Idler wheels ITR for mini excavators and compact loaders are manufactured using the latest automated design and production processes.
ITR Tension Wheel for BOBCAT X322
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 constructions, produced according to the most stringent specifications in the industry. Assembly is carried out on assembly lines with an automatic oil filling process. Idler wheels can be selected in various configurations:
- Tension wheel shell
- Tension wheel with bushing and shaft
- Tension wheel with brackets
- Tension wheel with fork
- Tension wheel with tensioner
Quality of ITR Tension Wheels
The range of tension 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 headquarters of Italian Engineering coordinates all activities.
Functionality of ITR Tension Wheels
The function of the tension wheel is to support the track chain and guide it so that it is properly wound. Additionally, the tension 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 approximately 50mm (+-5mm). For example, a track in an 80-horsepower machine with a sag of 12mm 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 tensioned track increases pressure, causing greater wear on the track bushings when in contact with the drive wheel teeth and in the chain-tension wheel-roller contact. The tread hardness equal to or greater than the 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.
