Airtac LGC Series Cross Roller Guide Rail LGC2A135R22-H
The AirTAC LGC Series Cross Roller Guide Rail LGC2A135R22-H is a crossed roller guide using Ø2.0 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 LGC2A135R22-H
Buyers arriving from ball guides should note something unusual about LGC2A135R22-H: the static rating sits slightly below the dynamic one, the opposite of the ball-guide habit of sizing on the larger static figure. The set itself is a three-row crossed roller guide with a 135 mm stainless steel rail and a cage of 22 rollers, 2.0 mm in diameter, at grade H. Crossed cylindrical rollers on hardened V-raceways give line contact and high rigidity, and because nothing recirculates, the rail length fixes how far the slide can go.
Per roller, the size 2 figures are 292 N dynamic and 290 N static; with 22 rollers in the cage, capacity scales with that count and no single per-guide total is published. As with every non-recirculating guide, the cage drifts along the rail by about half the stroke during motion, which is why the 135 mm rail must be chosen from the stroke table with the working stroke set short, and why cage drift is corrected simply by running several full strokes.

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.

Where the Airtac LGC Series Cross Roller Guide Rail LGC2A135R22-H Is Used
X-ray detector slide
Sliding a detector into and out of the beam path needs motion that is rigid, smooth and limited to a known stroke, which is precisely what a 135 mm non-recirculating rail provides.
Laser optics alignment carriage
Aligning a laser path on an optical bench involves small, critical adjustments; the crossed roller line contact keeps the carriage square under load.
Precision microscope stage
A measuring microscope stage moves a specimen in short calibrated increments; grade H accuracy plus careful fitting gives the repeatability the optics demand.
Is the Airtac LGC Series Cross Roller Guide Rail LGC2A135R22-H the Right Guide?
Size the duty honestly: crossed rollers reward short, stiff, high-accuracy strokes. If the application needs unlimited or long travel, or a sealed recirculating carriage that bolts on, LSH guides are the correct step; where the load is light and space minimal, LRM suits. Then confirm: complete guide versus cage spare; roller diameter and count together; row arrangement; rail length against the maximum-stroke table with margin; H (stocked) or P (order) accuracy; clearance taken up by adjusting screws, pressure plate or taper block; and time reserved for indicator-based fitting in the build.
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 LGC2A135R22-H FAQ
Size 2 means 2.0 mm rollers, rated 292 N dynamic and 290 N static per roller. The set is a 135 mm stainless steel rail in a three-row layout with a 22-roller cage, grade H accuracy. Because the ratings are quoted per roller, capacity scales with the roller count rather than appearing as one published guide total - send the load and duty to us for a proper sizing.
No. The 2.0 mm rollers sit in a cage and never recirculate, so travel is limited by the 135 mm rail and the cage itself moves about half the stroke with the slide. It is assembled and adjusted in place with a dial indicator rather than bolted on and forgotten - plan that fitting time into the build.
