Spannrad mit Führungen KOBELCO SK45 SR
Track tensioning wheel. Width of the inner guiding flange 40mm complete with a shaft.
Idler wheels ITR for mini excavators and compact loaders are manufactured using the latest automated design and production processes.
ITR Tensioning Wheel for KOBELCO SK45 SR
They are made from selected high-quality steel alloys and appropriately heat-treated to provide exceptional field performance in extreme working conditions. Idler wheels ITR are assembled using state-of-the-art seals and bearing designs, manufactured to the industry's most stringent specifications. Assembly takes place on assembly lines with an automatic oil filling process. Idler wheels can be selected in various configurations:
- Tensioning wheel shell
- Tensioning wheel with bushing 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 machinery 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 and collaborate to combine know-how, technology, and development capabilities. Engineering departments 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 so that it is 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. 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 tension of 2540 kg when measured at the track tensioner. The same machine with the suggested sag of 50mm will have tension of 362 kg. An excessively tense track increases pressure, which causes more wear on the track bushings at the moment of contact with the sprocket teeth and in the chain-tensioning wheel-roll contact. Tread hardness equal to or greater than the track links, drive, and support rollers ensures impact resistance and balanced durability. Material type: SCMn3A, hardening 50-55 HRC. Lifetime lubrication to minimize maintenance.
