6203-2RSH/C3GJN7 Bearing Product Overview & Core Advantages
The 6203-2RSH/C3GJN is a sealed deep groove ball bearing designed for high reliability and robust performance in demanding applications. As a single row bearing, it excels at handling radial loads while also accommodating moderate axial loads in both directions. Its key advantages include extended service life due to effective sealing, operation across a wide temperature range, and compliance with major environmental regulations. The combination of a C3 radial internal clearance and high-quality chrome steel construction makes it a versatile and durable choice for a broad spectrum of industrial machinery.
6203-2RSH/C3GJN7 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Benefit |
|---|---|---|
| 6203 | Standard bearing series designation indicating metric dimensions: 17mm bore, 40mm OD, 12mm width. | Defines the core bearing dimensions for interchangeability and fit. |
| 2RS | Contact seals on both sides of the bearing. | Provides superior protection against contaminant ingress and retains lubricant, enhancing reliability. |
| H | Indicates the use of a specific, high-performance sealing material. | Improves seal durability and performance, especially in challenging environments. |
| /C3 | Radial internal clearance greater than normal (C3 clearance). | Ideal for applications with expected thermal expansion, such as in electric motors, ensuring stable operation. |
| GJN | Indicates the bearing is pre-lubricated with a specific, high-quality polyurea grease. | Offers excellent performance over a wide temperature range (-30°C to +120°C) and long-term lubrication, reducing maintenance needs. |
6203-2RSH/C3GJN7 Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from high-carbon chrome steel (rings, balls, and cage), this bearing ensures high strength, wear resistance, and consistent performance under load.
Enhanced Sealing & Contamination Resistance: The 2RSH contact seals are a critical feature, providing an effective barrier against dust, moisture, and other contaminants. This significantly extends the bearing's operational life in harsh or dirty environments and makes it a maintenance-free solution for many applications.
Optimized Internal Clearance & Thermal Stability: The C3 radial internal clearance is engineered to accommodate misalignments and thermal expansion encountered in applications like electric motors. This prevents preloading and potential seizure, ensuring smooth and reliable operation.
Ready-to-Use Lubrication: Pre-filled with GJN grease, the bearing is immediately operational upon installation. This grease maintains its stability and lubricity across the specified temperature range, contributing to a long service interval and reducing downtime.
6203-2RSH/C3GJN7 Bearing Typical Application Areas
The 6203-2RSH/C3GJN is a versatile component suited for a wide range of industrial sectors. Its sealed and pre-lubricated design makes it particularly valuable in applications where reliability and minimal maintenance are paramount.
- Electric Motors: A standard choice for various AC and DC motors, where the C3 clearance accommodates shaft expansion.
- Industrial Gearboxes and Transmissions: Used to support shafts and handle radial loads.
- Material Handling Equipment: Conveyor rollers, pulleys, and fans.
- Agricultural Machinery: Implements and equipment requiring protection from dust and moisture.
- General Industrial Machinery: Pumps, compressors, and other machinery requiring a reliable, sealed bearing solution.
