Spannrad YANMAR B08
Track tensioning wheel. Width of the inner guiding flange 23mm 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 YANMAR B08
They are made from selected high-quality steel alloys and are 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 according to the most stringent specifications in the industry. 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 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. 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 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. The correct deflection for all conventional tracks is approximately 50mm (+-5mm). For example, a track on an 80-horsepower machine with a 12mm deflection will have a tension value of 2540 kg when measured at the track tensioner. The same machine with the suggested 50 mm deflection will have a tension value of 362 kg. An excessively tensioned track increases pressure, causing greater wear on the track bushings when contacting the drive wheel teeth and in the chain-tensioning wheel-roller contact. Tread hardness equal to or greater than that of the chain links, drive and support rollers ensures impact resistance and balanced durability. Type of material: SCMn3A, hardening 50-55 HRC. Lifetime lubrication to minimize maintenance.
