Tension wheels for the track. Width of the internal guiding flange 53mm complete with shaft.
Tension wheels ITR for mini excavators and compact loaders ensure optimal track tension through the use of the latest design and manufacturing technologies.
ITR Tension Wheel for HITACHI ZX60 USB
Our tension wheels are made from selected high-quality steel alloys and appropriately heat-treated to ensure exceptional field performance in extreme working conditions. We assemble them using state-of-the-art seals and bearing constructions, meeting the industry's strictest specifications. Our tension wheels are assembled on production lines with an automated 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 work requirements in harsh conditions, ensuring 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 work together to combine know-how, technology, and development capabilities. Local engineering departments at each production facility have specialized knowledge about the components produced, and the headquarters of 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 proper winding. The tension wheel and tensioner work together to maintain a specified degree of track tension. Proper chain tension is a key factor affecting the durability of the undercarriage. Optimal deflection for conventional tracks is about 50mm (+-5mm). For example, a track on an 80-horsepower machine with a 12mm deflection will have a tension of 2540 kg at the time of measurement in the track tensioner. Meanwhile, the same machine, with the suggested deflection of 50mm, will have a tension value of 362 kg. An overly tense track increases pressure, leading to greater wear of the track bushing and drive wheel teeth, as well as contact of the chain with the tension wheel and rollers. Proper tread hardness, equal to or greater than the chain links and support and carrier rollers, ensures impact resistance and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication minimizes maintenance throughout the service life.
