The range of tensioner wheels includes equipment from mini excavators to mining machines from KUBOTA® K008 (machine working weight 0.9 tons) to KOMATSU® D475 A5 (machine working 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. Engineering departments located in each production facility have specific knowledge of locally produced components, while the headquarters Italian Engineering coordinates all activities.

Functionality of ITR Tensioner Wheels

The function of the tensioner wheel is to support the track chain and guide it to be properly wound. Additionally, the tensioner wheel and adjuster work together to maintain a specific degree of track tension. The most important controllable factor in undercarriage wear is the correct chain 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 adjuster. The same machine with a suggested sag of 50mm will have a tension value of 362 kg. An excessively tight track increases pressure, causing greater wear on the track bushings when in contact with the drive wheel teeth and in the chain-tensioner wheel-roller contact. Tread hardness equal to or greater than 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.

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.

Functionality of ITR Tensioning Wheels

Tensioning wheels are a key element in maintaining the proper tension and guidance of the track chain, which translates into its proper winding. They work together with the adjuster to maintain optimal tension, which is crucial for the durability of the undercarriage. Correct tension setting, for example, 50 mm (+-5mm) for conventional tracks, has a significant impact on machine wear and performance. For instance, an excessively tight chain can lead to greater wear of the track bushings and sprocket teeth. The appropriate hardness of the tread, equal to or greater than the chain links and running and supporting rollers, provides resistance to damage and increases durability. Material: SCMn3A, hardening 50-55 HRC. Continuous lubrication helps minimize maintenance during operation.
