FAQs: Custom Linear Guides for Robotics Applications
Custom linear guides are motion systems that are tailored for a specific application. These systems allow for linear displacement with great precision through either rolling or sliding contact of the guide rails and the carriages. Different types of these systems include profiled rail guides with recirculating ball or roller bearings, square rail guides for heavy-load applications, miniature guides for compact assemblies, crossed roller guides which allow for multi-axis constraint, dovetail guides for manual adjustment, custom profile rails for specific mounting requirements, and integrated guide systems which incorporate motion systems with measurement motion systems and cable guides.
Bearing steel such as 52100 and SUJ2 gives the linear guides outstanding hardness that exceeds 60 HRC. Guides made of such steel can withstand great amounts of wear and fatigue. This is essential for the travelling systems as they provide thousands of travel cycles. Tool steel is another great option of which can supply excellent machinability before hardening, and on top of that, is capable of providing surface hardness that can range between 58 to 62 HRC. For applications that require stainless steel, 440C and 17-4 PH are great options as they provide stainless steel 440C and 17-4 PH are great options as they provide corrosion resistance for cleanroom and food processing applications. Aluminum is excellent for lightweight guides. This is especially important for high-speed applications that require rapid acceleration of greater than 5 g.
Custom linear guides are made using several CNC processes. Surface grinding makes the flat reference surfaces. These have straightness of 0.0005 inches per foot and a flatness of 0.001 inches over a length. Precision profile grinding creates the V-grooves, dovetails, and rail profiles along with the ±0.0002 inches dimensional accuracy. Precision milling makes the mounting holes, lubrication grooves, and carriage pockets. Induction hardening targets selective surface hardening of the running surfaces to 58-62 HRC. Lapping is used to achieve near surfaces of Ra less than 0.05 microns to allow frictionless sliding. Wire edm is used to cut the intricate carriage geometries in hardened materials.
Custom linear guides guarantee straightness of 0.0005 inches per foot for the guide rails allowing for correct linear motion. 0.0003 inches of parallelism is attained between the running surfaces, eliminating bind. Mounting surfaces achieve a flatness of 0.001 inches. Running surfaces present a surface finish of less than 0.05 Ra microns to allow for friction minimization. Rail profile dimensions are maintained within ±0.0002 inches for correct carriage fit. Height tolerances of ±0.0005 inches provide precision for multi-rail systems with preload control.
Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.
All quality standards are met through ISO 9001 certified quality management systems for each component. This also includes complete traceability of materials, certifications of heat treatment, dimensional verification against design specifications, straightness and flatness measurement reports, hardness testing on running surfaces, and documentation for precision motion components in industrial robotics. These components require positioning accuracy of 0.01 millimeters, straightness within 5 microns per meter, and withstand millions of travel cycles, proving the utmost durability.

Standard custom rail profiles with basic grinding require 12–18 business days, while precision ground and lapped guide systems with selective hardening need 5–6 weeks including heat treatment and final grinding operations. Prototype guide sets can be completed in 8–12 days for rapid motion system testing and alignment validation.
Definitely. For industries like semiconductor and metrology we build ultra-precision guides that have a straightness of 2 microns per meter. We have also built heavy-duty guides for industrial gantries that support loads more than 50,000 Newtons. We have high-speed guides with optimized geometry for linear speeds more than 10 meters per second. For underwater robotics and marine applications, we manufacture guides that are corrosion resistant. We build vacuum guides for semiconductor processing equipment, and combined integrated guides with encoder scales, limit switches, covers, and protective covers.
Linear guide performance is precision machined enhances. Linear guides maintain a positioning error of 10 microns over long lengths critical for CNC machines and coordinate measuring systems. Guides achieve remarkable straightness of 0.0005 inches a foot. Supports achieve a parallelism of 0.0003 inches. Ultra-smooth lapped surfaces Ra below 0.05 microns reduce guide drive forces close to 50% and permit fine control of guide movement. Ultra-smooth lapped surfaces guides achieve 100Km of uninterrupted travel at a hardness of 58-62 HRC. Safe 58-62 HRC hardness assists ultra-smooth lapped surfaces maintain 100Km of uninterrupted travel. Adjusted dimensions assist maintain preload and control friction. Quality manufacturing assists in obtaining reliable precision motion control in multi-axis robots, inspection gantries, and laser processing systems. Quality manufacturing assists in obtaining precision control motion in multi-axis robots, inspection gantries, and laser processing systems. Automated assembly machines also benefit from the precision control motion.
