Key Measures to Prevent the Linear Guideway Damage

2025,06,10
Linear guides, as precision transmission components, directly influence the operational accuracy and stability of mechanical equipment. Improper usage can easily lead to component damage.?
?
Key precautions for linear slide rails:
?
I. Anti-rust and Corrosion Prevention
1. Hand Hygiene and Protection: Direct contact with Linear Guide Rail and carriage using bare hands is strictly prohibited. Before operation, thoroughly clean your hands with professional cleaning agents to ensure no residue of stains or sweat. If hand contact is unavoidable, wear dust-free gloves to prevent skin oils and moisture from adhering to the Linear Guide surface.
?
2. Lubrication and Protection: Before operation, evenly apply a layer of high-quality mineral oil to the linear guideway surface. This forms a protective film that isolates the guide rail from air and moisture. Mineral oil not only prevents rust but also provides lubrication, reducing friction within the linear motion guide.
?
3. Response to Special Environments: In high-humidity environments, in addition to regular anti-rust treatments, it is recommended to store linear guides in moisture-proof packaging. Install dehumidification equipment in the working environment, maintaining a relative humidity between 40% and 60% to effectively reduce the risk of rust.
?
II. Environmental Control Requirements
1. Visible Dust Removal: Linear Guideways demand a high level of cleanliness in the working environment. Regularly conduct comprehensive cleaning of the production workshop, using tools such as vacuum cleaners and dust-free cloths to remove visible dust from floors and equipment surfaces, keeping the work area tidy.
?
2. Invisible Dust Protection: Invisible particles like airborne dust and metal shavings generated during machining pose significant risks to linear guides and rails. Install air purification equipment in the workshop, set up dust curtains, or use sealed workspaces to minimize dust ingress. Additionally, equip linear motion rails with protective covers to effectively block dust and reduce guideway wear.
?
3. Environmental Monitoring and Maintenance: Regularly monitor the dust concentration in the working environment. If abnormalities are detected, promptly identify and address the sources of dust. Meanwhile, observe the linear slide assembly for increased vibration or noise during operation. If such issues arise, immediately stop the machine for inspection to prevent further deterioration.
?
III. Key Points of Installation
1. Pre-installation Inspection: Before installing linear ball bearing slides, conduct a comprehensive inspection of the linear guides and related components using professional testing tools. Ensure that dimensional accuracy, surface finish, and other parameters meet installation requirements. Check the mounting surface for flatness and cleanliness; if there are scratches, burrs, or other defects, repair or replace the surface promptly.
?
2. No Forceful Installation: During installation, using tools like hammers to strike or force the cnc linear rail into place is strictly prohibited. Such actions can cause deformation of the guide or damage to internal ball bearings. Instead, use specialized installation tools and follow the correct installation procedures step by step.
?
3. Technical Installation Adjustment: In case of installation issues, rely on professional measuring instruments and installation equipment for precise adjustments. Adjust the tightening torque of mounting bolts or use shims to fine-tune the linear guide height, ensuring accurate positioning. After installation, conduct a trial run to check for smooth operation and any signs of jamming, guaranteeing installation quality.
