A slewing bearing, also known as a slew ring, is a kind of huge-size rolling bearing that can make the best use of its design in favor of facilitating oscillatory movements. It is usually comprised of two rings, an inner ring and an outer one, both or one of which are equipped with gear teeth. What makes power transmission perfect among them is those holes used for fastening purposes on both rings. Thus configured, this type of bearings act singly or in combination under various loads capacities while capable to bear axially and radially at the same time tilting moments generated thereby.

Slewing bearings were invented over 40 years ago but they took some time to become popular worldwide as components widely applied in machines throughout many industries within mechanical engineering; nevertheless it was China where such products started being mass-produced following introduction into Rothe Erde company’s design and technological know-how from former West Germany during early eighties’ last century. This was a major breakthrough point leading towards higher efficiency levels achieved by machine elements used across different branches.

SKF brand – one among most famous manufacturers operating today – has developed its own lineups consisting various types suitable for particular tasks like turrets moorings systems or cranes employed at offshore oilfields extraction sites. Working out those solutions required special sealing arrangements together with considerable application experience so that these items could deliver good performance even under severe environmental conditions; moreover there were proposals made by SKF engineers themselves concerning fully-customized monitors integrated into advanced lubrication/sealing systems which would help prolonging service life alongside improving operational characteristics through optimization measures taken into account during design phase itself. Furthermore being present globally enabled them not only offer their clients all needed products but also provide necessary services wherever required thus contributing greatly towards reducing expenses related with downtime occurrence besides increasing overall work efficiency levels worldwide too.
