About the AirTAC LRM15L
The AirTAC LRM15L is an LRM miniature linear guide: a 15 mm stainless steel rail with long blocks (16 mm assembled height, 32 mm block width). Each block is rated C 6.53 kN dynamic and C0 9.53 kN static, with allowable static moments MR 70.08, MP 63.69 and MY 63.69 N·m.
Blocks of different lengths share the same rail. A ball retainer keeps the balls in the block when it comes off the rail, so blocks are easy to swap; double-lip seals wipe the rail and keep dust out, and the end caps cover the screws and carry a seal plate against larger debris. The balls are ISO 3290 G10 grade. Rails are fixed with M3 bolts at 40 mm pitch and are made up to 990 mm in one piece. This page lists 63 stocked assemblies; preload: none, light, medium; accuracy: high, precision.

Choosing the Right LRM15L Configuration
Start with the rail length. The S value is the distance from the rail end to the first mounting hole: 4 mm minimum and 35 mm maximum on the 15 mm rail. If you need another length or end distance, request a quote.
Then choose how many blocks run on the rail: more blocks share the load and raise moment capacity.
Finally pick preload, accuracy and lock type. Preload A (none) runs most smoothly, B (light) suits high-accuracy work and C (medium) gives the most rigidity. Accuracy is H (high) or P (precision). A top-lock rail is bolted from above; T is a bottom-lock rail, bolted from below.
AirTAC LRM15L FAQ
A = no preload (radial clearance -2 to +3 µm), B = light (-7 to -2 µm), C = medium (-10 to -6 µm). More preload means a stiffer guide but slightly more running resistance.
A top-lock rail is bolted from above through the rail. A bottom-lock rail (T) is bolted from below, which suits mounting from underneath.
