ALUMINUM RIGID RAIL / “ARR”
ALUMINUM RIGID RAIL is a rigid channel section made of high quality alloy
to machine tool tolerance as in the sectional view shown below. A machined
gear rack is mounted on the rail, with which the drive pinion of the carriage
meshes. 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.
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, I-beam, channel or box sections.
