When Using Linear Guides, What Precautions Should Be Taken?

Linear guides, as precision mechanical components, must be handled with strict and standardized attitudes during their usage process. Even if high-quality and high-performance linear guide products are selected, improper operation or maintenance can not only fail to fully utilize their designed performance but also easily lead to premature damage of the guides, affecting the normal operation of the equipment.

1. Cleaning and inspection

Before installation, thoroughly clean the mechanical mounting surface to remove burrs, dirt, and metal shavings. Carefully inspect the surfaces of the guide rails and blocks for any dents or scratches. Since guide rails are usually coated with anti-rust oil at the factory, use specialized cleaning oil to clean the reference surface before installation. After cleaning, promptly apply low-viscosity lubricating oil to prevent rust on the metal surfaces.

2. Precision calibration and standardized installation

During installation, ensure that the flatness, straightness, and perpendicularity of the rail mounting surface meet the design standards, using tools such as right-angle squares and spirit levels for precise calibration. The installation of the rails and blocks must strictly follow the manual procedures, using a torque wrench to tighten the screws to the specified torque, to avoid uneven force distribution due to installation errors, which could affect the precision and service life of the rails.

3. Component compatibility and protection

Ensuring that the models of the guide rails, blocks and related accessories are exactly matched. It is strictly prohibited to mix products of different specifications or brands. During the installation process, it is strictly prohibited to strike or collide the guide rail and block forcefully to avoid damaging the internal precision structure.

4. Load and speed control

Operate strictly according to the rated load and motion parameters of the linear guide rail, avoiding overloading and overspeeding. In conditions with impact loads or vibrations, additional cushioning and vibration-damping devices must be installed to prevent deformation or damage to the guide rail due to excessive force.

5. Maintenance of lubrication system

Regularly lubricate the guide rails. Select the appropriate lubricant (lubricating oil or grease) based on the type of guide rail (such as high-speed, heavy-load, etc.), and strictly follow the specified lubrication cycle and dosage. For instance, low-viscosity lubricating oil is recommended for high-speed guide rails, while high-viscosity grease is needed for heavy-duty guide rails.

6. Environmental protection measures

Avoid operating linear guides in damp, high-dust or corrosive gas environments. If it is impossible to avoid such an environment, protective measures should be taken, such as installing protective covers, using sealing blocks or choosing anti-corrosion guide rail products, to prevent rust or impurities from entering the guide rail surface and affecting the operating accuracy.

7. Daily operation monitoring

Check the operation status of the guide rail every day, observe whether the block moves smoothly, and check for any abnormal noise or jamming. At the same time, check the tightness of the screws and the lubrication condition. If any abnormality is detected, the machine must be stopped immediately to troubleshoot the fault.

8. Regular comprehensive maintenance

Regularly carry out in-depth maintenance on the guide rails, including cleaning the surface, detecting the degree of wear, and measuring changes in accuracy, etc. For guide rails and blocks that are worn beyond the limit or have inaccurate precision, they should be replaced in a timely manner to ensure the processing accuracy and operational stability of the equipment.

9. Archival records and analysis

Establish a usage and maintenance file for linear guides, detailing the installation time, operation data, maintenance content and fault conditions. Through the analysis of historical data, summarize the patterns of potential problems, formulate preventive maintenance plans in advance, and optimize the service life of the guide rails.
