Quality of ITR Tension Wheels
Our range includes a wide selection of tension 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 about the components produced, and the Italian Engineering headquarters coordinates all activities.
Functionality of ITR Tension Wheels
The function of the tension wheel is to appropriately tension and guide the track chain, ensuring its proper winding. The tension wheel and tensioner work together to maintain a specific degree of track tension. Efficient chain tension is a key factor influencing 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 moment of measurement in the track tensioner. In contrast, the same machine, with a suggested deflection of 50mm, will have a tension value of 362 kg. Excessively tight tracks increase pressure, leading to higher wear of the track bushings and drive wheel teeth, as well as contact of the chain with the tension wheel and rollers. Appropriate tread hardness, equal to or greater than the chain links and supporting and carrying rollers, ensures impact resistance and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication minimizes maintenance throughout the service life.
