3.2 Inspection of the Bearing Guide Rail Surface

● Visual Inspection Check the surface of the guide rail for scratches, wear, rust, or other defects.

● Parallelism Inspection Check the parallelism of the guide rails to ensure both sides are in the same plane.

● Straightness Inspection Use a precision ruler or laser leveling instrument to check the straightness of the bearing guide rail.

● Wear Inspection Measure the degree of wear on the guide rail to determine if replacement or repair is necessary.

3.3 Slider Internal Inspection

● Ball Inspection: Check whether the ball or roller in the slider is worn, deformed, or missing.

● Circulation System Inspection: Check whether the circulation system in the slider is unobstructed and free from blockages or damage.

● Sealing Inspection: Check whether the slider seal is aged, damaged, or deformed to ensure sealing performance.

● Lubrication Inspection: Check the lubrication inside the slider to ensure sufficient lubricant and no contamination.

3.4 Cleaning and Maintenance

● Cleaning Steps: Use a special cleaning agent or kerosene to clean the bearing guide rails and sliders, removing oil and impurities.

● Drying Treatment: After cleaning, wipe with a clean cloth and place in a dry, ventilated area to air dry naturally.

● Lubrication and Maintenance: Apply an appropriate amount of lubricant to the guide rail and slider surfaces to maintain good lubrication.

● Regular Inspection: Periodically inspect the guide rails and sliders to identify and resolve potential issues promptly.

4. Installation and Debugging After Disassembly

4.1 Preparation Before Installation

● Prepare Tools: Ensure the installation surface is clean, flat, and free from oil, dust, or other impurities.

● Inspect the Guide Rails: Check for scratches, rust, or other defects on the guide rail surface to ensure quality.

● Prepare Tools: Gather required tools (e.g., screwdrivers, wrenches) according to installation requirements.

● Measure the Size: Accurately measure installation dimensions to ensure precise positioning of the bearing guide rails.

4.2 Installation Order and Method

Fix the Guide Rails Fix the guide rails on the installation surface according to the requirements of the design drawings to ensure that the guide rails are stable and firm.

Install the Slider Install the slider on the guide rail in sequence, paying attention to the matching of the slider and the guide rail.

Tighten the Screws Use appropriate tools to tighten the screws on the slider to ensure that the slider is tightly combined with the guide rail.
