6003-2Z/C3 GJN Bearing Product Overview & Core Advantages
The 6003-2Z/C3 GJN is a single row deep groove ball bearing designed for reliable performance in demanding applications. This shielded bearing offers robust radial load capacity and is pre-set with a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Its compact design and ABEC 1 precision ensure smooth operation and high reliability, providing a cost-effective solution for general industrial use.
6003-2Z/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6003 | Basic bearing series, indicating a metric deep groove ball bearing with 17mm bore, 35mm OD, and 10mm width. |
| 2Z | Bearing is equipped with non-contact shields on both sides, providing effective protection against contaminants while maintaining high-speed capability. |
| C3 | Specifies greater than normal radial internal clearance, ideal for applications with thermal gradients or where tight fits cause clearance reduction. |
| GJN | Indicates the use of a high-quality, heat-stabilized polyamide 66 cage (commonly referred to as GJN), offering excellent strength and guidance at high speeds. |
6003-2Z/C3 GJN Bearing Structural Features & Performance Benefits
Optimized Shield Design: The non-contact 2Z shields effectively prevent the ingress of contaminants while minimizing friction, allowing for a limiting speed of 21,000 rpm and extending bearing service life in dirty environments.
Enhanced Operating Clearance: The C3 radial clearance provides greater internal space than standard bearings, accommodating shaft expansion under operational heat or heavy loads, thereby preventing seizure and ensuring reliable performance.
High-Speed Cage: The polyamide 66 cage (GJN) is lightweight and offers superior guidance, reducing centrifugal forces and enabling smooth operation at high rotational speeds with minimal friction and noise.
Robust Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing delivers a dynamic load rating of 1349 lbf and a static load rating of 731 lbf, ensuring durability under significant radial stresses.
6003-2Z/C3 GJN Bearing Typical Application Areas
- Electric Motors and small motor applications requiring high-speed operation and contamination protection.
- Industrial Gearboxes and transmission systems where reliable radial load support is critical.
- Pumps and Compressors for handling radial loads in fluid and air movement equipment.
- Material Handling Equipment such as conveyors and rollers in manufacturing and logistics.
- Agricultural Machinery components exposed to harsh environments, benefiting from the shielded design.
- General Machinery and appliances where ABEC 1 precision and cost-effectiveness are key requirements.
