275400248 XCMG GR2605 motor grader chain

275400248 XCMG GR2605 motor grader chain

The 275400248 chain is a high-strength transmission and traction component specifically designed for construction machinery. Primarily used for power transmission, driving, or lifting heavy objects, it features high load capacity, wear resistance, and impact resistance, making it a core transmission component ensuring reliable equipment operation and high efficiency.

Core Technical Parameters

Model: 275400248, a chain specifically designed for construction machinery. Specifications and pitch are designed for the power and transmission systems of specific equipment models, and there are usually no universal alternatives.

Suitable Media: Its core function is mechanical transmission and traction; there is no specific transmission medium.

Material: Made of high-quality alloy steel, precision machined and heat-treated (e.g., quenching and tempering), possessing high strength, high hardness, and excellent wear resistance.

Operating Temperature: -30℃ ~ 150℃, adaptable to the normal operating temperature range of construction machinery. The heat treatment process ensures stable chain performance under temperature variations.

Surface Treatment: Performs blackening, galvanizing, or oil spraying for rust prevention, enhancing corrosion resistance and extending service life in humid and dusty outdoor environments.

Specifications and Dimensions: Key dimensions such as chain link pitch, roller diameter, and inner link width strictly match the original equipment design to ensure precise meshing with the sprocket and stable transmission.

Lubrication Requirements: Regular application of dedicated chain lubricant or grease is required to reduce wear between chain links, lower operating noise, and prevent rust.

Core Functions and Roles

As a crucial transmission component in construction machinery, its core function is to efficiently and reliably transmit power from the drive unit (such as a motor or engine) to the actuators (such as the traveling mechanism and lifting mechanism). It is commonly used in excavators, cranes, drilling rigs, and other equipment for tracked drive, lifting, and material conveying. Its high load capacity ensures the equipment can handle heavy-duty operations; excellent wear resistance and fatigue strength ensure long-term stable operation under harsh conditions of high speed and high impact, reducing downtime; precise dimensional fit ensures smooth transmission and reduces power loss. It is a core component directly affecting the equipment’s operating efficiency, safety, and service life.

Suitable Applications

Widely used in excavator track drive systems, crane lifting mechanisms, horizontal directional drilling rig pullback and drilling systems, and conveyor transmission systems. Particularly suitable for harsh working conditions involving heavy loads, impacts, dust, and humidity, such as mining, earthmoving, material handling, and infrastructure construction.
