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.
