6305-2Z Bearing Product Overview & Core Advantages
The 6305-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This shielded bearing offers a robust solution for primarily radial loads, featuring a metric design with a 25 mm bore. Its key advantages include high operational reliability, low maintenance requirements due to its pre-lubricated and shielded construction, and excellent running accuracy supported by its P6 tolerance class. It is an ideal choice for applications requiring a compact, durable, and ready-to-install precision bearing.
6305-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 63 | Series designation indicating a medium width and a specific internal design optimized for load capacity. |
| 05 | Bore diameter code representing a 25 mm bore. |
| 2Z | Signifies non-contact shields on both sides. This provides effective protection against contamination while minimizing friction, contributing to the high limiting speed. |
6305-2Z Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 5261 lbf and a radial static load rating of 2608 lbf, ensuring stable performance under significant stress.
- Enhanced Durability & Speed: The stainless steel cage ensures dimensional stability and reduced wear at high speeds, supporting a limiting speed of 13,000 rpm. The optimized internal geometry minimizes friction and heat generation.
- Maintenance-Free Operation: The 2Z shields effectively retain the factory-applied grease lubrication and exclude contaminants. This creates a sealed-for-life unit, reducing maintenance costs and downtime.
- Precision Performance: Manufactured to a P6 tolerance class with a standard CN radial internal clearance, this bearing guarantees precise running and smooth operation, which is critical for applications with high accuracy requirements.
6305-2Z Bearing Typical Application Areas
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., Conveyors)
- Agricultural Machinery
- General Industrial Machinery requiring reliable radial support
