Orientation flat key structure
The sliding key structure
Feather key ——Keys motionless,
wheel hub axial movement
The sliding key ——Key
moves along with the wheel hub Features: convenient installation and impact on the parts for neutral, easy manufacturing, reliable function, used for high precision coupling.But only circumferential fixation, unable to bear axial force
