Notes
1. Shaft misalignments:
Angular 5 degrees
Parallel Offset .030 in. (.060 in. T.I.R.)
Axial Motion + .010 in.
2. Dynamic torque ratings are momentary values. For non-reversing
applications, divide by 2. Divide by 4 for reversing applications. Should the
torque ratings be marginal for your application, contact us
for analysis.
3. Material : 7075-T6 aluminum alloy
Finish: clear anodize
or Material: 17-4 PH high-strength stainless steel.
Finish: natural
4. Metric fasteners available on
request.
5. Manufacturing dimensional tolerances unless otherwise specified are:
fraction +1/64
x.xx +.01 in.
6. Click Here for other available bore dimensions.
7. Inertia is based on smallest standard bore
diameter.
8. With integral clamp attachments only, this bore size requires an
operating clearance diameter greater than coupling outside diameter.
9. Inch and metric keyways available.
