- The applicable shaft diameter is φ2 to φ4 mm.
- The recommended shaft tolerance is h6.
- The allowable radial direction displacement represents the case, eccentricity and tilt angle are zero.
- The eccentricity and tilt angle act simultaneously, the allowable tilt angle is restricted.
- The moment of inertia and mass are shown for the maximum shaft hole diameter.
- Please insert the shaft all the way to the bottom of the hub (up to 3.5 mm) securely.
- The maximum rotational speed does not consider dynamic balance.
- You need a standard shaft diameter other than φ2, φ3, or φ4, please contact us separately.
- This is a made-to-order product.
