Description
WG9725478228 steering gear box is the core assembly of the steering system for Sinotruk Howo heavy trucks. It converts the rotary motion from the steering wheel into swing power to drive the steering linkage, realizing the deflection of front wheels and controlling vehicle travel direction. The gear box housing adopts high-strength cast alloy, internal worm and sector shaft are forged from premium alloy steel with heat treatment and precision grinding. It features high load capacity, low backlash, stable transmission and good fatigue resistance. It can bear heavy load impact and frequent steering operation under mountainous and bumpy road conditions. Each steering gear box undergoes strict sealing test, steering torque test and durability fatigue test before delivery, effectively preventing oil leakage, excessive steering play and internal gear wear. It is an essential spare part for steering system overhaul. We maintain sufficient inventory and stable bulk supply for repair workshops, fleet operators, auto spare parts dealers and global cross-border export customers.
