Description
NSK RA30AN belongs to linear guide, part of our Linear motion range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for RA30AN and any equivalents.
The NSK RA series linear guide consists of a rail and a ball-recirculating carriage. It is designed to move loads with low friction and high repeatability, making it suitable for axes, gantries, and tables that require smooth, precise travel. MR Industrial Accessories supplies this guide and provides quotes through WhatsApp based on the model you specify.
The model code for the RA series includes a size number and a suffix. In models such as RA15AN, RA20AN, RA25AN, RA30AN, RA35AN, RA45AN, RA55AN, and RA65AN, the number denotes the guide size, while the AN suffix indicates the carriage variant and its configuration. A larger number corresponds to a larger guide section and higher load capacity. To ensure a correct match, always provide the complete code from the drawing or the part being replaced.
Typical applications for these guides include machining centers, measuring machines, automation equipment, manipulators, and general translation axes. They are found in metalworking shops, food plants, packaging lines, and machinery factories. In operations with frequent motion cycles, the linear guide helps maintain precision and reduce wear compared to other sliding systems.
When selecting an RA series guide, consider the load per carriage, rail length, mounting rigidity, and the sealing type required for the environment. Proper alignment between parallel rails is critical; any difference in height or parallelism will accelerate wear. Use the lubricant specified for linear guides and renew it according to usage. In dusty, chip-prone, or humid conditions, additional protection is recommended.
Linear guides can sometimes be interchanged between brands by size number and carriage configuration, but mounting dimensions and height may not always match. If you have a guide from another brand or an unidentified part, provide the code or measurements and we can suggest a compatible equivalent. MR Industrial Accessories supplies NSK and other brands and can help you find a replacement that works for your machine.
To request a quote for your NSK RA series linear guide, send the full model, such as RA25AN, and the quantity needed via WhatsApp. If you have a drawing or a photo of the part, that will help us confirm the variant. We respond promptly with the quote and a suitable alternative for your equipment.

Frequently asked questions
- How can I identify the model of my NSK linear guide?
- Check for the code engraved on the carriage or rail. The RA series uses a size number and the AN suffix, like RA20AN or RA35AN. If you cannot locate it, send a photo and the main measurements via WhatsApp, and we will assist you.
- What does the AN suffix indicate in the RA series?
- The AN suffix specifies the carriage variant and its configuration within the RA series. It does not affect the guide size, which is determined by the number. To verify the correct variant, provide the full code from your equipment.
- Is it possible to replace a guide from another brand with an NSK RA series guide?
- In many cases, yes, but you must compare height, width, hole spacing, and load capacity. The nominal size alone is not sufficient. Send us the original guide code or measurements, and we will indicate a compatible equivalent.
