XA12038ST
Shaft Yoke
SAF-Holland

Designed as a high-strength yoke shaft element, this component plays a critical role in transmitting torque and aligning the drive interface within SAF-Holland yoke assemblies. Its precision fit ensures minimal play between mating components, promoting smooth rotation, accurate shaft alignment, and reduced wear under cyclic loading. The yoke shaft supports safe engagement during steering, articulation, and load transfer in heavy-duty trailer systems, contributing to long-term reliability in demanding applications. It is associated with VMRS code 059-001-136 and belongs to the yoke/shaft family in the 42818 category, signaling compatibility with SAE-standard yoke interfaces and SAF-Holland drive train components. Cross-functional use includes anchoring or bridging connections in fifth-wheel and coupling configurations where exact alignment is essential for consistent pin engagement and load distribution. This part is well-suited for both field replacements and OEM refurbishment projects, delivering dependable performance in suspension, hitch, and kingpin assemblies across various trailer platforms and operating environments.
