61840 Bearing Product Overview & Core Advantages
The 61840 metric ball bearing is a single row deep groove ball bearing engineered for high-performance applications requiring precise radial load support. Characterized by its open design and manufactured to a P6 tolerance class, this bearing delivers exceptional running accuracy and rotational stability. Its robust construction, featuring chrome steel rings and balls with a stainless steel cage, ensures high reliability and a long service life. This bearing is ideal for applications demanding high rotational speeds and consistent performance under significant radial dynamic loads.
61840 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61840 | Standard metric series designation for a single row deep groove ball bearing with a 200mm bore. |
| Open (No Seal/Shield) | The bearing is supplied without seals or shields, allowing for optimal heat dissipation and the possibility for application-specific lubrication systems. This configuration is suited for clean environments or where high speeds are critical. |
| P6 Tolerance | Indicates a precision tolerance class tighter than standard, resulting in superior running accuracy, reduced vibration, and controlled internal clearance. |
| CN Clearance | Specifies the standard (normal) range for radial internal clearance, suitable for a wide range of general operating conditions. |
61840 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to a P6 tolerance class with precisely controlled dimensions, this bearing provides high rotational accuracy and rigidity, minimizing deflection under load.
- Optimized for High Speeds: The combination of an open design, a lightweight stainless steel cage, and high-quality chrome steel components enables a high limiting speed of 3,200 rpm, making it an excellent high-speed bearing.
- Superior Load Capacity: With a high radial dynamic load rating of 17,108 lbf and a radial static load rating of 22,931 lbf, it is built to handle significant radial forces in demanding applications.
- Robust Material Construction: The use of chrome steel for rings and balls provides high hardness and wear resistance, while the stainless steel cage offers excellent corrosion resistance and strength.
- Flexible Lubrication: Supplied without grease (lubrication: none), allowing the end-user to select the optimal lubricant for their specific speed, temperature, and environmental conditions.
61840 Bearing Typical Application Areas
This precision bearing is suited for a variety of industrial machinery and equipment where high speed and radial load capacity are paramount. Common applications include:
- Electric Motors and Generators
- Industrial Gearboxes
- Pumps and Compressors
- Machine Tool Spindles and other precision machinery
