The SKF LUHR series covers linear units that pair a linear bearing with a machined housing, supplied ready to mount on cylindrical shafts. They turn rotary motion into precise linear displacement with low friction and can take loads from different directions. MR Industrial Accessories LLC supplies them as part of its linear motion line for customers across the United States, Canada, Mexico and South America.

Reading the designation helps you order the right unit. LUHR identifies the category of linear units with a cast iron or steel housing, and the number that follows is the nominal shaft diameter in millimeters. The LS suffix means the bearing carries double-lip seals at both ends, which aids lubricant retention and shields against contaminants. So LUHR 12-2LS is a unit for a 12 mm shaft with double sealing, and LUHR 50-2LS is for a 50 mm shaft. Several sizes are available to match different load capacities.

Typical use is where linear motion must be precise and repetitive: machine tools, automation equipment, manipulators, presses, measuring devices and internal transport systems. The food and pharmaceutical sectors also use them, since cleanliness and corrosion resistance matter there. Their compact design fits into tight spaces and simplifies mounting on existing structures.

Selection depends on the radial and axial load the unit will carry, the travel speed and the working environment. LS sealing suits surroundings with moderate dust or humidity; where liquids or fine particles are present, consider additional protection. The shaft should be ground and of suitable hardness, and alignment between housings must be careful to avoid parasitic stresses. Use the lubricant specified by the manufacturer and renew it according to use.

SKF linear units can be interchanged with products from other brands built to the same standardized dimensions, but tolerances and load capacity must be checked before replacing. Suffixes do not carry the same meaning from one maker to another, so it is safer to work from shaft dimensions and service conditions. Our team can help you find the unit that fits your application.
