The NSK R ZZ series deep groove ball bearing is a single-row bearing with metal shields on both sides, designed to handle moderate radial and axial loads in both directions. It is used in equipment that requires low maintenance and protection against dust and dirt. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and quotes it by WhatsApp with the exact part number.
The R ZZ series designation reads as follows: the letter R identifies NSK's Inch Series, with inch dimensions; the number that follows indicates the bearing size within that series. The ZZ suffix corresponds to two metal shields that protect the inside of the bearing. For example, R 6 ZZ is a bearing from the R series with metal shields on both sides. Each part number has specific dimensions that we provide when quoting.
These bearings are used in industries such as food, textile, packaging and precision machinery, where spaces are tight and loads are not high. In Argentina you find them in small electric motors, fans, pumps, conveyors and laboratory equipment. Their metal shields make them suitable for environments with dust or particles, though not for immersion.
To select the correct bearing, take into account the shaft diameter, radial and axial loads, and rotation speed. The ZZ shield is non-contacting, which allows higher speeds than a rubber seal, but with lower lubricant retention. During mounting, check shaft and housing alignment, and avoid striking the shields. Lubrication comes from the factory; if you need to relubricate, ask us.
NSK R ZZ series bearings can be interchanged with those of other brands that follow the same Inch series nomenclature, such as the 1600 or 6000 series in inches. Always verify the critical dimensions: bore, outer diameter and width. If you have another brand's part number, we can tell you the compatible equivalent. MR Accesorios Industriales advises you so the part works without issues.
