Introduction
The Linear Guide Rail 2000mm represents a robust long-stroke motion solution engineered for industrial applications demanding unwavering precision and stability over extended lengths. Crafted from high-grade hardened steel, the rail undergoes precision grinding to achieve exceptional straightness and flatness, ensuring smooth and accurate linear movement even under heavy loads. Its integrated sealing system effectively guards against contaminants like dust and debris, making it ideal for harsh environments such as CNC machining centers, large-scale automation systems, and heavy-duty material handling equipment. The 2000mm length provides ample travel for expansive workstations without compromising rigidity or alignment, reducing deflection and vibration for enhanced operational accuracy. Compatible with a range of slider blocks and mounting configurations, this rail offers versatility and reliability for demanding industrial uses.
| Feature Aspect | Description & Advantage |
|---|---|
| Ultra-Long Stroke Coverage | Effective stroke reaches 2000 mm, meeting the needs of large workpiece machining, long-distance material handling, wide-format scanning, and similar applications. Can be used as a single rail or spliced precisely to achieve even longer strokes (e.g., 4 m, 6 m). |
| High Rigidity Against Deflection | Rail cross-section and bolt hole layout are optimized for the 2 m length. A rib-reinforced structure designed using finite element analysis significantly improves bending stiffness. Effectively suppresses deflection even under heavy loads or high-speed motion. |
| High Precision Straightness | Manufactured with long-stroke dedicated precision grinding equipment; full-length running parallelism is controlled within 0.02 mm/2000 mm. Inspected with laser interferometers to ensure long-distance positioning and repeatability accuracy. |
| Four-Directional Equal Load Design | Gothic arch groove four-point contact structure with a 45° contact angle provides identical load ratings in radial, counter‑radial, and lateral directions, adapting to complex loading conditions. |
| Thermal Expansion Compensation Design | At 2000 mm length, thermal expansion/contraction due to temperature changes is significant (approx. 0.024 mm/°C for stainless steel). A fixed-end + supported-end mounting configuration is recommended to allow free axial expansion at one end; alternatively, low‑expansion‑coefficient materials can be selected. |
| Precision Splicing Option | If manufacturing or transportation is constrained, precision butt‑splicing technology can join multiple rail sections into a 2000 mm continuous rail. The joint is smooth and step‑free, allowing carriages to pass without any noticeable transition. Supports both on‑site and pre‑assembled splicing. |
| High-Rigidity Mounting Base Requirement | Must be paired with a stress‑relieved, high‑rigidity base (e.g., cast iron platform, granite platform, thick steel plate welded structure). The mounting surface flatness must be ≤ 0.05 mm/2000 mm to avoid rail distortion. |
| Multi‑Block Load‑Sharing Configuration | A single rail can be equipped with 2–4 blocks, optimizing load distribution and reducing the force on each individual block. Multiple blocks effectively resist overturning moments over long strokes, improving system stability. |
| Effective Protection & Lubrication | Can be equipped with stainless steel telescopic covers or accordion covers to prevent chips and dust from entering the raceway. Optional self‑lubricating units (e.g., QZ lubricator) greatly extend maintenance intervals, reducing upkeep costs over long strokes. |
| Corrosion Resistance Options | Available in martensitic stainless steel or with surface coating treatments, suitable for humid, corrosive environments or cleanrooms. |
| Standardized Interface & Interchangeability | Standardized rail mounting hole spacing; blocks and rails are interchangeable within the same series. Supports custom non‑standard lengths with flexible minimum order quantities. |
