Product Features
Superior Wear‑Resistant Hardened Tread Surface: This single‑flange track roller is made of high‑strength alloy steel, with deep induction hardening on tread and flange surfaces reaching HRC 52‑58 hardness. Deep hardened wear‑resistant layer absorbs continuous ground impact, delaying surface abrasion and avoiding early failure under harsh construction‑site conditions.
Reliable Duo‑Cone Floating Seal Assembly: Equipped with high‑precision duo‑cone floating metal seals and resilient NBR O‑rings, pre‑filled with long‑life extreme‑pressure lubricant. It effectively blocks mud, sand and debris intrusion, keeps internal lubricant sealed, and reduces frequent maintenance workload.
Precise Single‑Flange Structural Fitment: Heavy‑duty single‑flange design ensures stable machine‑weight support and correct track guiding for matched excavator undercarriage system. Good dimensional accuracy guarantees seamless installation, reduces track offset risk and delivers steady rolling performance.
Friendly Reminder: Please ensure this part number matches your machine model and serial number. We strongly recommend checking with the official parts catalog or providing your machine serial number before purchase to avoid ordering the wrong part.
