PURPOSE: A hub bearing and a shaft device of an integrated axle suspension for a vehicle are provided to reduce the weight and size of the hub bearing by assembling a shaft without using components, such as shaft bolts. CONSTITUTION: A hub bearing and a shaft device of an integrated axle suspension for a vehicle comprise a shaft(13), an axle housing, a hub bearing(12), bearing assembling bolts(14), hub bolts(17), a bearing cap(15), and an oil seal. The shaft is connected to a differential gear. The axle housing surrounds the shaft. The hub bearing is formed by integrating a hub and a bearing and is installed in the end of the axle housing. The bearing assembling bolts fix the axle housing to the hub bearing. The hub bolts are installed in the hub bearing. The bearing cap is installed in the end of the hub bearing. The oil seal is formed in the hub bearing and prevents oil leakage.
