2. Informació de seguretat
Observeu sempre les següents precaucions de seguretat per evitar lesions i danys a l'equip:
- Wear appropriate personal protective equipment (PPE) such as safety glasses and gloves during installation and maintenance.
- Ensure all power to machinery is disconnected before installing or performing maintenance on linear motion components.
- Handle linear rails and carriages with care. They can be heavy and have sharp edges.
- Avoid dropping or impacting the components, as this can damage precision surfaces and affect performance.
- Do not attempt to disassemble the carriage blocks unless specifically instructed, as this can lead to loss of ball bearings and damage.
- Ensure proper mounting and alignment to prevent binding or excessive wear during operation.

5. Configuració i instal·lació
Proper installation is crucial for optimal performance and longevity of your linear rail system.
5.1 Preparació
- Ensure the mounting surface is clean, flat, and free from burrs or debris.
- Verify that the mounting holes on your machine match the dimensions of the linear rail.
- Clean the linear rails and carriage blocks with a lint-free cloth and a suitable solvent (e.g., isopropyl alcohol) to remove any protective coatings or contaminants.
5.2 Carriage Installation/Removal
To prevent ball bearings from falling out, always use the provided plastic guide or a spare rail segment when installing or removing carriage blocks from the linear rail.
Figure 6: Correct procedure for installing/removing carriage blocks.
- **Removal (Top Image):** Do NOT slide the carriage off the rail without a guide. This will cause ball bearings to fall out.
- **Installation/Removal (Middle Image - Step 1):** Align the plastic guide (or a spare rail) with the end of the linear rail. Carefully slide the carriage from the rail onto the guide, or from the guide onto the rail.
- **Installation/Removal (Bottom Image - Step 2):** Ensure a smooth transition between the rail and the guide. The carriage should slide freely.
5.3 Rail Mounting
- Position the linear rail on the mounting surface, aligning the mounting holes.
- Insert the mounting screws and tighten them gradually and evenly along the entire length of the rail. Avoid over-tightening any single screw before others are snug.
- For dual rail systems, ensure both rails are parallel and coplanar to prevent binding and ensure smooth motion. Use precision alignment tools if necessary.
6. Funcionament
Once installed, the linear rail and carriage system provides precise and low-friction linear motion. Ensure that the load applied to the carriages does not exceed the specified dynamic or static load ratings (refer to Section 4.3). Operate the system within its intended speed and acceleration limits to maximize lifespan and maintain accuracy.
7. Manteniment
Regular maintenance helps preserve the performance and extend the life of your linear rail system.
- **Lubrication:** Apply a suitable lubricant (e.g., lithium-based grease or machine oil) to the rail and carriage blocks periodically. The frequency depends on the operating environment and usage intensity. Ensure lubricant reaches the ball bearing raceways.
- **Cleaning:** Keep the rails and carriages free from dust, chips, and other contaminants. Use a clean, lint-free cloth to wipe down exposed surfaces. Anti-dust caps are provided to help protect the internal components.
- **Inspection:** Regularly inspect the rails and carriages for signs of wear, damage, or corrosion. Check for smooth movement and any unusual noises. Address any issues promptly.
- **Tightness Check:** Periodically check the tightness of all mounting screws to ensure the rails remain securely fastened.
