In the field of modern industrial automation, high-precision linear motion components are essential for ensuring equipment efficiency. However, even when using high-performance long oval flange bearings (such as the SQ LMH20LUU) manufactured from premium GCr15 bearing steel, the expected precision cannot be achieved if installation or maintenance is improper. To extend equipment lifespan and minimize downtime risks, please strictly adhere to the following operational standards:
SQ LMH20LUU
1. Prevent Corrosion: Avoid Direct Hand Contact
Linear guides and bearings are precision components whose surfaces are extremely sensitive to moisture and acidic substances.
Standard Operation: When handling bearings directly by hand, ensure you have thoroughly washed away any perspiration. Apply high-quality mineral oil to your hands before proceeding.
Seasonal Protection: During rainy or summer seasons when humidity is high, pay extra attention to anti-rust treatments to ensure the internal raceways of the linear guide remain free from oxidative corrosion.
2. Maintain Environmental Cleanliness: Beware of Invisible Threats
Even microscopic dust particles entering the guide rail can severely impact precision.
Reduce Wear: Keep the linear bearings and their surrounding environment clean. This prevents fine dust from increasing wear, vibration, and noise levels.
Quality Commitment: As the manufacturer of the LMH20LUU linear guide, SQ adheres to the principle of "Do not produce, do not accept, and do not ship defective products." Maintaining a clean environment is a prerequisite for sustaining factory-grade precision.
3. Careful Installation: Avoid Violent Impact
The structures of precision parts are delicate; incorrect force during installation can cause permanent damage.
Prohibit Violence: Forceful stamping is strictly prohibited during installation. Never use a hammer to strike the guide rail or the bearing flange directly.
Pressure Management: Do not allow pressure to be transmitted through the rolling elements (steel balls). Doing so will cause indentation in the raceways (brinelling), compromising smooth operation.
4. Selection of Proper Installation Tools and Materials
Using professional tools is the key to ensuring precise alignment of the linear guide shaft.
Specialized Tools: Utilize appropriate and accurate specialized installation tools whenever possible to avoid deformation caused by improper equipment.
Material Safety: During cleaning and installation, strictly avoid using cloths or short-fiber materials. These can shed fibers that enter the bearing interior and obstruct the circulation system.

While the inherent quality of a linear guide significantly dictates performance, improper handling, poor environmental conditions, or careless installation will compromise its effectiveness. The above precautions are summarized by the manufacturer of the SQ-LMH20LUU. Please contact us for further guidance on usage and maintenance.
