Excavator Slewing Bearing

Excavator Slewing Bearing

The excavator slew bearing plays a crucial role in the machine’s performance. It enables the excavator to rotate and turn 360 degrees without changing its position. It can also handle a wide range of load combinations, including thrust, radial, and tilting moment loads.

The raceway on a slewing bearing can deform after a long period of use. This is a common issue that affects slewing bearings used in excavators and other heavy machinery. This can result in slewing bearing failure and a loss of productivity for an excavator.

Excavator slewing bearing is critical components in large-scale construction equipment, such as tractors and excavators. They can support heavy weights and complex loads, which makes them an important part of a range of applications from military to commercial machines.

The excavator slewing ring bearing is one of the essential parts in the excavator aftermarket; we provide the same quality products as OEM. Our excavator swing bearings have been sold to East Asia, South Asia, the Middle East, South America, and Europe. In addition to the ordinary rotary excavators that most companies can produce, we often develop new rotary rings for excavators based on old sample measurements.

Maintenance of Excavator Slewing Bearing:

An excavator slewing bearing is the transmission element between two relatively rotating parts on the excavator. It can realize the slewing motion of the two parts, and also bear the axial load, radial load, and tilting moment of the excavator.

The slewing bearing has rolling elements, raceways, and spacers inside, which are separated by oil seals. The slewing bearing is easily damaged and failure occurs relatively frequently.

As an important component of an excavator, the slewing bearing needs to be maintained. It should be lubricated with heavy-duty grease at regular intervals as recommended by the manufacturer.

Slewing Bearing Application:

Slewing bearings are extensively applied in metallurgy, vessel, oil, chemistry, mining, coal, hydroelectric power, port machinery, heavy machinery, and aerospace or other fields.

Mine machines, port hoisting machines, port oil transfer equipment, onshore and offshore cranes, excavators, concrete machines, paper machines, plastic and rubber machine, weave machines, steel plants, electronic power plants, wind power generators, other construction, and industry machines or equipment.
