The FR series deep groove ball bearing is a single row bearing with a flanged outer ring, designed for assemblies where the housing has no shoulder and simple axial location is needed. The flange allows the bearing to seat and center directly on the housing face, without machining a step. It is used in low and medium demand equipment, with mainly radial loads and moderate speeds. MR Accesorios Industriales sells the NSK FR series in Buenos Aires, Argentina.

The FR series designation reads as follows: the letters FR identify the family of deep groove ball bearings with a flange on the outer ring; the number that follows defines the size and dimensions of each variant. The ZZS suffix indicates sheet metal seals on both sides, with a small clearance that reduces the entry of dust and retains lubrication. In the examples FR 2-6 ZZS, FR 133 ZZS, FR 155 ZZS and FR 156 ZZS this structure is visible: series, size and sealing. If the part number has no suffix, the bearing is open.

These bearings appear in applications where axial space is limited and a mounting flange is needed: small electric motors, fans, centrifugal pumps, packaging machines, laboratory equipment and light-duty transmissions. In the Argentine market they are found in maintenance at food, textile and ceramics plants and in repair shops for household appliances and portable tools. The flange makes mounting easier in cast iron or folded sheet metal housings, where milling a step is not advisable.

To choose the right bearing, take into account the type of sealing: ZZS protects against dust and light humidity, but if there is water or fine particles, a rubber seal is preferable. Check that the flange matches the diameter and depth of the housing, and that the shaft has the recommended fit for the inner ring. When mounting, align the assembly well so as not to load the flange; lubricate with the grease indicated for the working speed and avoid blows to the seals. Careful alignment extends service life.

Flanged deep groove ball bearings are available under different nomenclatures depending on the manufacturer. When replacing a part, the safest approach is to compare the main dimensions: bore, outside diameter, width and flange diameter. If another brand's part number does not match, the equivalent can be found by those dimensions. At MR Accesorios Industriales we tell you the compatible alternative when you bring the part number or the exact size.
