6301-2Z/C3GJN Bearing Product Overview & Core Advantages
The 6301-2Z/C3GJN is a single row deep groove ball bearing designed for reliable performance in demanding applications. This shielded bearing features a C3 radial internal clearance, making it particularly suitable for applications where thermal expansion is a concern. Its robust construction from chrome steel ensures durability and consistent operation, while the integral shields provide effective contamination protection without significantly impacting speed capability. This combination delivers a robust solution for radial load applications requiring long service life and minimal maintenance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6301 | Basic bearing series, indicating a medium duty, single row deep groove ball bearing with a 12mm bore. |
| -2Z | Bearing is equipped with non-contact shields on both sides. This provides excellent protection against contaminants while allowing for high rotational speeds. |
| /C3 | Specifies a greater than normal radial internal clearance. This is ideal for applications with expected thermal expansion or where interference fits are used. |
| GJN | Indicates the bearing is supplied without lubrication (None). This allows the user to apply a specific lubricant tailored to their application's requirements. |
6301-2Z/C3GJN Bearing Structural Features & Performance Benefits
- Optimized for Radial Loads: The single row deep groove raceway geometry is precision-engineered to efficiently support significant radial dynamic load ratings (2181 lbf).
- Enhanced Operational Stability: The C3 clearance provides operational tolerance for thermal expansion, reducing the risk of preload and associated friction and heat generation, thereby contributing to stable performance.
- Effective Contamination Protection: The non-contact ZZ shields act as a physical barrier against dust and debris, significantly extending bearing life in unclean environments without the high torque associated with contact seals.
- High-Speed Capability: The combination of a chrome steel cage, precision ABEC 1 (ISO P0) tolerances, and low-friction shields enables a high limiting speed of 20,000 rpm.
- Material Integrity: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing offers high hardness, wear resistance, and a long operational lifespan under standard conditions.
6301-2Z/C3GJN Bearing Typical Application Areas
