The NSK NS AL series linear guide is a linear motion assembly made up of a rail and a ball-recirculating carriage. It is built to move loads with low friction and high repeatability, making it suitable for axes, gantries and tables that demand accurate guidance and rigidity. The AL version uses a wide carriage, which adds stability against moment loads. Quotes are based on the part number and size.

The NS series code is organized by size and carriage style. Take models such as NS15AL, NS20AL, NS25AL, NS30AL and NS35AL: the numeric portion gives the nominal guide size, while the trailing letters identify the carriage. The L stands for an extended carriage, and the A indicates a wider or higher-capacity version. When you request a quote, include the full part number exactly as shown on the drawing or machine label.

Typical installations include machining centers, laser cutting machines, measuring equipment, manipulators and plant automation. In machine tool maintenance, packaging lines and test benches, these guides often replace friction slides. If the environment contains dust, chips or coolant, add proper protection for both the rail and the carriage.

Selection depends on the load per carriage, the tilting moment, the stroke length and the rigidity of the assembly. For mounting, the support surface must be flat and aligned, and the rail should be seated and tightened progressively. Service life is influenced by lubrication with a suitable grease or oil and by carriage sealing. Also confirm preload and clearance according to the precision required by the axis.

Linear guides can be interchanged between manufacturers by size and carriage type, but mounting dimensions, height and hole patterns do not always match. If you have an unidentified guide or a part number from another brand, we can identify a compatible alternative. To do that, we need the part number, a photo of the component and the main dimensions of the rail and carriage.

To replace an NSK NS AL series linear guide, send the part number by WhatsApp. At MR Industrial Accessories we will quote the exact size your machine needs and reply promptly. You can also ask about lubricants and mounting accessories to get the axis running.
