Notes

1. Shaft misalignments:
    Angular 5 degrees
    Parallel offset 0.25 mm (0.50 mm T.I.R.)
    Axial motion + .25 mm.

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: 17-4PH high-strength stainless steel.

    Finish: natural

4. Manufacturing dimensional tolerances unless otherwise specified are:
    x + .5 mm
    x.x + .25 mm

5. Click Here for other available bore dimensions.

6. Inertia is based on smallest standard bore diameter.

7. Keyways available on the 40mm and 50mm OD only.
