SH75 SH120 SH200 SH350 Excavator roller assembly for mini excavator parts

Traditional Excavator Track Rollers are one of the key components in the track system of an excavator, primarily used to support and guide the movement of the track. The design and manufacturing quality of these rollers directly impact the operational efficiency and service life of the excavator. Traditional track rollers are typically made of high-strength alloy steel, offering excellent wear resistance and impact resistance, ensuring stable performance even in harsh working conditions.

Structure and Function

The structure of traditional track rollers is relatively simple, consisting mainly of the wheel body, bearings, seals, and a lubrication system. The wheel body, which is the main part of the roller, is usually manufactured using forging processes to ensure its strength and durability. Bearings are used to support the wheel body, allowing it to rotate smoothly. Seals and the lubrication system prevent dust, mud, and other debris from entering the bearings, thereby extending the service life of the roller.

The primary function of the track roller is to support the track, reduce friction between the track and the ground, and guide the track along a predetermined path. During the operation of the excavator, the track roller must withstand significant loads and impact forces, necessitating designs and manufacturing processes that meet high strength and wear resistance requirements.

Materials and Manufacturing Processes

Traditional track rollers are typically made from high-strength alloy steel, a material known for its excellent mechanical properties and wear resistance. In terms of manufacturing processes, the wheel body is usually forged to ensure the density and uniformity of its internal structure. After forging, the wheel body undergoes heat treatment to further enhance its hardness and wear resistance.

Bearings are another critical component of the track roller, typically using high-precision rolling bearings or sliding bearings. Rolling bearings have a low friction coefficient and high load capacity, making them suitable for high-speed rotation applications. Sliding bearings, on the other hand, offer better impact resistance and are suitable for heavy-load and low-speed rotation applications.

Seals and the lubrication system are essential components of the track roller, designed to prevent dust, mud, and other debris from entering the bearings, thereby extending the roller's service life. Seals are usually made of rubber or polyurethane, materials known for their elasticity and wear resistance. The lubrication system uses grease or oil to ensure smooth bearing operation.

Applications and Maintenance

Traditional track rollers are widely used in various types of excavators, including small, medium, and large excavators. In practical applications, these rollers require regular inspection and maintenance to ensure their proper functioning. Maintenance tasks primarily include lubrication, cleaning, and replacing worn parts.

Lubrication is a crucial aspect of track roller maintenance; regularly applying lubricating oil or grease can significantly reduce bearing wear and extend the roller's service life. Cleaning involves removing mud and debris from the roller's surface to prevent them from entering the bearings. For severely worn rollers, timely replacement is necessary to avoid affecting the excavator's normal operation.

• Excavators are heavy machinery widely used in various fields such as construction, engineering, and mining. The main application areas include:
•  
• Construction engineering: Excavators are used for excavating foundation pits, cleaning sites, excavating underground facilities, foundation construction, etc.
•  
• Mining: In mines, excavators are used for mining ores, transporting materials, stripping topsoil, and crushing operations.
•  
• Water conservancy engineering: In water conservancy construction, excavators are used to excavate rivers, clear lakes, build dams and canals, etc.
•  
• In the field of agriculture, excavators are sometimes used to cultivate land, dig water channels, and construct irrigation systems in large-scale agricultural production.
•  
• Forestry: used for logging, clearing forest paths, clearing trees, and transporting timber.
•  
• Railway construction and maintenance: It is also applied in the excavation of railway lines, filling of ballast beds, construction of bridges and tunnels, and other aspects.
