Umlenkrad mit Führungen MOROOKA MST800
Track tensioning wheel. Inner guide flange width 60mm complete with shaft.
Idler wheels ITR for mini excavators and compact loaders are manufactured using the latest automated design and production processes.
ITR Idler Wheel for MOROOKA MST800
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, manufactured according to the industry's most stringent specifications. Assembly takes place on assembly lines with an automatic oil filling process. Idler wheels can be chosen in various configurations:
- Idler wheel shell
- Idler wheel with bushing and shaft
- Idler wheel with brackets
- Idler wheel with fork
- Idler wheel with tensioner
Quality of ITR Idler Wheels
The range of idler 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 and collaborate to combine know-how, technology, and development capabilities. Engineering departments located at each production facility have specific knowledge about locally manufactured components, while the Italian Engineering headquarters coordinates all activities.
Functionality of ITR Idler Wheels
The function of the idler wheel is to support the track chain and guide it so that it is appropriately wound. Additionally, the idler wheel and tensioner work together to maintain a specified degree of track tension. The most important controllable factor in undercarriage wear is correct chain tension. The correct sag for all conventional tracks is approximately 50mm (+-5mm). For example, a track on an 80-horsepower machine with a sag of 12mm will have a tension of 2540 kg when measured at the track tensioner. The same machine with a suggested sag of 50mm will have a tension of 362 kg. An excessively tensioned track increases pressure, leading to greater wear on track bushings when in contact with the drive wheel teeth and at the chain-idler wheel-roller contact. Tread hardness equal to or greater than that of 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.
