6313-2Z/C3GJN Bearing Product Overview & Core Advantages
The 6313-2Z/C3GJN is a single row deep groove ball bearing engineered for robust performance in demanding applications. Its core advantage lies in its ability to efficiently handle radial loads while offering operational reliability. Featuring integrated shields (2Z) and a C3 radial internal clearance, this bearing is pre-configured for applications with thermal expansion or heavy loads, ensuring stable operation and extended service life. Its ABEC 1 (ISO P0) tolerance provides consistent quality for a wide range of industrial uses.
6313-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6313 | Basic designation for a single row deep groove ball bearing with a 65mm bore and 140mm OD. | Standardized dimensions for easy interchangeability. |
| 2Z | Bearing is equipped with shields on both sides. | Provides effective protection against contaminants, retaining pre-applied grease. |
| C3 | Specifies a greater than normal radial internal clearance. | Accommodates thermal expansion in applications with high speeds or heavy loads, preventing premature failure. |
| GJN | Indicates the bearing is lubricated with a Polyurea-based grease. | Offers excellent performance over a wide temperature range (-30°C to +120°C) and contributes to long-term, maintenance-free operation. |
6313-2Z/C3GJN Bearing Structural Features & Performance Benefits
Robust Construction for High Load Capacity: Manufactured from high-grade chrome steel for both rings, balls, and cage, the 6313-2Z/C3GJN is built for durability. This homogeneous material selection ensures consistent thermal expansion and high dynamic and static load ratings (2084 lbf / 13466 lbf).
Optimized for Challenging Conditions: The C3 clearance is a critical feature, allowing the bearing to perform reliably in applications where shaft and housing fits or operational temperatures cause preload, preventing seizure and reducing friction.
Sealed and Lubricated for Life: The combination of double shields (2Z) and high-performance Polyurea grease (GJN) creates a sealed, maintenance-free unit. This design effectively excludes contaminants and retains lubrication, making it ideal for applications where re-lubrication is difficult or impossible.
Balanced High-Speed Performance: The deep groove raceway and precision-ground components contribute to smooth operation and a high limiting speed of 4,800 rpm, suitable for a variety of motor and drive applications.
6313-2Z/C3GJN Bearing Typical Application Areas
The 6313-2Z/C3GJN is a versatile component suited for numerous industrial sectors requiring reliable rotational motion and radial load support. Key applications include:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Fans
