FAG deep groove ball bearings of the 2Z series are single-row ball components with two metal shields, designed to withstand moderate radial and axial loads in both directions. They are used in electric motors, fans, pumps, gearboxes and transmission equipment. MR Accesorios Industriales sells this line, with technical advice to select the correct part number for your application.

The designation of these bearings combines a basic three-digit number that indicates the size and the dimension series, followed by the 2Z suffix. For example, in 608-2Z the 608 defines the bore, outside diameter and width according to the standard, while 2Z indicates that the bearing has two metal shields, one on each side. Other part numbers in the same family, such as 6000-2Z or 6200-2Z, share that logic: the number identifies the size and the suffix the sealing or clearance variants.

In Argentine industry, these bearings appear in low and medium power electric motors, centrifugal fans, centrifugal pumps, conveyor belts, machine tools and packaging equipment. They are also found in automotive applications, such as alternators and tensioners. Their closed construction with metal shields makes them suitable for environments with moderate dust or dirt, where the aim is to retain the lubricant without the hermetic sealing of a rubber seal.

To select the correct part number, take into account the shaft diameter, the expected radial and axial loads, and the rotational speed. The 60, 62 and 63 series differ in section and load capacity. The 2Z suffix indicates metal protection; if the environment has humidity or fine particles, a rubber seal (2RS) may be preferable. Check the alignment of the shaft and the housing, and lubricate according to the application. Mounting must be done with suitable tools, without striking directly on the balls.

Deep groove ball bearings are manufactured under international dimension standards, so an equivalent part number from another brand can usually be interchanged dimensionally. However, tolerances, internal clearance and the type of lubricant may vary between manufacturers. If you need to replace an existing bearing, the safest approach is to compare the complete part number and the service conditions. At MR Accesorios Industriales we can guide you on interchangeability.

If you already have the part number of the bearing you need, write to us on WhatsApp and we will quote it shortly. We can also advise you if you are assembling new equipment or if the original bearing has no visible identification. MR Accesorios Industriales sells FAG bearings, along with a broad line of transmission and mounting components.
