The A-750W is built for tight spaces and ANSI-style pumps — a design that adapts to most smaller equipment, with three different radius surfaces for indicator readings. It fits shafts or hubs up to 2.8" and expands to 9" — the bracket assembly rotates with as little as 3" of shaft-to-base clearance. ½" thick.
Like every ALINE set, the A-750W uses the reverse-indicator method: no batteries, no calibration, nothing to charge or reset between jobs. Set the brackets, turn the shafts, read the dials.
Each set ships with Starrett 196B1 dial indicators, accurate to .001" — tight enough for the tolerances referenced in API 686 and ANSI S2.75, the standards most plants and contract alignment jobs are already specifying work to.
Any millwright can learn the procedure in a single shift. Built for the close-clearance jobs a bigger set can't physically get into — indicators already in the case.
