A slewing ring, also known as a Slewing Bearing or turntable bearing, is a rotational rolling-element bearing that supports axial, radial, and moment loads. It is typically used in rotating machinery, such as cranes, excavators, wind turbines, and other applications that require smooth, low-friction rotational movement.
Slewing rings consist of an inner and outer ring, a set of rolling elements (such as balls or rollers), and a cage that holds the rolling elements in place. The inner ring is usually attached to a stationary component, while the outer ring is connected to the rotating component. The rolling elements provide support and enable smooth rotation between the inner and outer rings.
Slewing rings can handle high loads and are designed to withstand heavy-duty and high-precision applications. They are often used in situations where large axial or radial loads, tilting moments, or combination loads are present. The design and construction of slewing rings vary depending on the specific application requirements.
Overall, slewing rings play a crucial role in enabling smooth and controlled rotation in various industrial and mechanical systems.
Here are some key points about slewing rings:
A slewing ring is a large rolling element bearing that can accommodate high loads and rotational motion between two parts.
It typically consists of an inner ring, an outer ring, rolling elements (balls or rollers), and often has internal gears.
The gearing allows the slewing ring to precisely index positions.
Common applications include excavators, cranes, pans & tilts, solar panels, wind turbines, tunnel boring machines.
Slewing rings are also sometimes referred to as slew bearings or turntable bearings.
They can handle axial, radial and moment loads all in one bearing.
Slewing rings range in size from 4 inches to 39 feet in diameter.
They are defined by bore diameter, outside diameter, gearing design, sealing, lubrication method, mounting configuration.
Materials used include steel, stainless steel, brass, aluminum, plastic.
Advantages over plain bearings are lower friction, high load capacity, resistance to shock loads.
In summary, a slewing ring is a heavy-duty rolling element bearing that provides precise rotational capability under high loads, making them ideal for rotating large structures across diverse industries. The integrated gearing, sealing and lubrication customize them for their operating environment.
