Product Description

 PC30-7 Mini Excavator Undercarriage Replacement Parts - Factory Direct Track Rollers & Engine Bottom Components

1. What is a roller?

The roller, a pivotal element in the belt conveyor system, plays a vital role in supporting both the conveyor belt itself and the weight of the materials being transported. Accounting for 35% of the total cost of the belt conveyor, the roller is responsible for generating over 70% of the operational resistance, thereby emphasizing the paramount importance of roller quality. In terms of manufacturing techniques, there are two prevalent methods: the conventional welding process and friction welding. The latter technique results in the production of exceptionally robust friction-welded track rollers.

2. Track Rollers Excavator Advantages / Features

* All rollers are through the casing leakage test under 0.6Mpa gas pressure to ensure the longer working life.

* Through quench-tempering processes to ensure excellent mechanical properties, high strength and superior wear resistance to bending and breakage.

* Our track roller systems exemplify engineered excellence through precision-controlled thermal cycling protocols and field-proven mining application data integration. 

* Our heavy-duty track rollers are built to handle tough conditions. Using specially treated steel and reliable sealing technology, they carry heavier loads and last longer, even in mining operations. Backed by a quality guarantee. 

* Engineered for maximum operational longevity, these track rollers integrate precision-machined components with optimized thermal processing protocols and hermetic sealing architectures. The forged shells utilize deep-case hardening alloy steel specifically formulated to maintain dimensional integrity under cyclical loading conditions. Full product lifecycle protection is provided through original equipment manufacturer certification.
