Description

The track adjuster (tensioner) is an essential part of the DH55 undercarriage system, helping keep the track properly tensioned during operation. It fulfills two main purposes:

  • Maintains Tension – Prevents track slack or derailment, reducing excessive wear on the sprocket, idler, and track links.
  • Absorbs Shock – The internal recoil spring reduces vibration and mechanical stress, improving the excavator’s handling on uneven ground.

Without a reliable tensioner, the machine becomes less stable and the entire undercarriage system can wear prematurely.

Structural Overview

From our structural diagram and cross-sectional diagram, we can see that our products have the following advantages:

  • Recoil Spring Compartment: Optimized for compact stroke and return action
  • Cylinder Barrel: Machined precisely to house piston and seal set
  • Grease Valve Location: Front-facing for easy maintenance access
  • Mounting Ends: Standard bracket sizing compatible with DH55 idler and frame layout

This layout ensures consistent tension in tight conditions like trenching, foundation prep, or roadside maintenance.

Manufacturing & Material Advantages

Our DH55 track adjuster assembly is manufactured with a focus on precision, strength, and long-term durability:

  • Cylinder Body: Made from 45# or 40Mn alloy steel, CNC-machined for sealing surface and structural strength.
  • Recoil Spring: Built from 60Si2Mn spring steel for high rebound strength and fatigue resistance.
  • Grease Chamber: Built-in chamber with easily accessible grease valve for quick track adjustments on site.
  • Seal System: Water- and dust-proof seals protect against mud, sand, and wet terrain.
  • Surface Coating: Black oxide or paint-treated to prevent rust during storage and use.

Each tensioner is tested for smooth stroke performance, leak resistance, and mounting tolerance.
