D8K Double Flange Bottom Roller 7S9042 Undercarriage Track Rollers DF Top Roller

1. What is a roller?

Guidance rollers ensure smooth and precise mechanical movement along operational tracks through the implementation of dual welding methodologies: conventional fusion welding complemented by advanced friction-stir welding technology. Following specialized hardening and tempering treatments, these components demonstrate exceptional mechanical properties characterized by superior durability, along with significantly improved resistance to plastic deformation and structural failure under load conditions.

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.

* TEngineered 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.
