Extreme heat and dust make the highest demands on slewing rings.
Quality and service life really count here.


IMO inside


IMO slewing rings are used as customized sturdy solutions, mounted to be impact-resistant and vibration-resistant in use. Temperature-resistant seals and greases defy the high temperatures while specially produced shielding plates keep dirt and coarse particles away.

Since unplanned interruptions and failures cause serious complications for all types of industrial furnaces, ladle turrets, continuous casting systems, etc., the quality of the installed components is important. IMO products ensure the highest levels of reliability.

Ladle turrets

Three-row roller bearings enable the loading and unloading of ladles with molten steel. The high moment loads here result in extreme impact loads.  

Electric arc furnaces

3-row roller slewing rings are installed in the cover swing gear mechanisms of electric arc furnaces.

Cranes in smelting works and foundries

Single-row ball slewing rings are used in loading cranes, traverse overhead slewing cranes and console slewing cranes. 

Forging manipulators

Forging manipulators, which transport the workpieces between the heating furnace and the forge, are equipped with single row ball slewing rings with internal gears.

Continuous casting plant

Rolling performance and service life are the most important features for continuous casting plant, so that 3-row roller slewing rings are usually used here.
