6313 MC/P52 Bearing Product Overview & Core Advantages
The 6313 MC/P52 is a high-precision single row deep groove ball bearing designed for demanding applications requiring exceptional running accuracy and dimensional stability. Manufactured to ABEC 5 | ISO P5 tolerance standards, this bearing delivers superior performance in high-speed and high-rigidity scenarios. Its open design, combined with a machined metal cage, ensures reliable operation under significant radial loads and moderate axial loads. The bearing is supplied with a CN radial internal clearance, making it an ideal choice for precision spindles and machine tools where minimal runout and vibration are critical.
6313 MC/P52 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Advantage |
|---|---|---|
| MC | Machined Metal Cage | Provides high strength, excellent dimensional stability, and superior guidance for the balls, contributing to high-speed capability and reduced friction. |
| P52 | ISO P5 Tolerance Class & CN Clearance | Denotes a high-precision bearing with tight dimensional and running accuracy tolerances, paired with a standard CN radial internal clearance for optimal performance in most applications. |
6313 MC/P52 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The single row deep groove design, manufactured to ABEC 5/P5 standards, ensures extremely low noise and vibration levels, providing the necessary rigidity and running accuracy for precision machinery.
- Optimized Load Capacity: Engineered with a high dynamic and static radial load rating (2084 lbf / 13466 lbf), this bearing reliably supports substantial radial forces, making it suitable for heavy-duty operations.
