— Product Model: 131902020057A001
— Product Name: Guide Wheel Bracket
— Product Type: Original equipment manufacturer (OEM) parts for construction machinery, including four-wheel and one-track systems, idler wheel supports, and structural mounting base accessories.
The 131902020057A001 idler wheel bracket is a core component of tracked engineering machinery chassis, serving as a dedicated mounting base for the idler wheel assembly. Its main functions include supporting and fixing the idler wheel and tensioning components, precisely limiting the movement of the walking structure, distributing impact loads from walking, turning, and climbing, constraining the position of the idler wheel to prevent loosening and displacement of components, regulating the track’s running trajectory, and ensuring balanced force distribution and stable operation of the walking system.
This product is made of high-strength cast steel in one piece, with thick walls and sufficient rigidity. It is resistant to torsion, compression, and fatigue deformation, making it suitable for heavy-duty and bumpy working conditions such as mining and earthmoving. Long-term impact from equipment movement can easily cause deformation and cracking of old brackets, wear of holes, and loosening of fixation, leading to idler wheel misalignment, track deviation, walking vibration, chain slippage and abnormal noise, and accelerated wear of chassis components. This product features precise original factory molding and standard hole positions, allowing for non-destructive replacement of old parts. It is suitable for routine maintenance and bulk stocking, effectively stabilizing the chassis structure and reducing operation and maintenance losses.
