ITR Idler Wheel for KOMATSU CD60R
Our Idler wheels are made from selected high-quality steel alloys and are properly heat-treated to ensure exceptional field performance in extreme working conditions. They are assembled using state-of-the-art seals and bearing designs that meet the industry's most stringent specifications. Our Idler wheels are assembled on production lines with an automatic oil filling process to ensure their reliability and durability.
Available in various configurations, which include:
- Idler wheel shell
- Idler wheel with sleeve and shaft
- Idler wheel with brackets
- Idler wheel with fork
- Idler wheel with tensioner
Our Idler wheels are designed to meet all working requirements in tough conditions, ensuring reliability and long life.
Quality of ITR Idler Wheels
Our range includes a wide selection of idler 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 at each production facility have specialized knowledge of the components produced, while the headquarters Italian Engineering coordinates all activities.
Functionality of ITR Idler Wheels
The function of the idler wheel is to properly tension and guide the track chain, ensuring its correct winding. The idler wheel and tensioner work together to maintain a specific degree of track tension. Proper chain tension is a key factor affecting the durability of the undercarriage. Optimal sag for conventional tracks is approximately 50mm (+-5mm). For example, a track on an 80-horsepower machine with 12mm sag will have a tension of 2540 kg when measured at the track tensioner. Meanwhile, the same machine, with the suggested sag of 50 mm, will have a tension of 362 kg. An excessively tight track increases pressure, leading to greater wear of the track bushes and drive wheel teeth, as well as contact of the chain with the idler wheel and rollers. Proper tread hardness, equal to or greater than that of the chain links and support and carrier rollers, provides impact resistance and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication minimizes maintenance throughout the life span.
