Product Description

Mini Excavator High Quality Bottom Track Roller for Komatsu PC20-3 

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

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

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

* We take pride in the quality of our track rollers. The excellent heat treatment processes and our experimental basis of mining, the high quality floating seals and bearing lead our company to produce heavy-duty type and much more durable products.

* 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.
