6309 M Bearing Product Overview & Core Advantages
The 6309 M is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered to primarily handle radial loads, it features a P6 tolerance class for high precision and a robust construction using chrome steel rings and balls. Its optimized internal geometry and stainless steel cage contribute to smooth operation and high limiting speed, making it a reliable choice for high-performance machinery requiring accuracy and durability.
6309 M Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| M | Machined Brass Cage | Provides superior strength, stability, and guidance at high speeds compared to stamped cages. |
| P6 | Tolerance Class | Tighter dimensional and running accuracy than standard (P0) bearings, ensuring precise shaft positioning. |
| CN | Normal Radial Internal Clearance | Standard clearance suitable for most common operating conditions and fits. |
6309 M Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The P6 tolerance class and precise manufacturing ensure minimal runout and high dimensional stability, which is critical for applications requiring accurate rotational motion.
- Optimized Load Capacity: The deep groove raceway and high-quality chrome steel construction enable a high dynamic load rating of 12,432 lbf, providing reliable performance under significant radial loads.
- Enhanced High-Speed Capability: The machined brass (M) cage offers excellent strength and guidance for the balls, reducing friction and wear, which directly supports the high limiting speed of 14,000 rpm.
- Durability and Corrosion Resistance: The stainless steel cage provides good resistance to corrosion, enhancing the bearing's lifespan in challenging environments.
