Abstract
A scroll-type fluid machine has a drive scroll which is rotatably supported by a novel bearing arrangement. The bearing arrangement includes a bearing housing which is detachably mounted on a casing of the fluid machine. A journal bearing which rotatably supports a drive shaft of the drive scroll is secured inside the bearing housing. An oil seal surrounds the drive shaft beneath the bearing, and grease fills the space between the bearing and the oil seal.
