Excavator Carrier Roller
The excavator carrier roller refers to a key component located on the excavator's Track System. Its Function Is To Support The Track Links To Maintain The Correct Track And Transfer The Weight Of The Vehicle.The Excavator Carrier Roller Bears Heavy Loads And Pressures When Working. Due To Its Special Design And Material Selection, The Carrier Wheel Can Withstand And Disperse These Forces, Ensuring That The Excavator Works Smoothly.
At The Same Time, The Design Of The Excavator Carrier Roller Also Takes Into Account Factors Such As Improving Operating Comfort, Reducing Noise, And Reducing Wear, To Improve The Performance And Life Of The Excavator.
Rim:
The Outer Circular Part Of The Excavator Carrier Roller is usually Made Of Wear-Resistant Metal Materials, Such As High-Strength Steel Or Alloy Steel. There Are Densely Arranged Tooth Grooves Or Protrusions On The Rim For Contact With The Track Links.
Center Bearing:
Located At The Center Of The Excavator Carrier Roller, It Is Used To Support The Rotation Between The Carrier Wheel And The Track Link. Center Bearings Usually Consist Of Special Needle Bearings Or Rolling Bearings To Withstand The Weight And Impact From The Track Links And The Ground.
