Tension wheels for the track. Width of the inner guiding flange 44mm complete with a shaft.
Tension wheels ITR for mini-excavators and compact loaders ensure optimal track tension by employing the latest design and manufacturing technologies.
ITR Tension Wheel for BOBCAT T590
Our Tension wheels are made from selected high-quality steel alloys and are properly heat-treated to provide exceptional field performance in extreme working conditions. We assemble them using state-of-the-art seals and bearing designs, meeting the industry's most stringent specifications. Our Tension wheels are assembled on production lines with an automatic oil filling process, ensuring their reliability and durability.
They are available in various configurations, including:
- Tension wheel shell
- Tension wheel with bushing and shaft
- Tension wheel with brackets
- Tension wheel with fork
- Tension wheel with tensioner
Our Tension wheels are designed to meet all requirements for working in tough conditions, providing reliability and long life.
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 of the components produced, and the headquarters Italian Engineering coordinates all activities.
Functionality of ITR Tension Wheels
The function of the tension wheel is to properly tension and guide the track chain, ensuring its correct winding. The tension wheel and tensioner work together to maintain the specified degree of track tension. Proper chain tension is a key factor affecting the durability of the undercarriage. Optimal sag for conventional tracks is about 50mm (+-5mm). For example, a track in a machine with 80 horsepower with a sag of 12mm will have a tension of 2540 kg when measured at the track tensioner. The same machine, at the suggested sag of 50mm, will have a tension of 362 kg. An excessively tight track increases pressure, which translates to greater wear of the track bushing 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 that of the chain links and track rollers and supports, ensures impact resistance and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication ensures minimized maintenance throughout the entire life cycle.
