Product Description

EXCAVATOR TRACK WHEELSv

* Excavator track wheels refer to an important part of the excavator, located on both sides of the excavator chassis, used to provide additional support and stability to increase the excavator's anti-overturning ability. Track wheels are usually made of die-cast iron, cast steel, or welded steel plates and have a certain weight.

* The main function of the excavator track wheels is to share the weight of the excavator, increase the support area and stability of the excavator chassis, and enable the excavator to have better anti-overturning ability when working.

* When the excavator is performing high-intensity work, the track wheels can share part of the weight by increasing the support area, thereby reducing the pressure and load of the track on the ground, reducing damage to the ground, and increasing the stability of the excavator.

Spokes:
The spokes are the components that connect the rim and the axle. They are usually made of steel and are welded or bolted to the rim to support and transmit force to the axle.

Bearings:
The bearing is a key component of the roller, responsible for supporting and keeping the shaft rotating smoothly. Rolling bearings or sliding bearings are usually used, which have high load capacity and durability.

Axle:
The axle is the core structure of the roller, usually made of steel, which bears the weight of the fuselage and transmits force connected to the support frame of the excavator chassis.

EXCAVATOR TRACK ROLLERS

Excavator track rollers refer to auxiliary equipment installed on the excavator track system to increase the excavator's grip and stability.

Track rollers are usually located behind the excavator track system and bear the main load-bearing role. Their function is to increase the excavator's traction capacity by increasing the weight of the excavator and exerting greater pressure on the ground.

Track rollers are usually used to adjust the support of the bulldozer by adjusting their position and weight distribution, as well as adding or reducing counterweights. By adjusting the position and counterweight of the track rollers, the excavator can have better stability and grip under different working conditions to adapt to different soil and operating requirements.

FIXED POSITION AND FUNCTION

The track roller is fixed under the track roller frame with screws to support the weight of the locomotive and distribute it to the track plate, transfer the weight of the locomotive to the ground and roll on the track, prevent derailment, and prevent the track from moving laterally relative to each other.

The track roller often works in mud, water, ash, and sand, is subjected to strong impact, and the working conditions are extremely harsh, and the rim is easy to wear. Therefore, the requirements for the track roller include wear resistance and reliable bearing sealing.

ADVANCED BEARING SYSTEM

High-safety floating oil seals and sealing rings to improve the service life, the new bearing system has a good rolling coefficient and low heat generation.

Equipped with high-security floating oil seals and sealing rings to prevent leakage. No matter how heavy your heavy machine is, our track rollers are designed to serve you for a long time.

MANUFACTURING PROCESS

Double cone seal and lifetime lubrication design make the roller have a super long service life and perfect performance under any working conditions.

The roller shell treated by warm forging has a unique internal material fiber flow distribution structure.

Differential quenching or through quenching heat treatment can ensure a certain heat treatment hardness depth, thus having a good anti-cracking effect.

PROTECTIVE FUNCTION

Rollers also protect the chassis and other components. they disperse the load transmitted by the tracks, reduce the impact on the excavator chassis structure, and reduce the risk of damage to other parts of the chassis (such as chain rails, spindles, etc.).

High-performance rollers can effectively extend the service life of the entire excavator.
