- Tensioning wheel with tensioner
Our tensioning wheels are designed to meet all work requirements in challenging conditions, ensuring reliability and long life.
ITR Tensioning Wheels Quality
Our range includes a wide selection of tensioning wheels, from mini excavators to mining machines, providing 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 work together to combine know-how, technology, and development capabilities. Local engineering departments in each production facility possess specialized knowledge of the components produced, and the headquarters Italian Engineering coordinates all activities.
Functionality of ITR Tensioning Wheels
The function of the tensioning wheel is to provide proper tension and guiding of 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 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 at the time of measurement in the track tensioner. Meanwhile, the same machine, at the suggested deflection of 50mm, will have a tension value of 362 kg. An excessively tight track increases pressure, which translates to greater wear of the track bushings and drive wheel teeth, as well as contact of the chain with the tensioning wheel and rollers. Appropriate tread hardness, equal to or greater than that of the chain links and carrier and support rollers, ensures impact resistance and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication ensures minimized maintenance throughout the service life.
