SKF linear units of the LUHR series are guidance components that combine a linear bearing with a machined housing, ready to mount on cylindrical shafts. They are used to convert rotary motion into high-precision linear displacement, with low friction and the ability to support loads in different directions. At MR Accesorios Industriales we sell them as part of our linear motion line, with more than 80 years of experience in the field.

The LUHR series designation is interpreted as follows: the letters LUHR identify the category of linear units with a cast iron or steel housing, and the number that follows indicates the nominal shaft diameter in millimeters. The LS suffix indicates that the bearing incorporates double-lip seals at both ends, which improves lubricant retention and protection against contaminants. For example, LUHR 12-2LS corresponds to a unit for a 12 mm shaft with double sealing, while LUHR 50-2LS is for a 50 mm shaft. The series covers several sizes to adapt to different load capacities.

These units are used in applications requiring precise and repetitive linear motion. In Argentine industry we find them in machine tools, automation equipment, manipulators, presses, measuring devices and internal transport systems. They are also common in the food and pharmaceutical sector, where cleanliness and corrosion resistance are important. Their compact design allows them to be integrated into tight spaces and simplifies mounting on existing structures.

To correctly select a LUHR unit, you must consider the radial and axial load it will support, the travel speed and the environmental conditions. The LS sealing is suitable for environments with moderate dust or humidity; if there is exposure to liquids or fine particles, additional protections should be evaluated. Mounting requires that the shaft be ground and have the appropriate hardness, and that the alignment between the housings be careful to avoid parasitic stresses. Lubrication must be the one indicated by the manufacturer and renewed according to use.

Regarding equivalences, SKF linear units can be interchanged with products from other brands that follow the same standardized dimensions, but it is essential to verify tolerances and load capacity before replacing. Not all suffixes mean the same thing between manufacturers, so we recommend being guided by the shaft dimensions and service conditions. At MR Accesorios Industriales we can advise you to find the unit compatible with your application.
