Rotary bearing for Blender

The slewing bearing plays a crucial role in the structure of an industrial blender or mixer used to combine cement, sand, dry powder mixtures, and other materials. The main component is a shaft with blades that rotates within a drum or tank, blending raw materials into a homogeneous mixture.

The slewing bearing connects the mixing shaft to the drive system and ensures stable rotation. A motor drives the gear, creating radial torque via axial movement that turns the slewing bearing and, consequently, the shaft. Although the axial and radial forces are moderate, mixers operate in dusty, humid, and vibration-prone environments. Therefore, a bearing with excellent sealing performance, impact resistance, and robust axial and radial support is essential for reliable operation and longevity.
