FAG deep groove ball bearings of the 619 series with the 2RZ suffix are thin-section components with two-sided sealing. They are used to guide shafts with moderate radial and axial loads in equipment where radial space is limited. MR Accesorios Industriales supplies this brand line for industrial and maintenance applications in Buenos Aires, Argentina.
The designation of this series reads as follows: the number 619 indicates a thin-section deep groove ball bearing series; the 2RZ suffix indicates that it comes with low-friction seals on both sides. In the examples 61909-2RZ, 61910-2RZ, 61911-2RZ, 61913-2RZ and 61914-2RZ, the last two digits before the suffix identify the bore size according to the code table. The 2RZ suffix does not change the outer dimensions: it only adds protection against contaminants and lubricant retention.
These bearings are chosen when a compact, sealed assembly is required. They appear in small electric motors, gearboxes, fans, centrifugal pumps, laboratory equipment and textile machinery. In Argentina they are found in packaging lines, compressed air transport and maintenance of rotating equipment where axial and radial space is limited. The 619 series is the thinnest section among deep groove ball bearings, which is why it is reserved for light loads and moderate to high speeds.
To select the correct bearing, take into account the shaft diameter, the type of load and the environmental conditions. The 2RZ sealing protects against dust and moisture, but it does not replace good lubrication: verify that the lubricant is compatible with the seal and with the operating temperature. During mounting, align the housings well and avoid impacts on the rings, because the thin section is more sensitive to deformation. If the equipment operates with vibration, check the internal clearance and the fit in the housing.
Regarding equivalents, deep groove ball bearings are identified by their numeric designation and sealing or clearance suffixes. Different manufacturers may use equivalent codes, but tolerances and internal clearance may vary. Therefore, when replacing a bearing, compare not only the code but also the seal type and the clearance class. If you have doubts, send us the complete code and the shaft and housing dimensions for advice.

Frequently Asked Questions
- What are the dimensions of the FAG 61910-2RZ bearing?
- The FAG 61910-2RZ bearing has a 50 mm bore, a 72 mm outside diameter and a 12 mm width (50 x 72 x 12 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 61910.
- What does the 2RZ suffix mean on a FAG bearing?
- The 2RZ suffix indicates that the bearing has low-friction seals on both sides. These seals protect against dust and moisture, and help retain the lubricant. They do not change the outer dimensions of the bearing.
- How do I choose the right 619 series bearing for my equipment?
- You need to know the shaft diameter, the type of load and the working conditions. The 619 series is thin-section, suitable for light loads. If you have the old code, send it to us along with the dimensions and we will help you select.
- Are FAG 619-2RZ series bearings interchangeable with other brands?
- Equivalents may exist in other brands, but check the seal type and the internal clearance, because they do not always match. The numeric designation helps, although tolerances may vary. Consult us with the code and dimensions to confirm interchangeability.
