Tensioning wheels ITR for mini excavators and compact loaders provide optimal track tension by using the latest design and manufacturing technologies.
ITR tensioning wheel for KOMATSU CD60R
Our Tensioning wheels are made from selected high-quality steel alloys and properly heat-treated to ensure exceptional field performance in extreme working conditions. We assemble them using state-of-the-art seals and bearing structures, meeting the most stringent industry specifications. Our Tensioning wheels are assembled on production lines with an automatic oil filling process, ensuring their reliability and durability.
Available in various configurations, including:
- Tensioning wheel shell
- Tensioning wheel with bushing and shaft
- Tensioning wheel with brackets
- Tensioning wheel with fork
- Tensioning wheel with tensioner
Our Tensioning wheels are designed to meet all work demands in harsh conditions, ensuring reliability and long life.
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) 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 site have specialized knowledge of the components produced, 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 the tensioner work together to maintain a specified degree of track tension. Proper chain tension is a key factor affecting undercarriage durability. The optimal deflection for conventional tracks is about 50mm (+-5mm). For example, a track on an 80-horsepower machine with a deflection of 12mm will have a tension of 2540 kg when measured at the track tensioner. However, the same machine, with a suggested deflection of 50mm, will have a tension of 362 kg. An overly tight track increases pressure, leading to greater wear of the track bushings and sprocket teeth, as well as contact of the chain with the tensioning wheel and rollers. Proper tread hardness, equal to or greater than that of the chain links and track rollers, ensures impact resistance and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication minimizes maintenance throughout the service life.
