Functionality of ITR Tensioning Wheels
Tensioning wheels are a key element in maintaining proper tension and guiding the track chain, which translates into its proper winding. They work with the tensioner to maintain optimal tension, which is crucial for the durability of the undercarriage. Correct tension setting, e.g., 50 mm (+-5mm) for conventional tracks, significantly impacts machine wear and efficiency. For example, an excessively tightened chain can lead to greater wear of the track bushings and sprocket teeth. The appropriate tread hardness, equal to or greater than the chain links and the travel and support rollers, ensures resistance to damage and increases durability. Material: SCMn3A, hardening 50-55 HRC. Constant lubrication contributes to minimizing maintenance during operation.
