OLA Engineering and Construction Machinery Undercarriage Parts Crawler Heavy-Duty Dozer Bulldozer Single/Double Track Roller

Product Description

BULLDOZER TRACK ROLLER

* The bulldozer's track wheel refers to auxiliary equipment installed on the track system of the bulldozer to increase the grip and stability of the bulldozer.

* The rollers are usually located behind the bulldozer track system and bear the main load-bearing role. Their function is to increase the tractor's traction and bulldozing capabilities by increasing its weight, allowing it to exert greater pressure on the ground.

* The rollers typically adjust the dozer's support by adjusting their position and weight distribution, and by adding or removing counterweights. By adjusting the position and counterweight of the rollers, the bulldozer can have better stability and grip under different working conditions to adapt to different soil and operation requirements.

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.

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.

MAIN STRUCTURE

The main components of the track roller include the wheel body, track roller shaft, bushing, sealing ring, end cover, and other related structural parts.

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.
