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
or Material 17-4 PH high-strength stainless steel used for HCR / HR series.
Finish: natural
4. Metric fasteners available on request.
5. Manufacturing dimensional tolerances unless otherwise specified are:
fraction + 1/64
x.xx + .01
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.
