What are the sizes of the turntable bearings?

Turntable bearings, also known as slewing bearings or slewing rings, come in a variety of sizes to accommodate different applications and load capacities. The size of a turntable bearing is typically defined by its outer diameter, inner diameter, and overall dimensions. These bearings are commonly used in various industries, including construction, mining, material handling, and robotics, to allow rotational movement between components. Turntable bearing sizes can range from small bearings used in lightweight applications to large bearings designed for heavy-duty industrial use. 

Turntable bearing sizes

Small to Medium Sizes

Outer Diameter: 100 mm - 600 mm

Inner Diameter: 50 mm - 400 mm

Medium to Large Sizes

Outer Diameter: 600 mm - 1500 mm

Inner Diameter: 400 mm - 1200 mm

Large Sizes

Outer Diameter: 1500 mm - 6000 mm

Inner Diameter: 1200 mm - 4500 mm

Extra-Large Sizes (used in specialized applications)

Outer Diameter: 6000 mm and above

Inner Diameter: 4500 mm and above

These sizes are approximate ranges and can vary depending on the manufacturer, the specific design of the turntable bearing, and the intended application. When selecting a turntable bearing size, factors such as load capacity, rotational speed, mounting space, and the specific requirements of the application need to be considered.

It's important to consult the manufacturer's specifications and guidelines when choosing a turntable bearing for your application. Turntable bearings are critical components, and selecting the appropriate size is crucial to ensure proper functionality, longevity, and safety in various industrial and mechanical systems.
