FAG Deep Groove Ball Bearings
Product Description
The 688-2Z FAG miniature deep groove ball bearing consists of an inner ring, an outer ring, balls, a cage, and two metal shields. Its compact design provides low friction, smooth operation, and high-speed performance while supporting radial and bidirectional axial loads. The metal shields help retain lubricant and protect the bearing against dust and contaminants.
The 688-2Z bearing is widely used in small electric motors, precision instruments, office equipment, miniature drives, and automation equipment. It is particularly suitable for compact applications requiring high-speed operation, low friction, low noise, and reliable contamination protection.
