The thrust ball bearing is a single-row component that supports predominantly axial loads in one direction, with separable shaft and housing washers. It is used where the load pushes in the shaft direction and speeds are moderate, such as transmission columns, rotary tables and lifting mechanisms. At MR Accesorios Industriales we supply the FAG line with the full designation so that the quote is precise.

The designation of this family reads as a series of five digits starting with 511 followed by the size: 51100, 51101, 51102, 51103, 51104, 51105, 51106 and 51107 are the smallest steps of the series. The final number indicates the size of the assembly, not a standalone measurement. When the code includes suffixes, it is best to read them with the manufacturer's product page: they change design details, not the concept of the product.

In Argentine industry these thrust bearings appear in presses, screw lifts, cutting tables, milling heads and material handling equipment. They are also found in gearboxes and machine tools where the load is thrust and there is no relevant radial component. In those assemblies, the bearing works supported on flat surfaces and requires that the housing and shaft be well seated.

To select, start from the axial load the assembly will support and the direction of that load: the single-row thrust ball bearing takes thrust in one direction. Check the permissible rotational speed, because these bearings are not intended for high speeds. During installation, take care with the perpendicularity of the support faces and the alignment between shaft and housing; a tilted face concentrates the load on a few balls. Lubrication must reach the raceway and be renewed according to the duty cycle.

Between brands, interchangeability is resolved by designation and mounting dimensions: a thrust bearing of the 511 series from another manufacturer with the same code usually shares diameters and height. Still, before replacing, compare the suffix and the design, because two bearings with the same number may differ in cage or treatment. If in doubt, send us the original code and the code of the equipment where it is mounted.

If you need a FAG thrust ball bearing for equipment in operation, send the code via WhatsApp to MR Accesorios Industriales. With the full designation and, if possible, a photo of the assembly, we will quote promptly and guide you on the correct variant.
