A: Linear guides and ball screws are paired in modern motion systems because they complement each other’s benefits. Ball screws deliver force and accuracy to whole systems while linear guides maintains high rigidity and minimizes vibration. They two together create a high-performance linear motion system capable of long service life, repeatable precision and energy efficiency.

In practice:
Ball screws = Power transmission → transfers torque into accurate linear displacement.
Linear guides = Motion guidance → controls direction, reduces friction and resists external loads.

A: The slide rail has the ability to self-align. The DF (45°-45°) combination from the arc groove is installed with the elastic deformation of the steel ball and the transfer of the contact point, even if the mounting surface is deviated, it can be absorbed by the linear rail slider, resulting in the effect of automatic centering ability and obtaining high-precision and stable smooth movement. Moreover, the use of four-row circular arc groove, with the four-row steel ball and other 45 ° contact angle, so that the steel ball can achieve an ideal two-point contact structure, can bear the load from the up, down, left and right directions, and can improve the rigidity of the slide rail through preload adjustment, so as to achieve the requirements of high precision.

TZ Roller Guides are ideal for heavy-duty CNC machines where maximum rigidity and greater load capacity are critical. Unlike ball types, roller elements provide a larger contact area, reducing deformation under extreme loads.

A: Use Stainless Steel (TG/TGN series) for cleanrooms, medical devices, or acidic environments. For heavy-duty industrial loads where wear resistance is the priority, alloy Steel is the superior choice. Know more about the Selection of Linear Guides Material, read IMTEK blog for practical guide.

A: Proper linear guides installation is critical to a best performance and high precision linear guides system.
Start by preparing the mounting surface: ensure it’s clean, flat and free from burrs. Carefully align mounting holes of rails with the machine base. Insert bolts and tighten them gradually in a crisscross pattern to avoid stress concentration. During installation, use a torque wrench to achieve specified torque. Apply suitable lubrication to the rails and blocks before operation. Finally, run the block along the rail to confirm smooth, uniform motion without vibration or binding. Correct installation guarantees long service life and accuracy.

Proper installation is critical for accuracy. Ensure the mounting surface is clean and flat, align the rails carefully, and tighten bolts in a crisscross pattern using a torque wrench. Refer to our Installation Manual (PDF) for step-by-step guidance.

A: For most industrial applications, we recommend lubrication every 100km of travel or every 3 to 6 months. High-speed or dusty environments require more frequent maintenance.

The E2 Lubricant Kit features a high-oil-content reservoir that automatically supplies lubricant to the rail grooves. It can extend maintenance intervals up to 4000km, making it ideal for systems with restricted access.

A: IMTEK Linear guideways have been through preservative treated before leaving IMTEK factory, if you will not use the products within a month, we highly suggest you doing regular anti-rusty work in light of temperature in different area. Please contact IMTEK for further information.

Noise is often caused by a lack of lubrication, misalignment, or dust ingress. Use our Troubleshooting Guide to check for smooth ball circulation and clean the tracks immediately; if noise persists, contact our tech support.

A: Only if you purchased an Interchangeable Type guide. For high-precision (P-grade or above) sets, blocks and rails are ground as a matched pair and should not be swapped.

A: Noise is usually caused by lack of lubrication, misalignment, or ingress of dust. Clean the tracks immediately and check for smooth ball circulation. If the noise persists, contact our tech support.

In dusty areas, ensure you are using appropriate dust-proof accessories, such as metal scrapers and double oil scrapers. Regularly wipe down the rails and check that the dust-proof sheets are intact to prevent ingress. If you want to know more about how to maintain your linear rails and sliders, please check IMTEK Video center.

Yes, we provide various Surface Treatment Options, such as chrome-plating processes, to protect your linear guides and rails in harsh or corrosive environments. IMTEK has our own material factory, enlarging our production lines to be more effective from the raw materail to final products.

In most cases, the guide itself is not the main source of vibration. The axis may be entering a resonance zone where the machine structure, mass distribution, drive settings, and motion speed interact with each other. At those specific speeds, chatter or vibration can become much more noticeable.For more practical methods to reduce vibration and chatter in linear motion systems, see our guide on linear guide noise reduction engineering solutions.

A stiffer guide can shift the natural frequency of the axis into the machine’s operating range, which may make vibration more visible instead of reducing it. Higher preload also increases internal friction and drive force, so the structure may be excited more strongly during acceleration and deceleration.You can learn more about preload behavior and motion stability in our engineering guide to linear rail preload.

When the bolts are loose, the guide can float slightly and may temporarily hide mounting errors. After tightening, the guide is forced to conform to the mounting surface geometry, so flatness or straightness errors can turn into internal preload and binding.Proper rail alignment and tightening methods can strongly influence motion smoothness during assembly. Learn more in our guide to linear guide installation and alignment

This usually indicates mounting errors, end-plate distortion, or screw alignment issues that become more pronounced near the ends of the stroke. Internal preload may also increase locally in these regions, which makes the ends feel heavier while the middle still moves more smoothly.

Preload removes internal clearance and increases stiffness, which improves positioning accuracy and vibration resistance under load. However, higher preload also increases friction and rolling resistance, so the system becomes more sensitive to mounting accuracy, lubrication quality, and drive torque limits.

High preload increases static friction and breakaway torque, which can create stick-slip behavior at low speeds. This is especially noticeable in systems using smaller servo motors or stepper drives.

During acceleration and deceleration, the drive system must overcome inertia and changing friction forces at the same time. Any imbalance in stiffness, preload, alignment, or structural rigidity becomes more visible in these motion phases, and control gain settings can also amplify vibration or noise.

.

When two guides are mounted in parallel, even small differences in spacing, height, or straightness can force them to fight each other mechanically. Each rail may track well on its own, but once connected through a carriage or machine structure, the mismatch can show up as binding, uneven resistance, or increased running torque.

Bolt tightening can slightly deform the rail and the mounting structure, especially on flexible machine frames. Different tightening sequences redistribute stress along the axis, which can shift tight spots, change preload, or alter running resistance.

At higher feed rates, dynamic deflection, vibration, and servo following error become much more significant. Mechanical imperfections that are acceptable at low speed may become limiting factors once acceleration, cutting force, and machine vibration increase during high-speed operation.
