The deep groove ball bearing is the most common type of bearing. It supports radial and axial loads in both directions and performs well at high speeds. The NSK AZZ series includes compact models with metal shields on both sides, ideal for equipment requiring protection against particles and low friction. It is used in electric motors, fans, pumps, portable tools and precision machinery. At MR Accesorios Industriales we quote the exact part number you need.

The AZZ series designation reads as follows: the first number indicates the size, and the AZZ suffix indicates that the bearing has two metal shields (ZZ) and a riveted steel cage (A). For example, 684 AZZ1, 686 AZZ1 and 688 AZZ1 are compact sizes from the 68 series, with small outside diameters. The final 1 may indicate a cage or tolerance variant. Learn more about this nomenclature by checking each part number.

These bearings are used in low-power electric motors, fans, centrifugal pumps, power tools, precision instruments and medical equipment. In Argentina, you will find them in the automotive industry, home appliances, textile machines and automation equipment. Their small size makes them suitable for confined spaces where high speed and low noise are required.

To select the correct bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. The AZZ metal shield protects against dust and moderate moisture, but it is not suitable for immersion. Check shaft and housing alignment, and lubricate with quality grease. Proper fit during mounting prevents deformation and extends service life.

NSK AZZ series bearings are interchangeable with those from other brands that follow the same international nomenclature. If you have another brand's part number, we can identify the equivalent. Always verify the critical dimensions: bore, outside diameter and width. Interchangeability is not always direct; contact us with the original part number and we will advise you.
