Product introduction

The working principle of the guide wheel assembly is as follows: the oil is injected into the cylinder through the oil nozzle with a grease gun, so that the piston extends outward to push the tension spring, so that the guide wheel moves left to tighten the track, and the tightening spring has a proper stroke, when the tension force is too large, the spring is compressed to cushion; when the excessive tension force disappears, it is compressed. The spring pushes the guide wheel in situ, which ensures sliding along the crawler rack to change the wheelbase, ensures the disassembly and assembly of the crawler, reduces the impact of the walking process, and avoids derailment of the track chain.

Advantages

Brackets

brackets of idler roller are made by ductile iron. It shows exceptional resisitance to shock.

Bimetal bushing

Bimetal bushing of our front idler is based on steel plate which special alloy is sintered on it. It shows high loading ability and high ability of fatigue resistance.

Cost saving service life

The heavy profiles of idler roller rims are carefully heat treated in depth for extra service life.

Floating seal group

Floating seal group of our of idler group 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 idler assy 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.

Our idler for bulldozer are applicable to below models:

Attentions while assembling the rollers

1. Before assembling rollers,smooth the sharp part of sapre parts and do the deburring,clean the inner holes of the roller body and oil seal etc..

2. Do not break and scratch any part of the sealing parts.

3. Do not oil and distort the rubber floating seal ring during assembling the rollers.

4. A small amount of oil should be covered on the contacting surface while fitting the floating seal group.

5. After finishing the assembling process,fill clean extreme-pressure vehicle gear oil to take 80 percent of the inner cavity of roller body and do the running test then confirm no leakage after 4 hours.
