The SK60 Top Roller for Kobelco Undercarriage Parts is an excavator undercarriage component developed by Kobelco for small‑scale working conditions.
Compact in size and versatile in application scenarios, it serves as a critical part of the excavator undercarriage system. It ensures smooth operation and stable structure of the whole undercarriage.
Kobelco‑spec undercarriage parts require raw materials with high hardness and superior wear‑resistance.
How FAJX Parts Casts the SK60 Top Roller From Raw Materials
To extend the service life of SK60 top rollers, FAJX Parts has co‑developed new molecular‑reinforced material for Kobelco mini‑excavator undercarriage parts together with Chinese universities.
Added during the casting process, this material delivers a 19% longer service life compared with conventional products.
It performs reliably under harsh working conditions including muddy ground, freezing cold, high temperature and rough uneven terrain.
It greatly improves the top roller’s surface hardness, impact resistance and continuous load‑bearing capacity.

FAJX Parts Manufacturing Process and Quality Control
FAJX Parts exercises strict quality control starting from the cast‑steel raw material for every SK60 top roller.
Premium 50Mn alloy steel is selected and tested for chemical composition via spectrometer in our in‑house laboratory, to guarantee consistent quality for each Kobelco undercarriage part.
After high‑temperature melting and pouring for casting forming, workpieces go through shot blasting to remove oxide scale. Casting defects such as porosity, sand holes and cracks are carefully inspected and eliminated.
Every top roller is built to high‑quality standards right from the source, delivering more reliable performance for our wholesale orders.
Manufacturing Process
How to Select a Quality SK60 Track Carrier Roller
The SK60 top roller is an undercarriage component for Kobelco SK60‑series excavators.
Raw material must be 50Mn or 40Mn2 alloy steel. If suppliers adopt other materials, insufficient steel hardness will easily cause cracking during operation.
Surface hardness shall reach HRC 48‑58. Improper heat‑treatment will lead to rapid wear‑out of the top roller.
Double‑lip floating oil seal is mandatory. It can effectively retain internal lubricating oil for sufficient roller lubrication, and withstand high temperatures generated during machine operation.
FAQ
Q：Are the carrier rollers for SK60-3, SK60-6, and SK60-8 interchangeable?
They are NOT interchangeable. SK60‑3 / SK60‑6 uses OEM No.24100N6510F1, while SK60‑8 uses YT64D01001F1 with different dimensions. Please confirm your machine version before ordering. You may send us photos or original part number for double‑check.
Q:What material is the SK60 carrier roller made of?
Roller body is made of 50Mn alloy steel; 40Mn2 material is also optional. Shaft adopts quenched & tempered 45# steel. Reinforced material is added during casting process, surface hardness reaches HRC52‑58 for better crack‑resistance and wear performance.
Q:What is the seal structure of the FAJX Parts SK60 carrier roller? Will it leak oil?
Equipped with double‑lip floating oil seal and pre‑filled gear oil from factory. Every unit passes air‑tightness pressure test. Under correct installation, it blocks dirt and withstand high‑temperature working conditions to minimize oil‑leak risk. Improper installation will damage seals and cause leakage.
Q:Are SK60 carrier rollers in stock? What is the MOQ?
SK60 top rollers are in stock. Our annual output reaches 200,000 pcs. No MOQ requirement, sample, small‑batch and wholesale bulk orders are all acceptable.
