ALUMINUM RIGID RAIL
ALUMINUM RIGID RAIL is a high quality alloy, rigid section made to the machine tool tolerance shown in
the sectional view below. The carriage drive pinion meshes with a machined gear rack that is mounted on
the rail. The wheels of the carriage travel in opposed grooves at either side of the rail, locking the carriage
to the rail. Heavy duty [H.D.] aluminum four-legged rigid rail is supplied in two lengths: ARR-1080 [93-1/2"
(2.37 m)] called 8' (2.37 m) rail and ARR-1085 [46-1/2" (1.18 m)] called 4' (1.18 m) rail - see insert below.
Extra heavy duty aluminum four-legged rigid rail: ARR-1250 [93-1/2' (2-37 m)] called 8' (2.37 m) rail and
ARR-1200 [46-1/2" (1.18 m)] called 4' (1.18 m) rail, is also available.
NOTE: 8' Rails accept up to 8 supports, 4' Rails accept up to 4 supports.
RAIL FOR LONGER SPANS:
When unsupported rail paths longer than 93-1/2" (2.37 m) nominal 8' (2.37 m) rail are required, multiple
sections of standard rail are mounted on plate, channel or box sections.
