KOYO R series deep groove ball bearings are single-row ball components designed to support moderate radial and axial loads in both directions. They are used in electric motors, pumps, fans, gearboxes and industrial transmissions. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, with more than 80 years of experience in the field. Request a quote for the code you need via WhatsApp.
The R series designation is read with the size number and the R suffix. For example, 6004R, 6204R, 6205R, 6206R, 6207R, 6210R, 6303R and 6304R: the first two digits indicate the diameter series (60, 62 or 63) and the following ones the size. The final R identifies an execution with construction features specific to KOYO. To select, take into account the bore, outer and width dimensions shown in the designation.
These bearings are used in electric motors, centrifugal pumps, fans, compressors, conveyor belts and machine tools. In the Argentine industrial sector they are common in food, textile, chemical and material processing plants. Their sealed or shield-protected design allows them to be used in environments with moderate dust or moisture. The KOYO R series is a reliable option for equipment that operates continuously.
To choose correctly, consider the sealing type: open, with shields (2RZ) or with seals (2RS). Internal clearance and lubrication must be suitable for the operating speed and temperature. During mounting, ensure alignment between shaft and housing, and avoid impacts that damage the raceways. Correct lubrication and precise fitting extend bearing service life.
When replacing a bearing, you may find cross-references between brands: SKF, FAG, NSK, NTN and others often share the same dimensions for similar designations. If you have another brand's code, send it and we will indicate the equivalent KOYO reference. We can also help you if the part has no visible identification.
