D60A-8 Bulldozer Lower Roller
Production Description
A Komatsu bulldozer lower roller is a vital component of a bulldozer's undercarriage system. It is positioned at the bottom of the equipment and is responsible for supporting the weight and ensuring smooth movement of the bulldozer.
The lower roller is comprised of a steel shell and an inner bearing which rotates on an axle. It is also equipped with precision seals and lubrication to prevent dirt and water from entering the roller.
The Komatsu bulldozer lower roller is designed to withstand harsh conditions and long-term usage. It is made of high-quality materials that ensure durability and longevity. It also reduces uneven wear and tear on the machine's tracks, which is important for long-term performance.
Advantages Of Upper Roller
1 .The design of double-cone sealing and lubrication for life makes the bulldozer lower roller have long life time and perfect performance under any working condition.
2. Bimetal bushing of our bulldozer track roller is based on steel plate which special alloy is sintered on it. It shows high loading ability and high ability of fatigue resistance.
3. Each track roller shell is carefully heat treated to ensure long wear life and stress resistance.
4. Differential type of quenching or through type of quenching heattreatment can ensure certain heat treatment hardness depth and so give good anti-cracking effects.
5. Warm forging treated roller shell gains distinguishing inner material fiber flow distribution architecture.
6.Each lower rollers shaft is machined by the utilization of the most modern technological advances known to the industry, Grinding and finishing methods ensure mirror like finish and tempering with medium to low frequency heat treating equipment guarantees maximum strength.
7.Each bulldozer track roller is precision machined to house special high impact low wear bimetal bushings.
8.Lubrication oil of our bulldozer bottom rollers 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.
9.Collars of bulldozer lower rollers are made by ductile iron. It shows exceptional resisitance to shock.
Technical requirement of D60A-8 Bulldozer Lower Roller
1. All parts shall be cleaned before assembly without any sundries;
2. Apply a small amount of clean oil to the grinding surface of the floating seal ring; ensure the axial direction after assembly
The displacement is 0.3-0.6 mm
3. Carry out the pressure test before oil injection, and there is no air leakage under the pressure of 0.5-0.6mpa;
4. After installation, inject clean sae80w-90 gear oil (the oil volume accounts for about the cavity
90% ~ 95% of the volume;
5. Run it in for 3-5 minutes after refueling to make it operate smoothly;
6. After the surface is clean, spray two coats of antirust paint.
