Notes
1. Shaft misalignments:
Angular 5 degrees
Parallel Offset .010 in. (.020 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 used for ACR / AR series.
Finish: clear anodize
4. Metric fasteners available on request.
5. Manufacturing dimensional tolerances unless otherwise
specified are:
fraction + 1/64
x.xx + .01
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.
