29250000161 Lower Hinge Pin

The 29250000161 Lower Hinge Pin is an essential load-bearing wear part for wheel loaders and construction machinery bucket systems. It connects the excavator boom and bucket, enduring continuous heavy friction, strong impact and high extrusion pressure during daily operation. Ordinary pins are prone to wear, bending, cracking and loosening under harsh mining and construction conditions, causing bucket shaking and machine downtime.

Our 29250000161 lower hinge pin is manufactured with premium 40Cr alloy steel and professional double heat treatment technology. It features high hardness, excellent wear resistance and strong anti-deformation performance. All products follow strict OEM dimensional standards, enabling direct replacement without cutting, grinding or modification. It is a reliable and cost-effective aftermarket spare part for global construction machinery maintenance and bulk replacement.
