Linear guideways (or linear rails) are essential components in most CNC machines, 3D printers, and motion system DIY projects. This article outlines the steps and explains how to order the right linear guideway and its accessories.

1. Product Brands:
   Currently, we offer two types of linear guideways on our website: HIWIN and Non-HIWIN (Compatible, Generic). HIWIN products and their accessories are typically regarded as high-quality, precision components, often used in motion systems requiring high reliability and accuracy. Non-HIWIN (compatible) products are more popular with DIY users due to their relatively lower price and decent quality. If you're a first-time buyer or new to DIY projects, Non-HIWIN products might be a better choice, as their models, sizes, and specifications are identical to HIWIN’s.
2. Sliding Block (Bearing Block):
   The sliding block (bearing block) is often considered a consumable part, especially the non-HIWIN bearing blocks. If it’s used in a high-frequency motion system, we recommend considering a design that allows for easy replacement. If there are no budget concerns, obviously, the HIWIN brand of bearing blocks is the recommended choice.
3. Product Bundling:
   For all of our linear guideway products (except bundle items), the guide rail and bearing block are sold separately, regardless of the product image. This gives customers more flexibility to choose whether or not to include the bearing blocks or simply replace them.
4. Customizable Length:
   The length of the linear guideway is customizable. We list and price it per centimeter. Simply input the desired length (in cm) in the quantity box when adding to your shopping cart. Please refer Custom Length: https://diycnc.ca/?p=11894
