626-2Z/C3GJN Bearing Product Overview & Core Advantages
The 626-2Z/C3GJN is a single row deep groove ball bearing designed for high reliability and robust performance in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering a compact design. The combination of shielded construction and a C3 radial internal clearance makes it suitable for applications requiring operational stability under varying thermal conditions. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent precision and is an excellent choice for general industrial use where cost-effectiveness and dependable performance are paramount.
Model Code Breakdown
- 626: Basic series designation for a single row deep groove ball bearing with a 6mm bore.
- 2Z: Indicates the bearing is shielded on both sides. This provides effective protection against contamination while allowing for high-speed operation.
- C3: Denotes a greater than normal radial internal clearance. This is beneficial for applications with significant thermal expansion or where interference fits are used.
- GJN: Signifies the use of a specific, high-quality grease lubricant, ensuring optimal performance and longevity right from installation.
626-2Z/C3GJN Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from chrome steel, including rings, balls, and cage, ensuring high strength and durability for consistent performance under radial dynamic loads up to 447 lbf.
Contamination Protection: The non-contact shields (2Z) effectively retain the factory-applied grease and protect the internal components from dust and other particulates, enhancing service life without significantly impacting the limiting speed of 32,000 rpm.
Thermal & Fit Adaptability: The C3 clearance accommodates thermal expansion and interference fits, preventing premature failure due to excessive preload, making it a versatile choice for a wide temperature range of -30°C to 120°C.
Pre- Lubricated for Immediate Use: The bearing is pre-lubricated with GJN grease, making it ready for immediate installation and operation, which simplifies maintenance and reduces downtime.
626-2Z/C3GJN Bearing Typical Application Areas
