6040 M Bearing Product Overview & Core Advantages
The 6040 M is a high-precision single row deep groove ball bearing engineered for demanding applications requiring exceptional radial load capacity and rotational accuracy. Characterized by its open design and manufactured to a P6 tolerance class, this bearing is ideal for high-speed operation and scenarios where precise shaft guidance is critical. Its robust construction from chrome steel components ensures high durability and reliable performance under substantial radial loads, making it a superior choice for industrial machinery.
6040 M Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Benefit |
|---|---|---|
| M | Machined Brass Cage | Provides high strength, excellent dimensional stability, and superior performance at high speeds and temperatures. |
| P6 | Tolerance Class | Offers tighter dimensional and running accuracy than standard bearings, reducing vibration and noise for precision applications. |
| CN | Normal Radial Internal Clearance | Standard clearance suitable for most common operating conditions and bearing fits. |
6040 M Bearing Structural Features & Performance Benefits
- High Load Capacity: The optimized raceway geometry and use of high-grade chrome steel enable a high dynamic load rating of 48,559 lbf and a static load rating of 55,078 lbf, ensuring reliable operation under significant radial stresses.
- High-Speed Capability: The combination of the machined brass cage (M) and the P6 precision class allows for a high limiting speed of 3,600 rpm, minimizing friction and heat generation.
- Precision & Rigidity: Manufactured to a P6 tolerance class, this bearing guarantees precise running accuracy and contributes to the overall system rigidity, which is crucial for minimizing deflection in high-precision spindles and shafts.
- Versatile Operating Range: With a temperature range from -30°C to 120°C and an open design, it is suitable for a wide array of industrial environments, though it requires an appropriate external sealing and lubrication system.
6040 M Bearing Typical Application Areas
The 6040 M is ideally suited for applications that demand high precision, speed, and radial load capacity. Key industries and equipment include:
- Electric Motor Shafts
- Industrial Gearboxes
- Machine Tool Spindles
- Pumps and Compressors
