6301-ZTN9/C3MT33 Bearing Product Overview & Core Advantages
The 6301-ZTN9/C3MT33 is a single row deep groove ball bearing engineered for high-performance applications requiring precision and reliability. Its design excels at handling significant radial loads while also accommodating moderate axial loads in both directions. This bearing features a shielded design and is pre-lubricated with high-performance grease, making it a robust and long-lasting solution for demanding industrial environments. The combination of a nylon cage and C3 radial internal clearance contributes to its suitability for applications with thermal expansion considerations and higher operational speeds.
Model Code In-Depth Explanation
| Code Segment | Technical Meaning |
|---|---|
| 6301 | Basic bearing series, indicating a metric single row deep groove ball bearing with a 12mm bore, 37mm OD, and 12mm width. |
| Z | One side shielded. The shield protects against contamination while offering low friction. |
| TN9 | Polyamide (Nylon) cage, snap-type design. This cage material allows for quieter operation, lower friction, and is suitable for higher speeds. |
| C3 | Radial internal clearance greater than Normal (C0). This is selected for applications where fits or operational temperatures may cause a reduction in internal clearance. |
| MT33 | The bearing is factory-filled with a specific high-quality lithium soap base grease. This lubrication provides effective performance across the specified temperature range. |
6301-ZTN9/C3MT33 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and robust construction enable high radial dynamic load rating (2181 lbf) and radial static load rating (944 lbf), ensuring dependable performance under significant stress.
- High-Speed Capability: The lightweight nylon cage (TN9) minimizes centrifugal forces and friction, contributing to a high limiting speed of 20,000 rpm. The C3 clearance also accommodates thermal expansion at elevated speeds.
- Enhanced Service Life & Reliability: The shield (Z) effectively retains grease and excludes larger contaminants. Combined with the pre-applied MT33 grease, this design offers long-term, maintenance-free operation in many applications.
- Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing provides consistent running accuracy for general precision applications.
