Power-Lock AS Series Major Specifications

Package

Applicable shaft tolerance	Applicable hub hole tolerance	Applicable surface roughness	Centering function	Lubrication during assembly	Hub movement during assembly
h8	H8	Ra1.6	NO	Required	NO

This Series requires a centering guide for the hub.
If the length of the guide portion for centering is at least half that of the shaft diameter (d/2), you can obtain practical centering accuracy.
Determine the tolerance of the guide portion based on the required precision.
