Rollers on mini excavator

manus® 2005
Modified roller on mini excavator  
Exploded view of the modified roller  

"The simplicity of the required modifications makes this solution very cost efficient; they promise an enormous increase in service life of the bearing by the low susceptibility to dirt and humidity, which ultimately leads to an increase in machine availability. The otherwise short maintenance rates can also be entirely avoided with this solution. The stability and load capacity of the mini excavator are likewise essentially enhanced by the higher load rating of the bearing. ”
