The ZARF is a super precision thrust bearing from the FAG line, designed for machine tool spindles, rotary tables and positioning mechanisms where angular accuracy and axial rigidity are critical. It combines a needle roller thrust bearing with a radial ball bearing in a compact assembly, which allows it to absorb axial loads in both directions and simultaneous radial loads. MR Accesorios Industriales supplies this line as an official FAG brand.

The ZARF designation is read in blocks: the letters identify the family of super precision thrust bearings with an integrated radial component, and the number that follows summarizes the main dimensions of the assembly. The -L suffix indicates a particular lubrication or sealing configuration within the series, while -TV refers to the type of cage or retaining element used. In the examples ZARF1560-L-TV, ZARF1762-L-TV or ZARF3080-L-TV, the first two digits of the numeric block relate to the shaft diameter and the following ones to a characteristic mounting dimension. To interpret a specific code, it is best to consult the manufacturer's dimension table.

These bearings are chosen for applications where position control is decisive: main spindles of milling machines, grinding machines and machining centers, precision rotary tables, measuring heads and robot axes. In Argentine industry they appear in the metalworking, automotive, aeronautical and machine tool sectors, both in new equipment and in spindle repairs that demand high repeatability and rigidity. They are also used in indexing devices and in assemblies where axial space is limited.

To select the right bearing, consider the axial load in both directions, the simultaneous radial load, the rotational speed and the required mounting precision. Sealing and lubrication are critical: these assemblies usually work with high-quality oil or grease lubrication, and the cage type influences the thermal regime. The alignment between shaft and housing must be very tight, with mounting tolerances compatible with the bearing's precision class. Misaligned mounting or incorrect preload reduces service life and affects accuracy.

As for equivalents, super precision thrust bearings with a similar function are offered under different nomenclatures depending on the manufacturer, but they are not interchangeable without verifying dimensions, tolerances and load capacity. The ZARF designation is specific to FAG, and replacing it with another brand requires comparing the complete assembly: diameters, height, cage type and lubrication conditions. MR Accesorios Industriales supplies FAG as an official brand, and can advise on the right variant within the series.

If you need to identify a ZARF bearing or get the replacement for your equipment, send the complete part number on WhatsApp to MR Accesorios Industriales. With the model and working conditions, the technical team can confirm the variant and give you a quote promptly.
