Where Is Liugong Excavator slewing bearing Used?

Wherever a Liugong equipment swings its boom, digs, or unloads, a Liugong Excavator slewing bearing is at work. Replacement Bearings: Luoyang Heng Guan Bearing Technology Co., Ltd. provides replacement bearings for the CLG906 through CLG936D series. This guide describes the location of the bearing, its rotation, the loads it bears, and its relation to mining crane bearings.

Where Is the Liugong Excavator Slewing Bearing Installed in the Machine?

The slewing bearing of the Liugong Excavator is located between the top framework and the undercarriage. The cab, boom, engine, and hydraulics are carried on an upper frame with a single ring fastened to it. The other ring is attached to the lower carriage, and a gear incorporated therewith meshes with the pinion of the swing motor.

Position and Function in the Machine

Sizes and Installation Points

In our program, Heng Guan Bearing manufactures rings for tiny 6-ton machines and up to big versions with a weight of 30 tons and diameters of up to 10,000 mm. This is the heart of the machine, and the quality of installation counts. Proper bolt tightening, clean and level mounting surfaces, and greasing the grease channels before operation provide smooth, lasting service.

Many consumers also connect it with mining crane bearings with a similar mounting approach. Now, let’s see how the rotation works.

How Does a Slewing Bearing Support 360-Degree Excavator Rotation?

Between the two rings, there are hardened raceways that allow steel balls or cylindrical rollers to run, which allows for continuous rotation. The hydraulic swing motor moves the pinion, which rotates the bearing gear smoothly to move the top structure. This allows the operator to dig and unload without moving the rails.

Structure Options

A typical Liugong Excavator slewing bearing is a single-row, four-point-contact ball bearing, compact in height, and can withstand many force directions with minimal running noise. Larger machines may be of cross roller or double row configurations, and severe load duty cycles may need three-row roller designs.

Technical Parameters

Below is the standard specification of our slewing bearings for excavators. Dimensions, hole patterns, and tooth counts are matched to your model or sketch

Heng Guan Bearing provides P0, P6, P5, and P4 accuracy levels and excellent seals that block out dust and water. The same considerations apply to mining crane bearings where dependability is just as important. Discuss with our experts to establish the correct kind for your equipment.

What Loads Must Liugong Excavator Slewing Bearings Withstand in Heavy-Duty Operations?

During daily digging, a Liugong Excavator slewing bearing carries axial load from machine weight, radial load as the boom swings, and overturning moment when the bucket is extended.

Load Types and Bearing Response

Engineering Behind the Load Capacity

Heng Guan Bearing employs high-quality alloy steel, finite element analysis, and reinforced raceway design so the bearing can take these combined forces with a substantial safety margin. The raceways are induction hardened, and the gear teeth are hardened to withstand shock and bending loads. Our goods are manufactured to ISO, DIN, and GB standards. In quarries and mines, the same engineering supports mining crane bearings that spin under strong, repetitive shock loads.

Applications of Mining Crane Bearings in Excavators and Heavy Mining Equipment

Mining crane bearings and the Liugong Excavator slewing bearing are used in many of the same machinery, besides construction sites: mining excavators, crawler cranes, port cranes, and loaders. Both rely on large-diameter slewing rings that revolve with big payloads in dirty and harsh environments.
