Airtac LGC Series Cross Roller Guide Rail LGC6R22
The AirTAC Airtac LGC Series Cross Roller Guide Rail LGC6R22 is a crossed roller guide using Ø6.0 mm precision rollers. Rollers are held in a cage in alternating orientation between hardened V-raceways, giving line contact instead of point contact — much higher rigidity and accuracy than a ball guide of similar size. It does NOT recirculate, so travel is set by rail length and the cage travels about half the stroke.

About the Airtac LGC Series Cross Roller Guide Rail LGC6R22
LGC6R22 is a spare roller cage for the AirTAC LGC family, listed in the manufacturer's parts table as a cage-and-roller set: 22 rollers of 6.0 mm diameter held in crossed orientation. It is not a rail, it is not a complete guide and no rail is supplied. The code itself carries no row arrangement, rail length or accuracy grade, because on a crossed roller guide those belong to the complete guide, which does not recirculate and is therefore limited in travel by its rail length.
The per-roller figures for size 6 are 3175 N dynamic and 2550 N static per roller. Note that the static value is the smaller one - the reverse of recirculating ball guides, where static usually exceeds dynamic - so sizing habits learned on ball products do not transfer. Scale matters too: going from a 1.5 mm to a 6.0 mm roller multiplies diameter four times but lifts the per-roller dynamic rating roughly twenty-five times, from 125 N to 3175 N.

Specifications follow the official AirTAC LGC catalogue. Load ratings are stated PER ROLLER, not per guide — total capacity depends on how many rollers the cage carries, which is why the roller count is part of the order code. Maximum stroke and tightening torques are given in the catalogue tables; ask us for the figure for your size. This item is a roller cage only — neither a rail nor a complete guide.

Where the Airtac LGC Series Cross Roller Guide Rail LGC6R22 Is Used
Keeping X-ray equipment slides serviceable
Slide sections of X-ray equipment demand precise, repeatable motion. Holding a 22-roller size 6 cage as a planned spare means a drifted or contaminated cage can be exchanged without scrapping an expensive matched rail set.
Optical test instrument repair
When an optical test instrument's traverse loses smoothness, the cause is often a damaged cage rather than worn rails. Swapping in LGC6R22 and re-running the dial-indicator setup restores the original motion quality.
Semiconductor metrology stage rebuild
During a rebuild of a wafer inspection stage, engineers renew the cage, verify each rail with an indicator and retighten mounting screws in sequence through the full stroke to hold the assembly's rated accuracy.
Is the Airtac LGC Series Cross Roller Guide Rail LGC6R22 the Right Guide?
Order LGC6R22 when the rails and slide of an existing size 6 LGC assembly are in good condition and only the cage needs renewing. If you are designing a slide from scratch, specify a complete LGC guide instead; a cage cannot run without its rails. Travel beyond roughly half a metre, or a preference for a sealed recirculating unit that installs bolt-on style, points to the LSH series, while light, small-envelope duties suit LRM.
Before ordering, check four things: that the form really is a cage spare; that size matches by both roller diameter and roller count (6.0 mm, 22 rollers); that the cage stays with its own matched rail set, since mixing rails from different sets voids the accuracy guarantee; and how the parent guide will be set up - LGC is assembled in place with a dial indicator, and clearance or preload is raised through adjusting screws, a pressure plate or a taper block as rigidity demands grow.
Quick checklist
- ✓ Complete set, carriage only, or rail only?
- ✓ Worst-case moment, not just straight load
- ✓ Travel length and mounting space
- ✓ Stroke shorter than the rail allows for cage travel
- ✓ Clearance method: screws, plate or taper block
- ✓ Pairing code, if replacing a part
Installation & Maintenance Notes
- check Mounting surface must be ground or finish-milled.
- check Torque the rail screws per the recommended figures, in sequence.
- check Keep the mounting corner radius inside the stated R maximum.
- check Centre the roller cage on the rail during assembly.
- check Adjust with a dial indicator over the full stroke.
- check Never mix rails from different sets — accuracy is matched per set.
- check Installation by qualified personnel per AirTAC docs.
Airtac LGC Series Cross Roller Guide Rail LGC6R22 FAQ
Size 6 gives a 6.0 mm roller diameter, a dynamic load rating of 3175 N per roller and a static load rating of 2550 N per roller, with 22 rollers in this cage. Row type, rail length and accuracy grade are not part of a cage code and stay null until matched to a complete guide. Because total guide capacity depends on load distribution across all rollers, the catalogue publishes no per-guide figure - confirm sizing with us before committing.
It is the cage-and-roller subassembly from the LGC parts table - here, 22 rollers of 6.0 mm held in crossed orientation. It is not a rail and not a complete guide, and no rail comes with it. It is sold on its own because the cage is the part most likely to drift: high speed, acceleration, eccentric load or vibration can shift it, and several full strokes of the slide normally walk it back towards centre. On vertical axes, leave extra stroke margin, since gravity makes drift accumulate in one direction.
