Quality of ITR Idler Wheels
Our range includes a wide selection of idler 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 plant have specialized knowledge about the manufactured components, while the Italian Engineering headquarters coordinates all activities.
Functionality of ITR Idler Wheels
The function of the idler wheel is to provide appropriate tension and guidance of the track chain, ensuring its proper winding. The idler wheel and tensioner work together to maintain a specific track tension degree. Efficient chain tension is a key factor affecting the undercarriage's durability. The optimal sag for conventional tracks is about 50mm (+-5mm). For example, a track in an 80-horsepower machine with a sag of 12mm will have a tension of 2540 kg at the track tensioner measurement. On the other hand, the same machine, with the suggested sag of 50 mm, will have a tension value of 362 kg. An overly tense track increases pressure, leading to greater wear on the track bushings and drive wheel teeth, as well as contact between the chain and the idler wheel and rollers. Appropriate tread hardness, equal to or greater than the chain links and running and support rollers, ensures impact resistance and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication ensures minimized maintenance throughout the entire operational period.
