1---Determine the rail width. Rail width refers to the width of the slide rail. Track gauge is one of the key factors determining the load-carrying capacity. 2---Determine the rail length. This length is the total length of the rail, not the stroke. Total length = Effective stroke + Slider spacing (for two or more sliders) + Slider length × Number of sliders + Safety strokes at both ends. If guards are installed, the compressed length of the guards at each end must also be added. It is important to confirm in advance the maximum full length of the guide rail for this brand and specification. If the required length exceeds this limit, the rails will need to be joined together. Most manufacturers produce full-length tracks with a maximum length of 4,000mm (while micro-tracks typically come in 1,000mm lengths); some also offer 3,000mm options. This varies depending on the manufacturer’s machining equipment. Interface drawings should be provided when integration is required and the customer wishes to pre-machise mounting holes on the equipment. Another point to note: the hole spacing on the rail is fixed. When determining the rail length, users should pay attention to the positioning. For example, a No. 15 rail with a length of 600 mm. If you do not specify the required end dimensions to the supplier, the standard delivery condition is typically 10 mounting holes, with the distance from each end face of the rail to the nearest mounting hole center being 30mm on both ends. However, other dimensions may also be available. Shipping specifications for end dimensions vary slightly among brands; in most cases, both ends are assumed to be equal by default. One more point: regarding the length tolerance of the linear guide rails, most brands typically specify ±1–2mm for lengths under 2,000 mm, and ±2–3mm for lengths between 2,000 and 4,000 mm. 3—Determine the slider type and quantity. The two most common types of sliders are flange-type and square-type. The former is slightly lower but wider; its mounting holes are through threaded holes. The latter is taller and narrower; its mounting holes are tapped blind holes. Both types are available in short, standard, and extended lengths. The primary difference lies in the length of the slider body (the metal component). Additionally, the hole spacing of the mounting holes may vary; most short-length sliders have only two mounting holes. The number of sliders should be determined by the user through calculation. For now, we recommend adhering to this guideline: use just enough to ensure load-bearing capacity, and no more than what can be practically installed. The type and number of sliders, together with the rail width, constitute the three key factors that determine the load capacity.
