Spannrad CNH E30 SR
Track tensioning wheel. Width of inner guide flange 30mm complete with shaft.
Track tensioning wheels ITR for mini excavators and compact loaders are manufactured using the latest automated design and production processes.
ITR Tensioning Wheel for CNH E30 SR
They are made from selected high-quality steel alloys and properly heat-treated to ensure exceptional field performance in extreme working conditions. ITR tensioning wheels are assembled using state-of-the-art seals and bearing designs, produced according to the most stringent industry specifications. Assembly takes place on assembly lines with an automatic oil filling process. 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 Tensioning Wheels
The range of tensioning wheels covers 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 work together to combine know-how, technology, and development capabilities. Engineering departments located in each production plant have specific knowledge of locally produced components, while the Italian Engineering headquarters coordinates all activities.
Functionality of ITR Tensioning Wheels
The function of the tensioning wheel is to support the track chain and guide it to be 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 sag for all conventional tracks is approximately 50mm (+-5mm). For example, a track on an 80-horsepower machine with a 12mm sag will have a tension value of 2540 kg when measured at the track tensioner. The same machine with a suggested sag of 50 mm will have a tension value of 362 kg. An overly tight track increases pressure, causing greater wear on the track bushings at the point of contact with the drive sprocket teeth and in the track-tensioning wheel-roller contact. Tread hardness equal to or greater than chain links, track rollers, and supporting rollers ensures impact resistance and balanced durability. Material type: SCMn3A, hardening 50-55 HRC. Lifetime lubrication to minimize maintenance.
