Airtac LGC Series Cross Roller Guide Rail LGC6R32
The AirTAC Airtac LGC Series Cross Roller Guide Rail LGC6R32 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 LGC6R32
The LGC6R32 is the roller cage subassembly for AirTAC's size 6 LGC crossed roller guide: 32 hardened cylindrical rollers, 6.0 mm in diameter, held in a cage that keeps them in alternating crossed orientation between the V-raceways. Because the rollers make line contact rather than the point contact of a ball, the assembly is far stiffer than a ball guide of similar size. To be clear about the form: this code is NOT a rail and NOT a complete guide, and no rail is supplied. The rails are ordered separately as a matched set, so never combine them with rails from a different set.
Each roller in this cage is rated 3175 N dynamic and 2550 N static - per roller, not per guide. Note that the static figure sits below the dynamic one here, the reverse of a ball guide, so do not size on the larger number out of habit. Total capacity rises with the number of rollers in contact, which is why a 32-roller cage suits heavier short-travel duties than a small-count one. Remember too that when the slide moves, the cage travels with it by roughly half the stroke; if it ever drifts out of position, running the slide through several full strokes brings it back near centre.

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 LGC6R32 Is Used
Rebuilding a PCB drilling machine spindle slide
When a drilling machine's short-travel slide loses smoothness after years of vibration, swapping in a fresh 32-roller size 6 cage during the rebuild restores the crossed-roller geometry at a fraction of the cost of new rails.
Servicing an optical bench carriage
A metrology lab maintaining an optical bench carriage can renew the roller cage without disturbing the fitted and dial-indicator-adjusted rails, keeping the bench's alignment work intact.
Overhauling an X-ray equipment slide section
X-ray equipment slides demand high rigidity over short travel. A cage inspection and replacement during overhaul addresses roller wear before it shows up as positioning error in the imaging path.
Is the Airtac LGC Series Cross Roller Guide Rail LGC6R32 the Right Guide?
Confirm the form first: LGC6R32 is a cage spare only, so order complete LGC guides when building a new axis and this cage when a drifted or damaged cage needs replacing. Size 6 is the top of the LGC range - scaling the roller from 1.5 mm to 6.0 mm is a four-fold diameter change, yet the dynamic rating per roller rises from 125 N to 3175 N, roughly twenty-five times. Check the roller count of the cage in the guide being serviced, choose the row arrangement (A three-row or B four-row) and rail length of the complete guide it belongs to, and take the rail length from the manufacturer's maximum-stroke table with the working stroke set slightly shorter. Grade H complete guides are the stocked accuracy; grade P is available to order. Plan the clearance method - adjusting screws, a pressure plate or a taper block in rising order of rigidity - into the surrounding machining, and budget time for the dial-indicator fitting and adjustment. If your travel exceeds roughly half a metre or you want a sealed recirculating assembly, step across to LSH instead; for light duty in a small envelope, LRM is the leaner choice.
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 LGC6R32 FAQ
It is a size 6 LGC cage carrying 32 rollers of 6.0 mm diameter, each rated 3175 N dynamic and 2550 N static, per roller. Rail length, row arrangement and accuracy grade are not properties of a cage code; they belong to the complete guide it serves. Total capacity scales with the roller count through load distribution and contact angle, so no per-guide total is published - send us the sizing question and we will work it through with you.
Neither. It is the cage-and-rollers subassembly listed in the manufacturer's parts table, and no rail is supplied. It is sold separately because a drifted or damaged cage is an inexpensive repair compared with replacing a complete matched set. Remember that the rails are accuracy-matched as a set and must never be mixed between sets.
