About the AirTAC LGC3A
The AirTAC LGC3A is an LGC crossed roller guide with Φ3 mm rollers, supplied as a complete three-rail set (A): rails, roller cages and end screws. Each roller is rated C 640 N dynamic and C0 610 N static (203 N allowable load), at 5 mm roller pitch.
Crossed roller guides are non-recirculating: precision rollers set alternately at right angles run between V-grooved rails, so friction is very low while the rigid rails carry high loads. The rails are stainless steel and the rollers are JIS B 1506 G2 grade. Main and secondary rails are the same length. This page lists 50 – 300 mm rails with 7 – 40 rollers per cage.

Where the LGC3A Is Used
Measuring and optical equipment
Optical test instruments, optical benches and X-ray equipment slides.
PCB and electronics machines
Slides of printed circuit board drilling machines and inspection stages.
Precision stages
Short-stroke XY and Z stages that need high rigidity and accuracy.
Choosing the Right LGC3A Configuration
Start with the rail length: it sets the size of the slide.
Then the number of rollers per cage. More rollers carry more load but leave less stroke on a given rail length; the catalog's maximum-stroke table lists the stroke of each combination.
Accuracy is H (high) or P (precision). For a size or combination not listed, request a quote.
AirTAC LGC3A FAQ
A is a three-rail set and B a four-rail set; both use the same rollers and rail lengths. LGC6 is made as a four-rail set only.
