6307-2Z/VA201 Bearing Product Overview & Core Advantages
The 6307-2Z/VA201 is a single row deep groove ball bearing engineered for exceptional reliability in demanding applications. This shielded bearing excels at handling radial loads and moderate axial loads in both directions. Its key advantages include a robust construction for high rigidity, extended service life due to solid lubricant, and suitability for a wide temperature range from -30°C to 350°C, making it a versatile and durable solution for high-reliability scenarios.
6307-2Z/VA201 Bearing Model Code Explained, Specifications & Naming Convention
- 6307: Standard designation for a single row deep groove ball bearing with a 35mm bore and 80mm outside diameter.
- 2Z: Indicates the bearing is shielded on both sides. This provides effective protection against contamination while allowing for higher speeds compared to contact seals.
- VA201: Signifies the use of a solid lubricant. This is critical for operation in extreme temperatures, vacuum environments, or where liquid lubricants are unsuitable, ensuring consistent performance and long-term, maintenance-free operation.
6307-2Z/VA201 Bearing Structural Features & Performance Benefits
Robust Construction & High Load Capacity: Manufactured from chrome steel for both rings, balls, and cage, this bearing offers high strength and durability. It features a CN radial internal clearance and ABEC 1 (ISO P0) tolerance class, providing a balance of precision and robustness for a wide range of industrial applications. The design delivers a high radial dynamic load rating of 7509 lbf and a static load rating of 4339 lbf.
High-Temperature & Maintenance-Free Performance: The integration of solid lubricant (VA201) is the cornerstone of its performance. It enables reliable operation across a vast temperature range of -30° to 350°C, eliminating the risk of lubricant degradation, drying, or leakage. Combined with non-contact shields (2Z), this creates a sealed, pre-lubricated unit that requires no maintenance throughout its service life.
Optimized for Stable Operation: The limiting speed of 8,500 rpm is supported by the low-friction solid lubricant and the effective shielding that retains the lubricant and excludes contaminants, contributing to smooth and stable running.
6307-2Z/VA201 Bearing Typical Application Areas
The 6307-2Z/VA201 is ideally suited for applications requiring reliability in harsh conditions. Key industries and equipment include:
- High-Temperature Ovens & Furnaces: Conveyor systems and fan units.
- Food Processing & Packaging Machinery: Where lubrication contamination must be avoided.
- Electrical Motors & Generators: Especially in high-temperature or sealed environments.
- Textile Machinery: Dryers and finishing equipment exposed to heat.
- Vacuum Pumps and Cleanroom Equipment: Where outgassing from conventional lubricants is a concern.
