XA-A824
Slide Base Assembly
SAF-Holland

This base component serves as the essential foundation for a sliding mechanism, delivering a rigid, stable platform that supports smooth motion and predictable engagement with the mating kingpin interface. Although details are not listed for this specific model, the base is engineered to endure high cycle loads, resist deformation under heavy braking and acceleration, and maintain precise alignment with rail guides. The VMRS designation 059-001-045 positions it within the standardized family governing slide base and bracket systems, ensuring compatibility with common mounting patterns and shareable maintenance practices across fleets. In practical terms, the assembly minimizes binding and stiction as the platform transitions between retracted and extended states, reducing operator effort during coupling and uncoupling. It also contributes to longer service life for sliding components by maintaining consistent clearances and load paths, thereby preserving the integrity of the hitch interface under repetitive dynamic loads. As part of a broader trailer coupling subsystem, the base supports straightforward interchangeability and rapid field replacement when wear limits are reached, with category context highlighting its integral role in the slide-based hitch architecture.
