BD155-6A bearings is special use in excavator bearings, its inner diamater 155mm, outer diameter 198mm, so we also called DAC155198, The materials we adopt high quality chrome steel GRC-15 materials, G10 grade steel balls and robust press steel cage, BD155-6A bearing have the same internal structure with angular contact ball bearings, the angular contact is 30 degree.

Excavator bearings include: Crawler excavator travel bearings, excavator slewing bearings, excavator needle roller bearings, excavator gearbox bearings, excavator travel motor bearings, excavator travel drive bearings, excavator joint bearings or excavator spherical plain bearing, excavator slewing bearings and Inch non-standard bearings used on excavators

Despite facing harsh operating conditions, crawler excavators must operate profitably in construction projects. They are required to move more materials with greater speed and reliability, suffer less downtime and use fuel more efficiently. Choosing components and services that raise efficiency, maintain uptime and reduce environmental impact is crucial.

The installation and disassembly method of the excavator bearing should be determined according to the structure, size, and matching nature of the excavator bearing components. The pressure of installation and disassembly should be directly applied to the end surface of the tightly fitted excavator bearing retainer ring, and the pressure cannot be transmitted through the excavator bearing rolling elements, because this will cause indentation on the working surface of the excavator bearing and affect the normal operation of the excavator bearing. It may even damage the bearings of the excavator. The retainer, seal ring, dust cover and other parts of the excavator bearing are easily deformed, and the pressure for installing or disassembling the excavator bearing cannot be added to these parts.

We not only produce BD155-6A (DAC155198), But also the other bearings for Excavator machinery

1. Special Angular contact ball bearing for Excavator

2. Tapered Roller Bearings ( inch & metric, paired)

3. Cylindrical roller Bearings

4. Spherical Roller Bearings

5. Spherical Plain Bearings

6. Slewing Bearings

An example of how this is achieved is the use of automatic lubrication systems. These perform a critical operation with essentially no human intervention. As well as streamlining and improving the process of lubrication, it leaves staff free to concentrate on other tasks. In some instances, it’s possible to avoid re-lubrication completely, with sealed bearings that are lubricated for life, like for example, our Explorer plain bearings.

Crawler Excavators Also have many kinds of design according to the special situations

-- Standard Crawler Excavators

-- Intelligent Machine Control

-- Hybrid Crawler Excavators

-- Short Tail Swing Crawler Excavators

-- Demolition Crawler Excavators

-- Super long Front Crawler Excavators

Our Bearings Mainly used for KOBELCO excavator, KOMATSU excavator, CATERPILLAR excavator, KATO excavator, HITACHI excavator, DAEWOO excavator, HYUNDAI excavator, Volvo excavator, etc.

Quiet, safe and reliable. The environmentally friendly crawler excavators are also simple to operate and probably the most efficient around. It’s no wonder they’re among the top selling hydraulic excavators in the world.
