Excavator Carrier Roller: Definition, Function, Principle and Maintenance Tips

Function

  • Supporting equipment weight: The carrier rollers are distributed on both sides of the crawler chassis, which can evenly share the weight of the excavator, prevent direct friction between the crawler and the ground, and reduce the workload of the crawler.
  • Guide the crawler track: By cooperating with the crawler track, the carrier roller ensures that the crawler track runs along the predetermined track, avoids the crawler track from deviating or derailing, and ensures the stability of the excavator.
  • Absorb impact force: During the operation of the equipment, uneven ground may cause impact force, and the carrier roller can effectively absorb these impacts and reduce the loss of the chassis system and crawler track.
  • Improve equipment stability: The carrier roller an important role in weight distribution and dynamic balance, especially when operating on steep slopes or complex terrain.
  • High-precision processing ensures that the outer circle of the carrier roller fits perfectly with the track, running smoothly and wearing evenly.
  • Strict error control, such as outer diameter roundness and bearing fit clearance, is directly related to the product life.
  • The quality of the sealing ring is an important criterion for measuring the performance of the carrier roller. Poor sealing performance may cause mud and water to enter the interior, thereby damaging the bearing.
  • High-performance sealing systems can extend the life of the carrier roller and reduce maintenance costs.
  • The surface hardness of the carrier roller is usually controlled between HRC48-58, which can effectively resist wear and maintain strong impact resistance.
  • Choose a manufacturer with a good industry reputation, whose products are usually rigorously tested and can provide stable quality and excellent after-sales service.

  • When used under harsh working conditions, mud and impurities are easy to adhere to the surface of the carrier roller. These foreign objects should be removed regularly to avoid damage to the bearings and seals.
  • Regularly check whether there are obvious grooves, cracks or abnormal wear on the surface of the carrier roller; pay attention to check whether the bearing is loose or stuck.
  • Add an appropriate amount of lubricating oil to the carrier roller bearing system to ensure its flexible rotation and reduce internal wear.
  • Adjust the lubrication cycle according to the frequency of working conditions to avoid excessive or insufficient lubrication.
  • Regularly check the status of the seal ring, and replace it in time if it is found to be aging, cracked or damaged to prevent external foreign objects from invading.
  • If the track is too tight, the carrier roller may be subjected to excessive pressure, and if it is too loose, it may affect the guiding effect. Therefore, it is very important to adjust the track tension regularly.
  • GFM carrier roller adopt internationally leading heat treatment processes to ensure that the products have high strength and high wear resistance.
