Machines for the production of mineral wool fibres

The slewing bearing used in thermal insulation cotton production equipment is mounted at both ends of a large rotating drum. Since the overall load is moderate, medium- to large-sized single-row ball bearings are typically used. One bearing is connected to a gear driven by a motor. The axial movement generates radial torque, which causes the slewing bearing—and thus the drum—to rotate. The bearing on the opposite end serves as a support, maintaining smooth rotational motion.

This setup ensures the stable and uniform operation of the equipment, which is essential for evenly distributing and forming thermal insulation cotton with consistent quality.
