Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The track adjuster on a mini excavator like the SK35 is responsible for keeping the rubber or steel track properly tensioned at all times. This prevents slack, reduces track derailment, and minimizes stress on the sprockets, idlers, and rollers.
For compact machines, where agility and reliability are critical, a responsive and sealed tensioning system helps improve traction, protect the undercarriage, and ensure consistent performance on various jobsite terrains—from soft mud to concrete demolition.
Design Features with Structural Reference
Our SK35 tensioner is engineered with a space-efficient but heavy-duty design. Here’s a breakdown based on the internal and external structure (we can reference exploded or section diagrams if available):
- High-Tension Recoil Spring – Made from heat-treated spring steel for long fatigue life and smooth recoil force
- Precision Forged Cylinder – CNC-machined to exact tolerances; treated for wear and impact resistance
- Grease Chamber System – Enables manual adjustment of track length via grease pressure
- Sealed Interface – High-quality O-rings and dust seals protect internal components from mud, sand, and water intrusion
This setup allows for precise, tool-free field adjustment using only a grease gun, and maintains tension even after long periods of continuous travel.
Materials & Surface Treatment
- Spring Material: 60Si2Mn or equivalent for resilience under repeated compression
- Cylinder & Piston: 40Cr or 45# forged steel, surface hardened to HRC 48–55
- Seal Group: Durable oil-resistant and wear-resistant rubber compounds (NBR/Viton)
- Surface Finish: Anti-rust paint or black oxide coating for long-lasting protection in humid or corrosive environments
