Although Omega couplings can withstand gross misalignment, care should be taken for best possible alignment to assure optimum performance. The
caliper/straightedge alignment procedure is described below. If greater alignment accuracy is desired, a dial indicator method is recommended. There are occasions
when equipment manufacturers requi
re more specific alignment tolerances, in which case, the manufacturer's recommendations should be followed.
1. To correct for angular misalignment, use calipers to check the gap between hubs. Adjust or shim equipment until the gap is the same at all points around the
hubs.
2. To correct parallel offset, place a straightedge across the huh flanges in two places at 90" to each other. Adjust or shim equipment until the straightedge lays
flat on both sides.
3. Tighten down connected equipment and recheck a
lignment.
4. Install elastomer element, tightening all cap screws to the values shown in Table 1 as described on the reverse side.
5. If practical, recheck and tighten cap screws after several hours of operation.
