The SKF linear unit of the LUNF series is a guidance component that combines a linear bearing with a machined housing, ready to mount on fixed structures. It is used to move loads in a straight line with low friction in machine tools, automation equipment and handling systems. MR Accesorios Industriales supplies this line as an official brand, with technical advice to choose the right variant for the application.

The LUNF series designation is interpreted by its letters: the L indicates it is a linear unit, the U indicates the housing or mounting unit, the N corresponds to the standardized design and the F distinguishes the type of fixing or housing. The number that follows, as in the example LUNF 40, identifies the size or nominal diameter of the shaft on which it slides. Each size accepts different sealing and preload configurations, which are chosen according to the environment and the required precision.

These units are used in industries such as automotive, food, woodworking and metallurgy, in applications where repetitive and precise linear movement is needed. In Argentina they are commonly seen in cutting tables, internal conveyor systems, presses and testing equipment. They also appear in packaging machines and positioning devices that require rigidity and repeatability. Their compact format makes it easy to build linear axes with a minimum number of parts.

To select correctly, take into account the load it will support, the travel speed and the environmental conditions. Sealing is key if there is dust, chips or humidity: choose the appropriate protection to prevent contaminants from entering the bearing. Lubrication must be the one specified by the manufacturer and renewed according to use. Alignment of the shaft and housing prevents lateral forces and extends service life. Assembly with correct fit reduces vibration and noise.

SKF linear units can be interchanged with equivalent products from other brands, but there is no universal standardization of dimensions or capacities. Therefore, before replacing a unit, compare the mounting dimensions, shaft height, fixing type and load capacity. In many cases it can be replaced by another brand while maintaining performance, but always verify compatibility with the existing shaft and housing. MR Accesorios Industriales can help you with that comparison.
