FAG deep groove ball bearings in the 2Z series are single-row units fitted with a metal shield on each side. They handle moderate radial and axial loads in both directions and are common in electric motors, fans, pumps, gearboxes and transmission equipment. MR Industrial Accessories supplies this line and can help you match the right part number to your application.

Reading the code is straightforward. A three-digit basic number defines the size and dimension series; the 2Z suffix tells you both sides carry metal shields. In 608-2Z, for instance, 608 sets bore, outside diameter and width to the standard, while 2Z confirms the shielding. The same pattern applies across 6000-2Z, 6200-2Z and other numbers in the family: the digits give the size, the suffix gives sealing or clearance variations.

These bearings show up in low and medium power electric motors, centrifugal fans and pumps, conveyor belts, machine tools and packaging equipment. Automotive uses include alternators and tensioners. Because the metal shields are not hermetic, the bearing suits moderately dusty or dirty surroundings where the goal is to keep lubricant in without the tightness of a rubber seal.

When choosing a part number, check shaft diameter, expected radial and axial loads, and rotational speed. The 60, 62 and 63 series differ in section height and load capacity. The 2Z suffix means metal protection; for humidity or fine particles, a rubber-sealed 2RS may be the better fit. Confirm shaft and housing alignment, lubricate to suit the application, and use proper tools during mounting so the balls are never struck directly.

Deep groove ball bearings are made to international dimension standards, so an equivalent part number from another brand often interchanges dimensionally. Tolerances, internal clearance and lubricant type can still differ from one maker to another. For a replacement, compare the full part number and the service conditions. MR Industrial Accessories can advise on interchangeability.

If you already know the bearing part number, send it on WhatsApp or by email and the team will reply promptly with a quote. They can also help when you are building new equipment or when the original bearing has no readable identification. MR Industrial Accessories supplies FAG bearings alongside a broad range of transmission and mounting components.
