Another important thing to consider is minimum hub thickness, which is calculated based on such factors as locking device outer diameter and surface pressure. The hub should be thicker than this value to prevent excess stress and early failure. Locking device manufacturers typically provide this formula.Andrew/Whittet-Higgins: Consider all costs of the assembly rather than the individual costs of each component.Keith/U.S. Tsubaki: Go keyless. Keys and splines weaken the shaft by cutting into it, requiring a larger shaft and accompanying parts, such as bearings, to handle the higher forces.End-user adviceWhat AirTollAccessory should END USERS do to maximize life and productivity?Carl/Ringfeder: Pay close attention to the OEM''s service instructions AirTollAccessory and use the locking device manufacturer''s technical information to help with replacement or reinstallation. Warren/Fenner: In general, locking devices don''t require any maintenance or special attention to maintain their performance and maximum life.
