427-70-13611, PC1260 bucket side guard plate, side protector, PC1250 mining bucket wear parts, matched with PC1250, PC2000 bucket. WS300 lip protector, ES66972 corner guard
The 427-70-13611 side protector is the original factory standard side wear-resistant protective part for Komatsu Hensley PC1250 series mining buckets. It is installed on both side walls of the bucket, bearing lateral stone friction, impact and extrusion during heavy-load mining and excavation operations. It effectively protects the bucket side plate from rapid abrasive wear and edge cracking, stabilizes the overall structural strength of the bucket, and avoids bucket body deformation caused by long-term lateral impact load.
Manufactured from high-purity alloy steel with integral secondary heat treatment, the side protector features uniform organizational structure, stable hardness and excellent lateral impact resistance. The mounting hole position, plate thickness and edge radian fully match the original PC1250 bucket benchmark size, achieving zero-gap assembly with side adapters and corner guards. It forms a complete enclosed wear-resistant protection system with all matching parts of the PC1250 system, greatly improving the overall durability and mining operation stability of the PC1250 bucket.
