Superprecision thrust bearings in the FAG ZKLF line are double-acting assemblies built with precision washers. They handle axial loads together with radial loads where rotational accuracy matters most, which is why machine tool spindles, rotary tables, measuring heads and positioning systems rely on them. MR Industrial Accessories LLC supplies this series and helps you match size and sealing to the job.

Reading the code tells you most of what you need. In a designation such as ZKLF1255-2Z-XL or ZKLF3080-2Z-XL, the leading digits give the bore and the digits that follow give the outside diameter. The -2Z marking means there are protective seals on both faces, while -XL points to the manufacturer's current catalogue design. Longer numbers such as ZKLF3590-2Z-XL and ZKLF30100-2Z-XL confirm how far the size range extends. Ordering is simple when you send the full part number.

Where do these units earn their place? Spindles on milling, grinding and machining centre equipment, rotary tables on measuring machines, lathe heads, and automation that needs accurate angular positioning. Die-making shops, precision machining plants, metrology labs and machine tool builders also put them to work. Indexing devices and robot axes that see combined axial and radial load with high rigidity are another common home.

Selection comes down to the axial and radial load the bearing will see, the speed it will run at, and the precision level required. The -2Z seals keep dust and chips out; in the presence of coolant or moisture, it pays to review lubrication and mounting together with the matching precision washers. Shaft-to-housing alignment cannot be neglected, since any deviation shortens service life. Tightening and lubrication should follow the manufacturer's instructions.

Interchange is possible with equivalent products from other brands that share the same design and dimensions. Diameter alone is not enough: sealing type, precision class and load capacity all have to line up. Replacing an existing bearing? Send the part number engraved on the unit or its main dimensions and we will help identify a suitable equivalent among the brands we supply.
