Airtac LGC Series Cross Roller Guide Rail LGC1R6
The AirTAC Airtac LGC Series Cross Roller Guide Rail LGC1R6 is a crossed roller guide using Ø1.5 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 LGC1R6
Size 1 is the smallest LGC format, built around 1.5 mm rollers, and LGC1R6 is its lightest stocked cage: 6 rollers in alternating (crossed) orientation, sold as the cage-and-roller subassembly alone. It is not a rail and not a complete guide - no rail is included. Like every LGC guide, the design does not recirculate, so the cage stays captive and travel is set by the rail length of the host set.
Ratings are quoted per roller: 125 N dynamic and 120 N static for size 1, with static slightly below dynamic - opposite to ball-guide practice. Six rollers suit short cages on compact slides, and the per-roller unit matters because total capacity scales with the count across the contact lines rather than being published as a guide total. Fitting a new cage means dial-indicator adjustment in place: this is a fitted part, not a bolt-on cartridge.

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 LGC1R6 Is Used
Pick-and-place module repair
Compact pick-and-place heads use short, stiff slides where a 6-roller cage fits the tight envelope. A shelf spare cuts downtime when drift shows up as placement error.
Microscope stage servicing
Inspection microscope XY stages run on small crossed roller guides. Swapping a worn 6-roller cage and re-adjusting with a dial indicator removes the stick-slip that ruins focus repeatability.
Lens edging machine overhaul
Optical lens edging machines need vibration-free feed over short travels. Replacing an indented cage during annual overhaul protects lens surface finish.
Is the Airtac LGC Series Cross Roller Guide Rail LGC1R6 the Right Guide?
Confirm the form first - LGC1R6 is a spare cage for an existing size 1 guide, so a new build should order a complete LGC set. When travel runs beyond roughly half a metre, or a sealed recirculating bolt-on unit is preferred, cross to LSH; when the duty is light and the envelope cramped, LRM is the smaller step. Match the spare by roller diameter (1.5 mm) and roller count (6), verify the host set's row arrangement and grade (H from stock, P to order), and keep rails from different sets separate - accuracy is controlled only as a matched set. Allow time for dial-indicator alignment and pick the clearance method - adjusting screws, pressure plate or taper block - during design.
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 LGC1R6 FAQ
Six rollers per cage, each 1.5 mm in diameter. Size 1 ratings are 125 N dynamic and 120 N static, per roller. Rail length, row arrangement and accuracy grade are not carried on a cage code - they belong to the complete guide set it serves. Capacity scales with roller count, so no per-guide total is published; send your load details and we will advise.
No. It is the roller cage subassembly only - rollers in a cage, with no rails and no mounting hardware. It exists so a drifted or damaged cage in an existing size 1 guide can be replaced cheaply while the matched-set rails stay in place. Remember that LGC is non-recirculating: the cage travels with the slide by about half the stroke, so always verify stroke against the manufacturer's maximum-stroke table.
