Note)
1．※The hub and pressure flange for sizes within the standard stock shaft bore diameter range have pre-machined shaft bores for two-row type Power-Locks.
2．※The maximum shaft bore diameter includes a margin for a Power-Lock.
3．The maximum speed depends on the transmission capacity of the coupling. No balance adjustment has been conducted.
4．The weight, moment of inertia, and GD2 are given for the maximum bore diameter.
5．The allowable axial displacement is based on the assumption that the angular misalignment is 0.
6．Tsubaki can make sizes NEF45 or higher with a Power-Lock. Request drawings for more information.
7．Contact us to verify the strength when mounting on a hollow shaft.
