Why choose AirTAC Linear Guides?
In today's fast-moving automation landscape, long lead times and inflated costs shouldn't hold your build back. AirTAC precision linear guides offer a premium-grade, highly reliable alternative to traditional motion suppliers, combining smooth precision with exceptional value.
- Cost-Effective Performance: Get high-precision linear guidance at a competitive price point, optimizing your bill-of-materials (BOM) cost.
- High Availability: We hold inventory on-site, and cut rail to length in our machine shop, drastically reducing lead times for critical maintenance, repairs, and new machine builds.
- Self-Aligning & High Rigidity: Engineered with a 45°-45° contact structure to accommodate minor mounting surface misalignments while delivering equal load capacity in all four directions.
- Engineered Value-Add: Supported directly by our experienced technical team—we don't just ship boxes, we verify application fit and prepare your hardware for immediate installation.
Value-Added Services: Precision In-House Rail Cutting
Need non-standard rail lengths? Avoid rough hand-cuts or job-site burrs.
We do more than just stock inventory, our facility is equipped with a dedicated 14" Metallographic Sectioning Saw specifically calibrated for hardened linear guide rail materials.
- Clean, Cold Cut Finish: Metallographic cutting prevents thermal damage to the hardened raceway steel, maintaining the integrity and hardness profile of the rail.
- Exact Tolerances: We cut rails precisely to your mechanical layout or CAD specifications.
- Ready for Assembly: Every rail is deburred and end-prepped so it arrives at your facility ready to bolt straight into your structure.
We stock both Flange and Square block styles, along with matching rail profiles across two versatile series:
| | LSH Series (Standard Profile) | LSD Series (Low-Profile) |
| Profile Design | Standard height profile for robust, traditional mechanical architectures. | Compact, reduced overall height for tight-envelope applications. |
| Stocked Sizes | Sizes 15, 20, 25, 30, 35, 45 | Sizes 15, 20, 25 |
| Available Block Styles | Flange (Through & Tapped Holes) & Square Types | Flange (Through & Tapped Holes) & Square Types |
| Load Orientation | Equal load rating in radial, reverse-radial, and lateral directions. | Equal load rating in radial, reverse-radial, and lateral directions. |
| Primary Advantage | Maximum load capacity and structural rigidity for standard automation. | Space-saving miniaturization without sacrificing load performance. |
Core Technical Highlights
- Self-Adjustment Capability: The X-shaped 45°-45° curved raceway groove structure provides natural self-aligning capabilities. This design absorbs small irregularities on mounting surfaces, delivering smooth, friction-free linear travel without binding.
- Equal Load Capacity in Four Directions: The four-row steel ball construction maintains ideal two-point contact with the raceways at a 45° angle. This enables both the LSH and LSD series to bear equal radial, reverse-radial, and lateral loads, offering flexible mounting in horizontal, vertical, or inverted orientations.
- Interchangeability & Ball Retention: Precision-controlled manufacturing guarantees consistent dimensional tolerances. Built-in ball retainers prevent steel balls from dislodging during carriage removal, making assembly, block substitution, and maintenance simple and stress-free.
