What is a Slewing bearing?

Slewing bearings are specialized bearings that allow rotational motion while supporting large loads. They are used in applications where rotation is required, such as cranes, wind turbines, and movable machinery. Unlike standard ball or roller bearings, slewing bearings are designed to handle significant torque and weight, ensuring smooth and precise movement over a wide rotational range.

A slewing bearing typically consists of an inner and outer ring, with either balls or rollers arranged between them. This design allows it to endure high loads while providing stable rotation. These bearings are capable of handling heavy-duty applications where precise and reliable movement is crucial, such as in large machinery, wind turbines, and communication satellites.

Features:
・High load capacity
・Precision rotational control
・Suitable for large machinery and equipment
・High durability

Application of Slewing bearing

１．Cranes: Used in the rotating part to support large loads while enabling rotation.
２．Wind turbines: Positioned between the turbine blades and the shaft to allow rotation based on wind direction.
３．Mobile machinery: Used in construction machines and excavators requiring rotational movement.
４．Communication satellites: Used to control the rotation of antennas.
５．Ship steering mechanisms: Used in rudders and other rotating parts to steer ships.
