Note)
1．Refer to the Table of Dimensions for long hub and extended-diameter hub dimensions. For long hubs, the overall length will be extended for as much as dimension B is lengthened.
2．The maximum speed depends on the transmission capacity of the coupling. No balance adjustment has been conducted.
3．The weight, moment of inertia, and GD2 are given for the maximum bore diameter (keyway) for a standard hub. For extended-diameter hubs and long hubs, add the value given in the Additional GD2 Table.
4．Tsubaki can make models with non-standard spacer lengths. Refer to the page for the Long Spacer Type.
5．The allowable axial displacement is based on the assumption that the angular misalignment is 0.
6．Check that the key surface pressure is in accordance with your operating conditions. The hub is made of S45C.
