6003-2RSHTN9/C3GJN Bearing Product Overview & Core Advantages
The 6003-2RSHTN9/C3GJN is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. Engineered to primarily handle radial loads, its compact design offers a robust solution where space is limited. A key advantage is its sealed construction, which provides superior protection against contaminants and retains lubrication, ensuring long service life and reduced maintenance needs. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers consistent performance for general precision applications.
6003-2RSHTN9/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6003 | Basic Bearing Series & Size | Indicates a metric, single row deep groove ball bearing with a 17mm bore, 35mm OD, and 10mm width. |
| 2RS | Contact Seals on Both Sides | Provides effective sealing against dust, moisture, and other contaminants from both sides. |
| HTN9 | Nylon Cage (Polyamide) | The lightweight cage contributes to low friction, quieter operation, and is suitable for higher speeds. |
| C3 | Greater than Normal Radial Internal Clearance | Allows for thermal expansion, making it suitable for applications with higher operational temperatures or where fits cause a reduction in clearance. |
| GJN | Grease Filling | The bearing is pre-lubricated with a specific grease, making it ready for immediate use without initial lubrication. |
6003-2RSHTN9/C3GJN Bearing Structural Features & Performance Benefits
Robust Construction for Radial Load Capacity: The single row deep groove raceway and high-quality chrome steel components are optimized to carry significant radial dynamic loads (1349 lbf) and radial static loads (731 lbf).
Sealed and Lubricated for Longevity: The combination of 2RS contact seals and factory-applied GJN grease creates a maintenance-free system. This sealed design effectively excludes contaminants and retains lubricant, significantly extending bearing service life in dirty or humid environments.
High-Speed Capability with Nylon Cage: The standard HTN9 nylon cage is lightweight, which reduces centrifugal forces and allows for a high limiting speed of 21,000 rpm. This contributes to lower operating temperatures and energy efficiency.
Thermal Stability with C3 Clearance: The C3 radial internal clearance provides operational stability across a wide temperature range (-30°C to 120°C), accommodating thermal expansion without risk of binding.
6003-2RSHTN9/C3GJN Bearing Typical Application Areas
This versatile and reliable bearing is commonly specified in:
- Electric Motors: Ideal for small to medium-sized motors requiring sealed, pre-lubricated units.
- Industrial Gearboxes: Used in various gearbox stages for supporting shafts under radial loads.
- Pumps and Compressors: Provides durable performance in fluid handling equipment.
- Material Handling Equipment: Conveyor rollers, pulleys, and other machinery components.
- Agricultural Machinery: Suitable for applications exposed to dust and moisture.
- General Machinery and Appliances: A go-to solution for a wide range of automated and consumer devices.
