The 1200mm linear rail provides an optimal balance between structural stability and installation flexibility for medium-span applications. This versatile rail length is particularly suitable for industrial automation equipment, material handling systems, and precision measuring instruments where both space utilization and operational accuracy are critical requirements. Manufactured from high-grade steel and subjected to rigorous heat treatment, the rail maintains excellent straightness and wear resistance across its entire length. The standardized 1200mm dimension ensures compatibility with various machine layouts while minimizing the need for custom fabrication. With comprehensive accessory support including mounting brackets and end caps, this linear rail solution offers reliable performance for both original equipment manufacturing and system retrofit projects.
| Key Aspect | Description |
|---|---|
|
Long Stroke & High Rigidity |
The 1200 mm effective stroke meets the requirements of large equipment such as laser cutters, 3D printers, and long-stroke material handling systems. By increasing the rail cross-section and the number of mounting bolt holes, overall rigidity is maintained, preventing deflection. |
|
High Precision Straightness & Flatness |
Long rails demand extremely high flatness of the mounting base (typically ≤ 0.05 mm over the full length). Precision grinding technology ensures running parallelism within 0.02 mm, guaranteeing accurate long-distance positioning and repeatability. |
| Multi-Block Configuration & Load Sharing | Supports 2 to 4 blocks per rail, optimizing load distribution, reducing the load on each block, and extending service life. Multiple blocks effectively resist overturning moments over long strokes. |
| Mounting & Support Structure | Must be paired with a high-rigidity, stress-relieved mounting base (e.g., cast iron, granite, or thick steel plate) to avoid rail distortion caused by base deformation. Support points are recommended at intervals of 500–600 mm. |
| Thermal Expansion Compensation | At a length of 1200 mm, temperature changes cause significant expansion/contraction (approx. 0.012 mm/°C·m for stainless steel). A fixed + support end mounting configuration must be provided to allow axial free expansion at one end. |
| Optional Splicing Solution | If manufacturing or transportation constraints exist, precision butt splicing technology can join two rail sections to achieve an ultra-long stroke. The joint is smooth and step-free, ensuring unaffected carriage movement. |
| Environmental Resistance & Maintenance-Free Options | Long rails are commonly used in large automation equipment. Stainless steel material can be selected for rust resistance, or self-lubricating units can be equipped to reduce maintenance frequency over long strokes. |
