Deep groove ball bearings are the most common bearing type, featuring two rings, a cage, and a row of balls that handle radial and axial loads in both directions. They are found in electric motors, pumps, fans, gearboxes, and machine tools. We supply the NTN line with metric sizes and light, medium, and extra-light series to match different speed and load needs.

The part number tells you the series and bore. The first two digits indicate the series: 60 for light, 62 for medium, 63 for heavier duty, and 68 and 69 for extra-light designs where space is tight. The last two digits give the bore diameter. For example, 6008, 6009, and 6010 are all in the 60 series but have different bores. Numbers with a slash, such as 68/500, 68/530, 68/560, and 68/600, denote large bore diameters in the extra-light series. Suffixes cover sealing, internal clearance, or cage type.

These bearings appear in many industrial settings: electric motors, centrifugal pumps, fans, compressors, conveyor belts, machine tools, and process equipment. They also suit low- and medium-power applications that need low friction and straightforward maintenance. Since they are used widely, they are common in both new equipment and replacement work, so the range of sizes and variants in the NTN line is broad.

When selecting, consider the sealing method: open, metal shielded, or rubber sealed, depending on whether the environment has dust, moisture, or splashes. Internal clearance and cage design also affect speed and operating temperature. During installation, pay attention to alignment between supports, cleanliness of the shaft and housing, and proper fit, because over-tightening or impact on the balls can shorten service life. Correct lubrication completes the job.

Interchangeability between brands relies on designation and dimensions: a bearing from the 60, 62, or 63 series can usually be replaced by an equivalent from another brand if bore, outer diameter, and width match. When the part number alone is not enough, compare dimensions and sealing type. If you have a part number from another brand or an unidentified part, send us the details and we will suggest a compatible alternative.
