6305-2Z/GJN Bearing Product Overview & Core Advantages
The 6305-2Z is a single row deep groove ball bearing featuring integral shielded protection on both sides. Engineered for radial load applications, this metric bearing offers reliable performance in a compact design. Its key advantages include simplified installation due to the non-contact shields, which help retain pre-applied lubricant and exclude contaminants without significantly increasing friction. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent operation for general industrial applications requiring dependable performance and moderate speed capability.
6305-2Z/GJN Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| 2Z | Steel shields on both sides | Provides effective contamination protection while maintaining low operating torque |
| GJN | Light pre-lubrication with lithium soap base grease | Offers initial running-in protection and extends service intervals |
6305-2Z/GJN Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The continuous raceway design enables the bearing to handle not only radial loads but also moderate axial loads in both directions, making it versatile for various mounting configurations.
Shielded Protection: The non-contact steel shields provide effective protection against particulate contamination while minimizing friction torque, contributing to the bearing's limiting speed of 11,000 rpm.
Material Construction: Manufactured entirely from chrome steel for rings, balls, and cage, ensuring consistent thermal expansion characteristics and reliable performance across the operating temperature range of -30°C to 120°C.
Standardized Quality: Built to ABEC 1 | ISO P0 tolerance class with CN radial internal clearance, providing predictable performance and interchangeability for industrial applications.
6305-2Z/GJN Bearing Typical Application Areas
- Electric Motors: Ideal for small to medium-sized industrial motors requiring shielded protection
- Material Handling Equipment: Conveyor systems, pulley assemblies, and gearboxes
- Industrial Fans & Blowers: Applications demanding continuous operation at moderate speeds
- Agricultural Machinery: Implement drives and auxiliary systems where contamination resistance is critical
- General Machinery: Pumps, compressors, and transmission systems in various industrial sectors
