How to prolong the service life of slewing ring bearings | TFL

Construction: The construction industry benefits from slewing bearings, especially in load-bearing and lifting appliions, such as lifts, cranes, hydraulic excavators, and drilling machines. Bottling technology: The 360-degree rotation of the slewing ring makes it particularly suitable for industrial bottling appliions, including sterilization, rinsing, capping, and labelling functions.
