Airtac LGC Series Cross Roller Guide Rail LGC3R10
The AirTAC Airtac LGC Series Cross Roller Guide Rail LGC3R10 is a crossed roller guide using Ø3.0 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 LGC3R10
LGC3R10 is a spare roller cage for AirTAC LGC size 3 crossed roller guides: the cage with its 10 cylindrical rollers, held in the alternating crossed orientation that gives these guides their line-contact rigidity, and nothing else. It is not a rail, not a rail-only item and not a complete guide, and no rail is supplied. For a full assembly you order a complete LGC code that includes row type, rail length and accuracy grade; this part exists because the manufacturer lists the cage separately in its parts table.
The rollers are 3.0 mm size 3 rollers, rated 640 N dynamic and 610 N static per roller - the rollers' own figures, not a rating for any finished guide. Ten rollers means ten line contacts sharing the work, and total capacity scales with that count rather than appearing as a published per-guide number. A cage is also the inexpensive part of an LGC assembly: spares run roughly $13 to $181 against $152 to $2024 for complete guides. Confirm the roller count of the cage you are replacing before ordering, and return the new one to the set it came from - accuracy on LGC is controlled as a matched set.

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 LGC3R10 Is Used
Optical bench cage replacement
A mirror-mount slide on a laboratory optical bench starts to run rough after the cage has drifted; a fresh LGC3R10 cage restores it without replacing the whole guide.
PCB drilling machine service
During scheduled service of a PCB drilling machine, swapping a worn 10-roller cage takes far less time than re-fitting and re-adjusting a complete guide set.
X-ray slide overhaul
Rebuilding the slide section of X-ray equipment: a dropped or indented cage is replaced with this spare, and the assembly is re-adjusted with a dial indicator before return to service.
Is the Airtac LGC Series Cross Roller Guide Rail LGC3R10 the Right Guide?
Ordering LGC3R10 is a maintenance decision, not a design one - for a new machine start from a complete LGC guide code with row type, rail length and accuracy grade. When replacing, verify the size (3, meaning 3.0 mm rollers) and the roller count (10) against the cage you are removing, and return the new cage to the set it came from: LGC accuracy is controlled as a matched set. If the real requirement is long travel or a sealed recirculating assembly, no cage is the answer - compare LSH; if duty is light and space tight, LRM may serve better. Budget the fitting, not just the part: the cage goes in per the manufacturer's procedure (on adjusting-side methods the end screw is removed and refitted), the slide is stroked to centre the cage, and mounting screws are tightened to the catalogue's recommended torque over the full stroke - take those figures from the datasheet or ask us.
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 LGC3R10 FAQ
Size 3 rollers of 3.0 mm diameter, 10 of them, with catalogue ratings of 640 N dynamic and 610 N static per roller. No row type, rail length or accuracy grade applies to this part code - it is a cage only. Total guide capacity scales with roller count rather than being a published per-guide figure, so confirm specific sizing with us.
No - it is the cage-and-roller subassembly from the manufacturer's parts table. It is not a rail, not a rail-only item and not a complete guide, and no rail is supplied. It is sold separately so that a drifted or damaged cage can be replaced cheaply - spares run roughly $13 to $181 against $152 to $2024 for complete guides - instead of scrapping the whole assembly.
