Spannrad mit Führungen DAEWOO DX60 R
Track tensioning wheel. Inner guide flange width 52mm complete with shaft.
Idler wheels ITR for mini excavators and compact loaders are manufactured using the latest automated design and production processes.
ITR Tensioning Wheel for DAEWOO DX60 R
They are made from selected high-quality steel alloys and appropriately 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, produced in accordance with the most stringent industry specifications. Assembly takes place on assembly lines with an automatic oil filling process. Idler wheels can be chosen in various configurations:
- Tensioning wheel shell
- Tensioning wheel with sleeve and shaft
- Tensioning wheel with brackets
- 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). Engineering and R&D departments are located in Italy, South Korea, and China, working together to combine know-how, technology, and development capabilities. The engineering departments located in each production facility have specific knowledge of locally produced components, while the Italian Engineering headquarters 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 specific degree of track tension. The most important controllable factor in undercarriage wear is 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 12mm sag 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. An excessively tightened track increases pressure, resulting in greater wear on the track bushings when in contact with the sprocket teeth and in the chain-tensioning wheel-roller contact. Tread hardness equal to or greater than chain links, track rollers, and support rollers ensures impact resistance and balanced durability. Material type: SCMn3A, hardening 50-55 HRC. Lifetime lubrication to minimize maintenance.
