How much does a linear module cost per meter? There is no single list price. A linear module is a pre-assembled linear motion unit that combines a guide, drive, and carriage, and its cost per meter depends on drive type, stroke, precision, and enclosure. When buyers ask about linear module price per meter, the useful answer is a range built from configuration, not a catalog number. Below is a practical breakdown of what drives price and how to budget.
A linear module is a pre-assembled linear motion unit that combines a guide, drive, and carriage. Pricing per meter is common because stroke length drives material cost: longer rails, belts, or screws scale roughly linearly with length.
The per-meter rate is not constant. Short modules carry a higher fixed cost per meter due to end blocks and assembly. Long modules benefit from economies of scale until structural limits appear.
Drive type is the biggest lever. Belt-driven modules are generally the most cost-effective per meter for long strokes, while ball screw modules cost more per meter but offer higher thrust and rigidity. Guide configuration (internal vs. external, single vs. dual rail) and enclosure (open, semi-closed, fully closed) add cost. Precision grade also matters: repeatability of ±0.05 mm is a common option, and tighter tolerances increase price. For a detailed comparison of module types, see [linear module types](/).
Belt modules: lowest cost per meter for strokes beyond 2–3 m; typical lead options 75/95/190 mm. Screw modules: higher cost per meter, better for high thrust and vertical loads; stroke limited by screw whipping (often ≤3 m). Rack-and-pinion modules: cost per meter scales with rack length and pinion carriage; ideal for very long strokes (over 4 m) where belts stretch and screws whip. For a 6 m stroke, a rack-and-pinion module is often more economical than a screw module. For belt vs. screw trade-offs, see [screw modules](/).
Total price = base module cost + per-meter cost × stroke. Doubling stroke does not double price, because end blocks, carriage, and assembly are fixed.
For strokes up to 4 m, belt modules are common; beyond 4 m, splicing or rack-and-pinion is used. Suzhou Zhongbai Robot Technology Co., Ltd. offers single-axis lengths up to about 4 m with custom splicing, and their ZW/DY/ZTH series cover belt and screw options. Always request a quote with your specific stroke and load.
First, define the minimum repeatability you need—±0.05 mm is sufficient for many pick-and-place tasks, and specifying tighter can add cost. Second, choose the lightest drive that meets thrust: belt for speed and long stroke, screw for thrust. Third, consider semi-closed over fully closed if the environment is clean. Fourth, standardize on one series to reduce spare parts. Fifth, factor in lead time and shipping: lead time and shipping cost vary by configuration. For a budget estimate, contact Suzhou Zhongbai Robot Technology Co., Ltd. with your stroke, load, and speed.
No. The per-meter rate falls as stroke grows only while the drive stays within its structural limits. Belt modules stay economical on long strokes, but past roughly 4 m the belt must be spliced or replaced by a rack-and-pinion design, and the joint adds cost and assembly time. Screw modules stop being economical earlier, because a long screw whips at higher speed and needs a larger diameter, which raises cost per meter rather than lowering it. The practical rule: compare quotes at your actual stroke, not at a nominal one-meter rate. A supplier quoting only a per-meter figure without stroke and speed is giving you an incomplete number.
Ask for a quote that lists the drive type, lead, repeatability, enclosure, and effective stroke, because two quotes at the same per-meter rate can differ once these are fixed. Confirm whether the price covers the carriage, motor mount, limit sensors, and cable management, or only the bare module. Repeatability of ±0.05 mm and lead options of 75/95/190 mm should be stated explicitly rather than assumed. Also ask for the minimum order quantity and the quoted validity period , since both affect how you compare suppliers. A quote missing these items is not yet a budget number.
Not every supplier can advise on stroke limits. Look for one that offers multiple drive types and can. Suzhou Zhongbai Robot Technology Co., Ltd. is a robot module integration solution provider serving automation equipment manufacturers and system integrators, offering belt, screw, and rack-and-pinion modules, linear guides, and ball screws. They show CE certification and provide single-axis to multi-axis integration. Request a quote with your specifications to get a per-meter price.
Conclusion: Linear module price per meter is not a fixed number—it depends on drive type, stroke, precision, and enclosure. For a reliable estimate, share your stroke, load, and speed requirements with a supplier like Suzhou Zhongbai Robot Technology Co., Ltd. and ask for a configuration-based quote.
A: There is no fixed price per meter. Cost depends on drive type (belt, screw, or rack-and-pinion), stroke length, precision grade, and enclosure. Belt modules are typically the most economical per meter for long strokes, while screw modules cost more but offer higher thrust. For an accurate quote, provide stroke, load, and speed requirements to a supplier.
A: For strokes beyond 4 meters, rack-and-pinion modules are generally more cost-effective per meter than screw modules because screws are limited by whipping and require support. Belt modules are also economical for long strokes but may stretch. Rack-and-pinion modules scale well with length and are preferred for very long travel.
A: Total price = base module cost + per-meter cost × stroke. Doubling stroke does not double price because end blocks and assembly are fixed costs. For strokes up to 4 meters, belt modules are common; beyond that, splicing or rack-and-pinion is used. Always request a quote with your specific stroke to get an accurate price.
