The kit includes carbon steel linear shafts (HRC62 Hardness) and aluminum alloy support rails and slide blocks. The slide blocks contain ball bearings for smooth movement.
Installation Steps:
- Prepare Mounting Surface: Ensure the surface where the linear rails will be mounted is clean, flat, and stable.
- Position Rails: Place the aluminum support rails in the desired position. Utilize the pre-drilled mounting holes for accurate alignment.
- Secure Rails: Fasten the support rails securely to the mounting surface using appropriate fasteners (not included). Ensure the rails are parallel and level to prevent binding.
- Install Slide Blocks: Slide the SC20 slide blocks onto the linear shafts. The blocks are designed for easy integration.
- Attach to Moving Part: Secure the slide blocks to the moving component of your machine or DIY project. The blocks have mounting holes for this purpose.
- Verify Movement: After installation, manually move the slide blocks along the rails to ensure smooth, unhindered motion. Check for any binding or excessive play.

3. Operating Principles
The VEVOR Linear Rail Slide system operates on the principle of rolling friction, utilizing internal ball bearings within the slide blocks to provide low-resistance movement along the hardened linear shafts. This design ensures high precision and minimal noise during operation.

The chrome-plated surface of the linear shafts provides corrosion resistance, allowing for reliable performance even in environments with moisture. The robust construction ensures the system remains highly stable and non-deformable under load, maintaining accuracy over time.

Precision details such as minimal linear deviation error (≤ 80 µm / 1000 mm) and shaft roundness error (≤ 3 µm) contribute to the system's accurate motion capabilities.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your VEVOR Linear Rail Slide system.
Cleaning:
- Periodically wipe down the linear shafts and slide blocks with a clean, lint-free cloth to remove dust, debris, and old lubricant.
- For stubborn grime, use a mild, non-corrosive cleaning agent. Ensure all cleaning residues are removed before re-lubrication.
Lubrication:
- The slide blocks are pre-lubricated from the factory. However, for continuous smooth operation, especially in high-use applications, periodic re-lubrication is recommended.
- Apply a thin layer of high-quality linear bearing grease to the linear shafts. Move the slide blocks back and forth several times to distribute the lubricant evenly.
- Frequency of lubrication depends on usage and environmental conditions. Inspect regularly for signs of dryness or increased friction.
Inspection:
- Regularly inspect the shafts for any signs of wear, scratches, or corrosion.
- Check the slide blocks for any damage or excessive play.
- Ensure all mounting bolts are tight and secure.
5. Troubleshooting
If you encounter issues with your linear rail slide system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Binding or Sticking Movement | Misalignment of rails; insufficient lubrication; debris on shafts; damaged bearings. | Check rail parallelism and levelness; clean shafts and re-lubricate; inspect for foreign particles; replace damaged components. |
| Excessive Play or Looseness | Worn bearings; loose mounting bolts; incorrect component sizing. | Tighten all mounting bolts; inspect bearings for wear and replace if necessary; ensure correct shaft and block sizes are used. |
| Increased Noise During Operation | Lack of lubrication; presence of debris; worn bearings. | Clean and re-lubricate the system; remove any debris; replace worn bearings. |
| Corrosion on Shafts | Exposure to moisture without proper protection. | Clean off corrosion (if minor); apply rust preventative lubricant; ensure proper environmental conditions or protective measures. |
