Deep Hardened Roller Surface
The roller body undergoes carburizing quenching treatment to achieve high surface hardness, extending service life significantly on muddy and rocky construction sites.
Double Layer Anti-Leak Oil Seal
High-temperature resistant rubber seals block mud and sediment ingress, effectively prevent grease leakage and prolong lubrication maintenance intervals.
Heavy-Duty Internal Bearing
