ABSTRACT:
A locating arrangement for a shaft rotatable in a bore of a support includes a first annular locating element radially interposed between the support and the shaft. Two annular surfaces of the element are axially offset in opposite directions from the orifice of a supply conduit for pressure fluid in the bore of the support and formed with respective pairs of grooves arcuate about the axis of rotation, the grooves of each pair being adjacent and remote from the orifice respectively and bounded by lands of the associated surfaces. Ducts connect each adjacent groove to an axially offset remote groove. A second annular locating element has two face portions associated in parallel relationship with the afore-mentioned lands of respective surfaces and defining throttling gaps with the associated surfaces which communicate with the orifice of the supply conduit. The locating elements are respectively secured to the shaft and support and keep the shaft floating in the bore of the support in the presence of pressure fluid in a precisely defined position.
