Excavator

Excavator is usually using internal quenched gear single row four-point contact ball slewing bearing. This type of slewing bearing can bear axial load, radial load and tilting moment and can withstand large impact. Rotation is flexible and stable.

Port crane

Three row roller slewing bearing can bear different loads simultaneously. The capacity load is the largest one comparing with other type slewing bearing. Due to the large axial and radial dimension & solid structure, it is especially suitable for heavy-duty machinery, such as harbor crane,ship crane, etc.

Truck crane

Truck mounted crane is usually using small external gear single row four-point contact ball slewing bearing which is with compact structure . This type of slewing bearing can bear axial load, radial load and tilting moment simultaneously.

Aerial platform vehicles

Aerial platform vehicles usually uses single row four point contact ball slewing bearing which is designed in compact structure. This type slewing bearing can bear axial force, radial force and tilting moment at the same time, which is widely used in small and medium-sized construction machinery.

Ferris wheel

Ferris wheel usually uses double row ball slewing bearing. There are two rows of rolling element, which can bear larger axial load, radial load and tilting moment. It rotates flexibly and stably with higher safety factor.
