MUYE 21S-3000110 track roller is a load-bearing undercarriage component matched for Komatsu PC30 mini excavator. It supports machine weight and guides track links during travelling, digging and landscaping work on narrow construction sites.
The roller body is produced with high-strength forged alloy steel and surface quenching treatment for outstanding wear resistance. Equipped with advanced multi-layer floating oil seal structure, it effectively blocks mud, water and fine dust from entering the internal bearing chamber, preventing oil leakage and premature bearing damage under muddy and severe working environments. Precisely machined shaft and bearing assembly guarantee stable rotation under continuous load.
Each track roller undergoes static load testing, oil tightness inspection and anti-rust surface coating before shipment. Compared with ordinary cast track rollers, our forged roller provides stronger impact resistance and longer service life under frequent traveling operations.
MUYE Machinery supplies full series Komatsu mini excavator undercarriage spare parts including track rollers, carrier rollers, idlers, sprockets and track chains, and supports customized undercarriage component solutions according to customer demands. 21S-3000110 track roller is available in stock with fast global shipping service.
