6302-2Z/C3HT Bearing Product Overview & Core Advantages
The 6302-2Z/C3 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This shielded bearing offers reliable radial load capacity and moderate axial loads in both directions. Its key advantages include robust construction for high rigidity, a C3 radial internal clearance suitable for applications with thermal expansion, and pre-lubrication for immediate operation. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a cost-effective solution for high reliability and long service life in various industrial settings.
6302-2Z/C3HT Bearing Model Code Explained, Specifications & Naming Convention
The model number 6302-2Z/C3 breaks down as follows:
- 6302: Basic series number, indicating a medium-duty, metric deep groove ball bearing with a 15mm bore and 42mm outside diameter.
- 2Z: Designates double-shielded construction (one shield on each side). This provides effective protection against contaminants while retaining lubricant, making it suitable for maintenance-free or minimal-maintenance operation.
- C3: Indicates a greater radial internal clearance than the standard CN group. This is advantageous in applications where thermal expansion of the shaft or housing is expected, preventing excessive preload and potential bearing failure.
6302-2Z/C3HT Bearing Structural Features & Performance Benefits
- Robust Single Row Design: The deep groove raceway and high-quality chrome steel construction (rings, balls, and cage) deliver excellent high rigidity and durability under radial dynamic loads up to 2563 lbf.
- Optimized Load Handling: While primarily for radial loads, the deep groove geometry also accommodates moderate axial loads from both directions, offering versatility in application design.
- Shielded & Pre-Lubricated: The 2Z shields effectively seal the bearing, protecting it from dust and debris. The bearing comes pre-lubricated, ensuring immediate startup and smooth operation, contributing to a long, maintenance-free service life.
- Enhanced Operational Range: The C3 clearance allows for stable operation across a wide temperature range (-30°C to 120°C) and in conditions where fit or thermal effects are a concern, preventing binding and reducing friction.
6302-2Z/C3HT Bearing Typical Application Areas
This versatile bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
