Slewing Bearing

A slewing bearing, also known as a slew ring, is a large, ring-shaped bearing used to support and facilitate the rotation of heavy machinery or structures, such as cranes, excavators, and wind turbines. It consists of an inner and outer ring, with rolling elements (balls or rollers) placed between them, allowing smooth, low-friction rotation. Slewing bearings are designed to handle high radial, axial, and moment loads, making them ideal for applications where precise and reliable rotation is required. They are essential for rotating heavy equipment with stability and precision, ensuring long-lasting performance in demanding conditions.
