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 at each production facility possess specialized knowledge of the components produced, while the headquarters of Italian Engineering 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 specified degree of track tension. Efficient chain tension is a key factor affecting undercarriage durability. Optimal deflection for conventional tracks is about 50mm (+-5mm). For example, a track in an 80-horsepower machine with a deflection of 12mm will have a tension of 2540 kg when measured at the track tensioner. Meanwhile, the same machine, with the suggested deflection of 50mm, will have a tension value of 362 kg. An excessively tight track increases pressure, resulting in greater wear of the track bushings and drive wheel teeth, as well as chain contact with the tensioning wheel and rollers. Appropriate tread hardness, equal to or greater than the chain links and support rollers, ensures resistance to impacts and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication ensures minimal maintenance throughout the service life.
