Advantages Of Case 350 Dozer Front Idler

High Hardness Alloy Material, Wear Rate Reduced By 50%

The special alloy steel with tensile strength of 750MPa is selected, and the surface hardness of the wheel body reaches HRC58-61 after twice quenching treatment.The wheel rim contact area adopts surfacing wear-resistant technology to form a 4mm hardened layer, the wear rate is only 50% of that of ordinary products under gravel conditions, and the service life is extended to more than 1500 hours.

Optimize The Structural Design And Increase The Load-Bearing By 25%

Through force simulation analysis, the spoke structure is improved, and the load-bearing capacity is increased from 6 tons to 7.5 tons under the condition of 10% weight reduction, which can easily cope with the working load of Case 350 bulldozer.Stiffening ribs are added at the connection between the wheel shaft and the wheel body, which improves the deformation resistance by 30% and avoids heavy load fracture.

Double Sealing Protection, Suitable For Multi-Environment Operation

The sealing combination of "double-lip fluororubber oil seal + labyrinth dust cover" is adopted, with the temperature range of -30 ℃ to 180 ℃ and the waterproof grade of IP 67.In muddy and dusty environments, the bearing failure rate is reduced by 70%, the maintenance cycle is extended to twice the original, and the equipment downtime is reduced.

Original Level Precision Manufacturing, Zero Obstacles To Installation

Relying on laser scanning technology to reproduce the original size, the tolerance of shaft hole is controlled within ± 0.012 mm, which is perfectly matched with Case 350 track frame.The installation does not need to be polished and adjusted, and the replacement can be completed in 20 minutes by a single person, thus reducing the labor cost.

The front guide wheel of Case 350 bulldozer is an important walking component specially designed for this type of equipment, which plays a key role in guiding the correct track of the track, balancing the weight of the body and buffering the impact of ground bumps.The overall structure is composed of wheel body, high-precision bearing group, sealing assembly and connecting shaft. The size parameters of each component are completely matched with the walking system of Case 350 bulldozer. It can be put into use without additional debugging after installation.

The wheel body is made of high-strength alloy steel through forging process, which effectively avoids the common defects such as air holes and sand holes in the casting, significantly improves the overall strength and toughness, and can easily cope with the huge pressure and the impact of complex terrain when the bulldozer is working under heavy load.After professional hardening treatment, the surface of the wheel rim has a hardness of HRC56-59 and excellent wear resistance, which can maintain a slow and uniform wear rate under harsh working conditions such as sand and hard soil, greatly prolong the service life and reduce the replacement frequency.

High-quality tapered roller bearings are used in the bearing group, which have the characteristics of strong bearing capacity and stable operation, and can well adapt to different working conditions of Case 350 bulldozer in various terrains.The bearing is filled with special grease with high temperature resistance and extreme pressure resistance, which ensures good lubrication effect in the temperature range of -25 ℃ to 110 ℃, reduces bearing wear and ensures flexible rotation of the guide wheel.

FAQ

Does this front idler fit all Case 350 dozer models?

Yes, the front idler of this Case 350 bulldozer is produced strictly according to the original full range of technical standards, whether your equipment is standard, long-arm or different years of Case 350 bulldozer, it can achieve precise adaptation, and there is no need to modify the equipment when installing.

How to judge that the front idler of Case 350 bulldozer needs to be replaced?

In case of these conditions, it is recommended to replace: the wheel body is seriously worn, and the rim thickness is reduced by more than 1/3 compared with the new part; there is obvious abnormal noise, jamming or shaking during rotation; the track deviates irregularly and other parts are excluded; the seal is damaged, resulting in oil leakage or impurities in the bearing.Under normal working conditions, it is recommended to check every 1000-1200 hours.

What are the precautions for installing the front idler by yourself?

Before installation, it is necessary to clean the silt and rust at the connection part, and check whether the shaft diameter is worn and deformed. During installation, it is necessary to ensure that the installation direction of the sealing element is correct, and the lip faces the inner side of the wheel body. The fastening bolts shall be tightened by several times according to the diagonal sequence, and the torque shall be controlled at 65-75 N ・ m. After installation, the guide wheel shall be rotated to confirm that there is no clamping stagnation or abnormal sound before putting into use.

What is the warranty period and scope of the product?

This product provides a 12-month warranty, which covers quality problems such as non-artificial cracking of the wheel body, early failure of the bearing, oil leakage of the seal, etc.If the above problems occur during the warranty period, they can be replaced free of charge with the purchase certificate, and the round-trip freight will be borne by us.Damage caused by human factors such as overload, collision and improper installation is not covered by the warranty.

What Our Clients Are Saying?

Master Liu

operator of earthwork team

The Adaptation Is Accurate, And The Machine Runs Much More Stably After Installation.

The auxiliary parts used before always make the track deviate. After changing the case 350 dozer front idler, the problem is completely solved.The wheels and tracks fit very well, and the machine works smoothly and noiselessly. After more than three months in the clay field, the rim wear is very slight, which is much more durable than I expected.

Boss Zhang

Head of Agriculture and Forestry Development Company

Excellent Wear-Resistant Performance, Agricultural And Forestry Operations Are Very Powerful

We use Case 350 to work in the woodland. There are many branches and stones, which cause great wear and tear on the guide wheel.This model has been used for almost five months, and the wheel body looks very good, and there is no abnormal noise in the rotation.Sealing is well done, there has been no leakage of mud and oil, much better than the cheap goods bought before, cost-effective.
