What Are Slewing Bearings?
Slewing bearings, also known as slewing rings or turntable bearings, are large-sized bearings designed to support heavy axial, radial, and moment loads while enabling rotational movement. They are commonly used in equipment where large structures rotate or pivot smoothly and reliably.
Types of Slewing Bearings
-
Single Row Ball Slewing Bearings: Use a single row of balls to support combined loads, suitable for lighter applications with moderate rotational speeds.
-
Double Row Ball Slewing Bearings: Provide higher load capacity and better rigidity with two rows of balls, ideal for heavy machinery.
-
Four Point Contact Ball Slewing Bearings: Designed to carry axial loads in both directions, radial loads, and tilting moments with a single row of balls.
-
Cylindrical Roller Slewing Bearings: Use cylindrical rollers for higher radial load capacity, suitable for heavy-duty industrial equipment.
-
Tapered Roller Slewing Bearings: Offer excellent support for combined radial and axial loads, used in cranes and excavators.
Applications
Slewing bearings are widely used in:
Cranes and heavy lifting equipment
Wind turbines and solar trackers
Construction machinery such as excavators and bulldozers
Robotic arms and automation systems
Marine equipment and radar systems
