What the LXMMCRSEA03S100 actually is
The LXMMCRSEA03S100 is a guide rail set, not a drive — it carries the Lexium MC12 multi carrier in a straight installation, and the listed code is filed as a spare-part accessory for that multi-axis carrier system rather than as a drive module itself. For a storeroom buyer that distinction matters: this is the consumable strip the multi carrier rides on, sourced against the same Lexium MC12 BOM line whenever the rail is replaced during a rebuild.
Dimensions and the 0.5 unity of length
The rail measures 150 mm long, 35 mm wide, and 8 mm deep, which matches the 0.5 unity-of-length increment called out in the description and lets two rails be butted end-to-end to span a 1.0 unity carrier without re-machining. Installation direction is straight, so the rail is laid parallel to the carrier travel axis — a field tech swapping a worn strip only needs to confirm the carrier carriage is parked before sliding the new set into the mounting channel.
