant radial forces reliably.
- High-Speed Capability: The stainless steel cage and open construction contribute to a high limiting speed of 2,400 rpm, making it suitable for rapid rotation applications.
- Material Durability: Components made from chrome steel (rings and balls) offer high hardness and wear resistance, while the stainless steel cage provides excellent corrosion resistance and strength.
- Versatile Application Range: The open seal type and standard CN clearance allow for flexible lubrication and accommodate a wide operating temperature range from -30°C to 120°C.
61852 Bearing Typical Application Areas
This high-precision ball bearing is ideally suited for applications requiring robust performance and accuracy, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment
- Precision Machine Tool Spindles
- Pumps and Compressors
