SKF LUJR series linear units are ready-to-mount guidance components that pair a linear bearing with a machined housing. They provide smooth, repeatable travel for automation equipment, manipulators, and positioning systems where precision matters. MR Industrial Accessories supplies this line as part of its linear motion range.
The LUJR code identifies the product family and the nominal shaft or guide size. For example, LUJR 16, LUJR 20, LUJR 30, and LUJR 40 are different sizes within the same series. The number is not the outside diameter or overall length; it is a size reference that matches the appropriate shaft. Exact tolerances and dimensions for each size come from the corresponding data sheet.
These units appear in applications that require controlled linear movement: automation, machine tools, packaging equipment, material handling, and internal transport systems. They are also used in laboratory devices, test benches, and medical equipment that need smooth travel with minimal play. In production lines where fine adjustment and low maintenance are important, rigidity and repeatability are key.
When selecting a LUJR unit, consider the load it will carry, the travel speed, and the working environment. Sealing is critical if dust, chips, or moisture are present; confirm that the component includes adequate protection. Use the lubrication recommended by the manufacturer and renew it according to use. Proper alignment between the guide and housing prevents lateral forces that reduce service life. Mount with the correct fit and without forcing parts to ensure precise, long-lasting operation.
SKF linear units can be interchanged with products from other brands that follow the same standardized dimensions. Do not rely on the number alone: always verify mounting dimensions, load capacity, and type of sealing. MR Industrial Accessories supplies SKF and can guide you on compatible alternatives within its catalog.

Frequently asked questions
- What does the number in LUJR 20 mean?
- The number indicates the nominal size of the unit, which relates to the shaft or guide on which it is mounted. It is not the outside diameter or length. For exact dimensions of each size, check the data sheet or send the full part number via WhatsApp.
- How do I know if a LUJR unit is compatible with my machine?
- Verify the mounting dimensions, load capacity, and type of sealing. The LUJR series comes in several sizes, each with specific dimensions. Send the original unit's part number or the dimensions of your guide so we can advise you correctly.
- What lubrication do SKF linear units need?
- The right lubrication depends on the application and working conditions. Generally, use the grease or oil recommended by the manufacturer and follow the maintenance interval. To avoid risking the component's service life, check the manual or contact us for guidance based on your equipment.
