6205-2Z/GJNVQ086 Bearing Product Overview & Core Advantages
The 6205-2Z is a single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its core advantage lies in its ability to efficiently handle radial loads while offering a compact and cost-effective solution. The inclusion of integral shields (2Z) provides effective protection against contaminant ingress, enhancing operational lifespan. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing ensures consistent performance and is an excellent choice for applications requiring a balance of precision, durability, and value.
Model Code Breakdown
The model number 6205-2Z is decoded as follows:
- 6205: Standard designation for a single row deep groove ball bearing with a 25 mm bore diameter.
- 2Z: Signifies that the bearing is equipped with shields on both sides. These non-contact metal shields retain lubrication and protect the internal components from large particulate contaminants.
- GJNVQ086: This is typically a manufacturer-specific internal code, which may refer to a particular lot, packaging, or a special process not defined in public standards. For technical specifications, the primary focus remains on the 6205-2Z base model.
6205-2Z/GJNVQ086 Bearing Structural Features & Performance Benefits
- Robust Construction: Built entirely from chrome steel for the rings, balls, and cage, this bearing offers high strength and resistance to wear, contributing to a long service life under standard operating conditions.
- Effective Contamination Protection: The double-shielded (2Z) design is a key feature, offering superior protection compared to open bearings. It helps to retain the initial grease (if lubricated post-installation) and excludes larger contaminants, making it suitable for environments where dust and debris are present.
- High-Speed Capability: With a limiting speed of 13,000 rpm, this bearing is capable of operating in high-speed applications such as electric motors and fans.
- Precision & Reliability: Manufactured to ABEC 1 precision class, it provides reliable running accuracy and smooth operation, which is essential for reducing vibration and noise in machinery.
