• 

Priority Valve is an important control valve for loader hydraulic system. It prioritizes hydraulic oil flow for steering circuit to guarantee quick steering response, and distributes residual flow to boom and bucket cylinders for combined movements, preventing heavy- load stiff or failed steering. Cast- iron valve body with precision spool assembly. Compatible with mainstream 5- ton wheel loaders, for hydraulic system repair replacement and used- loader refurbishment export, suitable for heavy- loading conditions in mines and stock yards.

• 

Skeleton oil seal is critical sealing wearing part for loader gearbox, wheel hub and drive shaft. Built- in metal skeleton supports sealing lip to hold rotating shaft tightly. It prevents lubricating oil leakage and blocks sand, du st and muddy water from entering cavity to protect bearings and gears. Made of fluororubber, it features excellent oil resistance, high- temperature resistance and anti- aging performance. Compatible with mainstream 5- ton wheel loaders, widely used for equipment repair and used- loaderrefurbishment export, suitable for dusty and muddy heavy- duty mine & construction- site conditions.

This step- shoulder hinge bushing is a critical wearing component for wheel loader boom and bucket hinge joints. Made of high- strength alloy steel with step- shoulder locating structure, it serves as the sleeve between hinge pin and frame. The shoulder acts as positioning stop to prevent axial displacement during heavy- load impact operations. It bears large extrusion and impact load during digging, lifting and dumping cycles. Suitable for equipment maintenance and second- hand loader refurbishment export, performs reliably in harsh mine and stock- yard heavy- load conditions.
