Bulldozer Track Roller D60

Production:

self-lubricating bulldozer track roller d60

Composition:

Track roller body, shaft, bimetal bshing,floating seal group,collar and other related components c. Track rollers can be divided into single flange type and double flange types; and rollers for excavators  are generally black paint, and bulldozer ones are generally yellow paint.

 

bulldozer lower roller body materials generally 50Mn, 40Mn2, and other materials, the main process of casting or forging, mechanical processing, and then heat treatment, the hardness of the wheel surface quenched to reach HRC52 ~ 58, in order to increase the wear resistance of the wheel surface. The processing accuracy of the supporting wheel axle is required to be high. Generally, NC machine tools are needed to process the axle to meet the requirements. There are more 40Mn2 materials, and quenching and heat treatment should be carried out after processing. The hardness reaches HRC42 or so.

 

Our advantages of bulldozer track roller d60s are as below:

 

Bimetal bushing

Bimetal bushing of our bulldozer lower roller d60 is based on steel plate which special alloy is sintered on it. It shows high loading ability and high ability of fatigue resistance.

 

Floating seal group

Floating seal group of our single flange bulldozer bottom roller d60 has super seal performance under bad working conditions like being muddy or steamy etc.. it is applicable for the condition of low speed and heavy load. And it is anti-friction and can be auto-compensated after wearing.

 

Lubrication oil

Lubrication oil of our single flange bulldozer down roller d60 is selected carefully. It can lubricate shaft and bushing well to lower the wearing utmostly. And it can cool the roller perfectly. Those maximize the inner structure life.
