Idler wheels ITR for mini excavators and compact loaders are manufactured using the latest automated design and production processes.

ITR Tensioning Wheel for PEL JOB SIRIUS PLUS

They are made from selected high-quality steel alloys and are properly 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 industry's most stringent specifications. 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 sleeve 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 working weight 0.9 tons) to KOMATSU® D475 A5 (machine working weight 101 tons). The engineering and R&D departments are located in Italy, South Korea, and China and collaborate to combine know-how, technology, and development capabilities. The engineering departments in each production plant have specific knowledge about locally produced components, while the headquarters of 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 for proper winding. 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 the correct chain tension. The correct sag for all conventional tracks is about 50mm (+-5mm). For example, a track on 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 the suggested sag of 50 mm will have a tension value of 362 kg. An excessively tight track increases pressure, causing more wear on track bushings when in contact with the drive sprocket teeth and in the chain-tensioning wheel-roller contact. The tread hardness equal to or greater than the chain links, drive rollers, and support rollers ensures impact resistance and balanced durability. Material type: SCMn3A, hardening 50-55 HRC. Lifetime lubrication to minimize maintenance.

Functionality of ITR Tensioning Wheels

The function of a tensioning wheel is to properly tension and guide the track chain, ensuring its correct winding. The tensioning wheel and adjuster work together to maintain a specified degree of track tension. Efficient chain tension is a key factor affecting undercarriage durability. The optimal deflection for conventional tracks is about 50mm (+-5mm). For example, a track in an 80-horsepower machine with a 12mm deflection will have a tension of 2540 kg when measured at the track adjuster. Meanwhile, the same machine, with the suggested 50mm deflection, will have a tension of 362 kg. An overly tight track increases pressure, leading to greater wear on track bushings and drive wheel teeth, as well as contact between the chain, tensioning wheel, and rollers. Appropriate tread hardness, equal to or greater than the chain links and running and supporting rollers, ensures impact resistance and balanced durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication minimizes maintenance throughout its service life.
