NTN 6000 ZZ C4 10x26x8 Deep Groove Ball Bearing

Reliable Performance for Industrial and Automotive Applications

The NTN 6000 ZZ C4 deep groove ball bearing is a precision-engineered component designed for high-speed rotation, durability, and consistent performance in demanding environments. With dimensions of 10 mm (inner diameter) x 26 mm (outer diameter) x 8 mm (width), this single-row ball bearing ensures smooth operation with minimal friction.

The ZZ designation indicates double metal shields that protect the internal components from dust, debris, and lubricant loss—extending service life while maintaining optimal lubrication. The C4 internal clearance allows the bearing to perform effectively in high-temperature or high-speed applications, where standard clearance bearings may experience thermal expansion.

This model is widely used in electric motors, pumps, gearboxes, conveyors, automation systems, and power tools, making it one of the most popular sizes in industrial and automotive engineering.

FAQ - Frequently Asked Questions

1. What does “C4” clearance mean in this bearing?
C4 clearance indicates a larger internal space between rolling elements and raceways. This design compensates for thermal expansion at higher operating temperatures and speeds.

2. What are the advantages of the “ZZ” shielded design?
The metal shields protect the bearing against dust and dirt while retaining factory-applied lubrication, making it virtually maintenance-free.

3. Is the NTN 6000 ZZ C4 suitable for electric motors?
Yes. Its low noise, precision finish, and high-speed capability make it ideal for electric motors and similar rotating machinery.

4. What is the difference between C3 and C4 clearances?
C4 bearings have more internal clearance than C3, allowing better heat dissipation and stability under higher loads or speeds.

5. How should this bearing be installed?
It should be mounted with clean tools and surfaces, ensuring proper alignment and avoiding excessive force on the shields.
