The NSK F series is a single row deep groove ball bearing whose outer ring carries a flange, so it can be fastened straight onto a flat surface with a screw or pin instead of a fully machined housing. That makes it a practical choice where room is tight and assembly should stay simple, as in small pulleys, fans, appliances and instrumentation equipment. MR Industrial Accessories LLC supplies this series to customers throughout the United States and in several Latin American countries.

Reading the designation is straightforward: the letter F comes first and is followed by a three-digit number that identifies the size. Examples include F 602, F 603, F 604, F 605, F 606, F 607 and F 608, each a flanged outer ring bearing with its own dimensions. The digits are not a direct diameter reading; they place the bearing within the series. Send us the part number and we will confirm the exact dimensions for that reference.

Typical uses are those that call for compact, low-complexity mounting: small fans, low-power electric motors, water pumps, office machines, refrigeration equipment and household appliances. Automotive components such as tensioners and pulleys also use them, as do instrumentation and control devices.

Selection comes down to load type, rotation speed and the conditions where the bearing runs. Because the flange accepts a screw, the housing design can be kept simple. In dusty or damp locations, a sealed version is worth considering. Grease from the factory normally covers the service life, though more demanding duty may call for relubrication. Aligning shaft and housing correctly helps prevent extra loads.

Interchange is possible with other brands using the same nomenclature, such as SKF, FAG, NTN or KOYO, provided the dimensions and flange type line up. Give us the part number from your current brand and we will identify the equivalent, or quote the exact size you need.
