Mini Excavator Bottom Track Roller Part NO.169-3388
MUYE 169-3388 track roller is a load-bearing undercarriage component designed exclusively for Kubota E303 mini excavator. It supports machine weight and guides track links during traveling, digging and landscaping operations on narrow construction sites.
The roller body is manufactured from high-strength forged alloy steel with surface quenching treatment to enhance surface hardness and wear resistance. Adopting advanced multi-layer floating oil seal structure, it effectively blocks mud, water and fine dust from invading internal bearing assembly, preventing oil leakage and premature failure under muddy working conditions. Precision machined shaft and bearing guarantee flexible rotation under continuous load.
Each track roller undergoes load pressure testing, tightness inspection and anti-corrosion coating before delivery. Compared with ordinary cast rollers, this forged track roller delivers stronger impact resistance and longer service life during frequent travel.
MUYE Machinery supplies full range Kubota mini excavator undercarriage spare parts including track rollers, carrier rollers, idlers, sprockets and track chains, and supports customized undercarriage component solutions according to customer requirements. 169-3388 track roller is available in stock with fast global shipping service.
