Spannrad mit Führungen BOBCAT T190
Track tensioning wheel. Width of the inner guiding flange 44mm complete with shaft.
Track tensioning wheels ITR for mini excavators and compact loaders are manufactured using the latest automated design and production processes.
ITR Track Tensioning Wheel for BOBCAT T190
They are made from selected high-quality steel alloys and are properly heat-treated to ensure exceptional field performance in extreme working conditions. Track tensioning wheels ITR are assembled using state-of-the-art seals and bearing designs, manufactured to the industry's most stringent specifications. Assembly is done on production lines with an automated oil-filling process. Track tensioning 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 Track 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 and collaborate to combine know-how, technology, and development capabilities. Engineering departments located in each production facility have specific knowledge about locally produced components, while the Italian Engineering headquarters coordinates all activities.
Functionality of ITR Track Tensioning Wheels
The function of the track 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 deflection for all conventional tracks is about 50mm (+-5mm). For example, a track on an 80-horsepower machine with a deflection of 12mm will have a tension of 2540 kg when measured at the track tensioner. The same machine with the suggested deflection of 50mm will have a tension of 362 kg. An excessively tensioned track increases pressure, which causes more wear on the track bushings when in contact with the drive sprocket teeth and in the chain-tensioning wheel-roller contact. A tread hardness equal to or greater than the chain links, drive and carrier rollers ensures impact resistance and balanced durability. Material type: SCMn3A, hardening 50-55 HRC. Lifetime lubrication to minimize maintenance.
