<p>The plain bearing sleeve is used for the shaft of circulation pumps for heating and water supply system. This bearing which is lubricated by the liquid to be pumped. This bearing is insensitive to the dirt and to the lime or salt depositions from the liquid to be pumped. The bearing is noiseless and has long life. The end faces of the plain bearing sleeve (9) have grooves (11) interrupting the contact face (16). The grooves which project axially into the load bearing area, start from each end are diametrically opposite but their axial lengths overlap. The grooves can also be helical.</p> |
