Quality of ITR Tensioning Wheels
Our range includes a wide selection of tensioning wheels, from mini-excavators to mining machines, ensuring high quality and performance. Starting from KUBOTA® K008 (with an operating weight of 0.9 tons) up to KOMATSU® D475 A5 (with an operating weight of 101 tons), we offer comprehensive solutions. Our engineering and R&D departments in Italy, South Korea, and China collaborate to combine know-how, technology, and development capabilities. Local engineering departments in each production facility have specialized knowledge of the manufactured components, and the Italian Engineering headquarters coordinates all activities.
Functionality of ITR Tensioning Wheels
The function of the tensioning wheel is to properly tension and guide the track chain, ensuring its correct winding. The tensioning wheel and tensioner work together to maintain a specific degree of track tension. Efficient chain tension is a key factor affecting the durability of the undercarriage. The optimal sag for conventional tracks is about 50mm (+-5mm). For example, a track on an 80-horsepower machine with a sag of 12mm will have a tension of 2540 kg when measured at the track tensioner. Meanwhile, the same machine, at the suggested sag of 50 mm, will have a tension of 362 kg. An overly tight track increases pressure, leading to greater wear on track bushings and sprocket teeth, as well as contact between the chain and the tensioning wheel and rollers. Proper tread hardness, equal to or greater than the chain links and running and supporting rollers, ensures impact resistance and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication minimizes maintenance throughout the service life.
