131902020001A Guide wheel Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 131902020001A idler wheel is a core guiding component for tracked engineering machinery, compatible with tracked equipment such as excavators and rotary drilling rigs. Installed at the front of the chassis, it works in conjunction with the tensioning device to precisely guide the cyclical movement of the tracks, constrain lateral track sway, correct the travel trajectory, prevent track deviation and unilateral force application, improve the stability of the equipment during straight-line travel, turning, and climbing, and reduce abnormal track wear.
This product is made of high-strength alloy casting and hardened by quenching, resulting in a hard, wear-resistant, impact-resistant, and pressure-resistant wheel body. Combined with a high-precision sealing structure, it effectively prevents mud, water, and dust from entering. Under complex heavy-load conditions, old guide wheels are prone to wear, seal failure, and mud buildup, leading to problems such as misalignment, chain slippage, and abnormal noise. This product features original factory precision molding, standard hole positions, and excellent coaxiality, allowing for non-destructive replacement of old parts. It is suitable for routine maintenance, fault repair, and bulk stocking, stabilizing chassis performance and reducing operating costs.
