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 site possess specialized knowledge about 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 specified degree of track tension. Efficient chain tensioning is a critical factor affecting the durability of the undercarriage. 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 time of measurement in the track tensioner. On the other hand, the same machine, with the suggested sag of 50 mm, will have a tension of 362 kg. An overly tensioned track increases pressure, leading to greater wear of the track bushing and sprocket teeth, as well as contact of the chain with the tensioning wheel and rollers. Appropriate tread hardness, equal to or greater than the chain links and supporting rollers, ensures impact resistance and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication ensures minimized maintenance throughout its operational life.

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.

The range of tensioning wheels covers equipment from mini excavators to mining machines from KUBOTA® K008 (machine operating weight 0.9 tons) to KOMATSU® D475 A5 (machine operating weight 101 tons) Engineering and R&D departments are located in Italy, South Korea, and China and collaborate to combine know-how, technology, and development capabilities. The engineering departments located in each production plant have specific knowledge about locally produced components, while the headquarters of Italian Engineering coordinates all activities.

Functionality of ITR Tensioning Wheels

The function of the tensioning wheel is to support the track chain and guide it so it is properly wound. Additionally, the tensioning wheel and tensioner work together to maintain a specific degree of track tension. The most important controllable factor in undercarriage wear is the correct track tension. The correct sag for all conventional tracks is about 50mm (+-5mm). For example, a track on an 80-horsepower machine with a sag of 12mm will have a tension value of 2540 kg when measured at the track tensioner. The same machine with the suggested sag of 50 mm will have a tension value of 362 kg. An overly tightened track increases pressure, which causes more wear on the track bushings when in contact with the sprocket teeth and in the chain-tensioning wheel-roller contact. Tread hardness equal to or greater than that of the chain links, drive and support rollers ensures impact resistance and balanced durability. Material type: SCMn3A, hardening 50-55 HRC. Lifetime lubrication to minimize maintenance.
