Track tensioning wheel. Width of the inner guide flange 68mm complete with shaft.
Idler wheels ITR for mini excavators and compact loaders are manufactured using the latest automated design and manufacturing processes.
ITR Tensioning Wheel for ATLAS TEREX 1205
They are made from selected high-quality steel alloys and properly heat-treated to ensure exceptional field performance in extreme working conditions. Idler wheels ITR are assembled using state-of-the-art seals and bearing designs, manufactured to the most stringent industry specifications. Assembly takes place on assembly lines with automatic oil filling processes. Idler wheels can be selected in various configurations:
- Tensioning wheel shell
- Tensioning wheel with bushing and shaft
- Tensioning wheel with supports
- Tensioning wheel with fork
- Tensioning wheel with tensioner
Quality of ITR Tensioning Wheels
The range of tensioning wheels includes equipment from mini excavators to mining machines from KUBOTA® K008 (machine operating weight 0.9 tons) to KOMATSU® D475 A5 (machine operating weight 101 tons). The engineering and R&D departments are located in Italy, South Korea, and China and work together to combine know-how, technology, and development capabilities. The engineering departments located in each production facility have specific knowledge about locally produced components, while the headquarters Italian Engineering coordinates all activities.
Functionality of ITR Tensioning Wheels
The function of the tensioning wheel is to support the track chain and guide it to be properly wound. Additionally, the tensioning wheel and tensioner work together to maintain a certain 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 in an 80-horsepower machine with a sag of 12mm will have a tension value of 2540 kg when measured at the track tensioner. The same machine with a suggested sag of 50mm will have a tension value of 362 kg. Over-tensioned track increases pressure, causing more wear on the track bushings when in contact with the drive sprocket teeth and in the chain-tensioning wheel-roller contact. Tread hardness equal to or greater than chain links, driving and supporting rollers ensures impact resistance and balanced durability. Material type: SCMn3A, hardening 50-55 HRC. Lifetime lubrication to minimize maintenance.
