Customized Excavator Friction Welding Track Roller Bottom Roller Repair For KOMATSU PC200

Product Basic Information

Friction Welding Roller

The track roller has two kinds of welding methods, one is traditional and the other is friction-welding.

Friction welding is a solid-state joining process, which could achieve reliable solder joints

and create high-quality, high-strength joints with low distortion.

Differences between Friction-welding and Traditional Rollers

1.Friction-welding track roller is better in the wear-resistance and has a longer working lifetime.

2.Consumption of raw material: the roller bodies of traditional track roller are connected

by the welding rod. but the friction ones are connected by the friction between rollers' bodies.

So the friction-welding roller will be added more raw material to make sure the roller is perfect to

the standard size after welding.

3.Inner parts: For the traditional rollers, the welding is done after two processes of machining,

so the size of the inner parts is not so precise as friction-welding ones. For the friction-welding ones,

after the welding, there is one more precise machining with concentric loCATEEEEEEEEEEing to make sure

the conformity of inner size, this means the inner parts are more precise with a higher standard.

Advantages / Features:

Undercarriage is adopting through hardening system and spraying quenching system while complying with

the stringent ISO System.

We are able to assure the part has excellent wear resistance even in the most severe working conditions.

We are using advance machining centre,horizontal and vertical CNC machining to execute processes such as machining,

drilling, threading and milling to ensure the qulity and precision of each component to ensure the accuracy of assembly dimensions.

This is to maximize the life span of each component and minimize production cost per hour.

We can be use for different excavator PARTS (more than these)

We Can Provide Other Excavator Items
