The FR series deep groove ball bearing is a bearing with a flanged outer ring, designed for assemblies where axial location is handled by the flange itself instead of covers, lock nuts or housing shoulders. It is used in compact equipment with low to medium demands: small motors, fans, pumps, power tools and light transmission mechanisms. MR Accesorios Industriales sells this NSK series in Buenos Aires, Argentina.

The FR series designation is read in parts. The letters FR identify the family of deep groove ball bearings with a flange on the outer ring. The number that follows, as in FR 4B or FR 168B, corresponds to the bearing size within the series. The suffix B indicates an execution variant of the same size, usually linked to the type of closure or a modification of the contour. To request a quote, send the complete part number exactly as it appears on the drawing or on the part.

In Argentine industry, these bearings appear in equipment where axial space is limited and simple fixing of the outer ring is needed: small electric motors, centrifugal and axial fans, low-power water pumps, portable tools, office machines and appliance mechanisms. They are also found in laboratory equipment, instrumentation and light automation, where the flange simplifies the housing design and reduces the number of fastening parts.

To select and mount an FR series bearing, take into account the housing diameter and the flange position: the flange rests on a machined face and is fixed with screws or a shoulder. Check the internal clearance and the alignment between supports, because a poorly seated flange generates parasitic axial loads. Lubrication can be grease or oil depending on the equipment; in applications with dust or moisture, choose the execution with suitable sealing. Mounting is done with a press or puller, never by striking the flange.

Cross-references between brands are handled by dimensions and by flange type, not by the commercial part number. If the original bearing is from another brand, compare bore diameter, outer diameter, width, flange diameter and position, and type of closure. With that data, at MR Accesorios Industriales we indicate the compatible alternative. If the part has no identification, send us the measurements and a photo via WhatsApp and we'll quote it.

To move forward with your order, write to us via WhatsApp with the complete bearing part number, for example FR 4B or FR 168B, or with the housing measurements. At MR Accesorios Industriales we quote shortly. If you need several units or a variant of the FR series, we also handle it with the same part number.
