Front Idler PC20-3

Front Idler PC20-3

The front idler is used to guide the track to rotate correctly to prevent its deviation and derailment.

 Most excavators also act as supporting wheels. This can increase the contact area between the track and the ground and reduce the grounding voltage.            

The wheel surface of the front idler is made into a smooth surface, and the middle arm ring acts as the guide, while the torus on both sides supports the rail chain.            

The smaller the distance between the guide wheel and the nearest supporting wheel, the better the guidance.            

Material: 40, 50 mn steel, casting, tempering, hardness HB230-270           

Main points:           

In order to make the guide wheel work and prolong its life, the radial runout of the wheel face on the central hole should be less than or equal to 3MM, and the correct alignment should be made when the wheel is installed.

Product advantages

Each mini shovel front idler is produced using dished out quality steel plates of generous thickness for maximum strength. An abundance of internal reinforcements sage guard shape is against twist from severe usage such as ripping.

Brackets

brackets of mini shovel front idler are made by ductile iron. It shows exceptional resisitance to shock.

Bimetal bushing

Bimetal bushing of our mini shovel 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.

The design of double-cone sealing and lubrication for life makes the carrier roller have long life time and perfect performance under any working condition.

Precision care

Each front idler is precision machined to house special high impact low wear bimetallic bushings.

Factory Advantages:

1). Materials
Our company purchases steel from some large steel groups, such as Shanghai Baoshan Steel Mill, Beijing ShouGang Group, Hangzhou Steel Mill, who provide steel with not only good mechanical properties but stability of chemical component to make sure of the high strength of parts.
2). Manufacture Procession
First, we have already owned High-precision Digital Machining Center for mould making in special Mould Workshop, which decides the high quality of mould. 
Second, heat treatment is utilized. We adopt the Controlled-atmosphere Automatic Heat Treatment Furnace to guarantee the good quality and stability of our parts.
3). The total quality control system
We have established a total quality control system which means we perform quality control from buying raw materials to different machining procession and to final packing. We have many high-tech testing instruments, such as Torsion Tester, Peel Force Tester and Metallographic Microscope and etc. which determine the excellent quality and appearance of our products.
