6203-2Z/C3GJN Bearing Product Overview & Core Advantages
The 6203-2Z/C3GJN is a metric single row deep groove ball bearing designed for reliable performance in demanding applications. Its core advantages stem from its shielded design (2Z) and C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. This bearing excels at handling radial loads and offers robust operation within a wide temperature range. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a cost-effective solution for general industrial use where precision and contamination protection are key requirements.
6203-2Z/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
The model number 6203-2Z/C3GJN is decoded as follows:
- 6203: Standard designation for a single row deep groove ball bearing with a 17 mm bore, 40 mm OD, and 12 mm width.
- 2Z: Indicates the bearing is shielded on both sides. These non-contact steel shields protect the internal components from large particulate contamination while minimizing friction.
- C3: Specifies a greater than normal radial internal clearance. This is beneficial for applications involving thermal expansion, heavy interference fits, or where operational heat generation is expected.
- GJN: Signifies the use of a specific polyurea-thickened grease with a consistent temperature performance and good mechanical stability.
6203-2Z/C3GJN Bearing Structural Features & Performance Benefits
- Robust Shielding: The double-shielded (2Z) construction effectively retains the factory-applied grease and excludes larger contaminants, enhancing bearing life in dirty environments without the added torque of contact seals.
- Optimized Internal Clearance: The C3 clearance provides operational stability in applications prone to thermal expansion or where shaft and housing fits result in a reduction of internal clearance, preventing premature failure due to overheating or binding.
- High-Quality Materials: Constructed entirely from chrome steel (GCr15) for rings, balls, and cage, ensuring high strength, durability, and consistent performance under the specified dynamic and static load ratings.
- Pre-Greased for Longevity: The bearing is pre-lubricated with GJN grease, offering reliable performance across the specified temperature range (-30°C to 120°C) and is suitable for the limiting speed of 17,000 rpm, making it a ready-to-install, maintenance-free component for many applications.
6203-2Z/C3GJN Bearing Typical Application Areas
This versatile bearing is commonly found in:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
