Abstract

The present invention is a magnetic seal for hermetic sealing large shafts (1) in apparatuses with through means. It comprises a casing (9), a bush (2) fixed to the shaft and bearing supports (3) of a floating sleeve (4) with a magnetic block, forming gaps (7) to be sealed with the bush and for the expansion gap with immovable solid surfaces and an anchoring screw (10) on its lateral surface, which catches the gear of the sleeve outside (4). The seal is characterized in that the supports (3) are of a pivoting type and the bearing flange of socket type. The bush (2) is made of magnetoconductive material and the upper portion of the floating sleeve (4) being fastened on the cantilever principle by the pivoting supports. The expansion gap is hermetically sealed between the lower portion of the floating sleeve (4) and the bearing flange walls and bottom within the apparatus throat (8) with a flexible annular crimp (17), placed between the lateral surfaces of the bearing flange and the magnetic block.
