Heavy Duty Slide Base, KOMP
SAF-Holland

Incorporating a fifth wheel family design, this heavy duty slide base is tailored for high-load towing systems requiring precise articulation and long service life. The product attribute family designation emphasizes compatibility with standard fifth wheel components, delivering predictable fit and reliable coupling behavior across fleets that demand uniform performance. With a robust construction and purpose-built for high-cycle operation, the assembly maintains alignment during dynamic maneuvers, reducing wear on mating components and improving cab-to-trailer coupling stability. VMRS code 059-001-003 situates it within the fifth wheel slide base subset, reinforcing its role as a critical interface between tractor and trailer. Applications span long-haul fleets, regional transport, and vocational operations where efficient hitch engagement, reduced maintenance intervals, and consistent pull strength are essential. Key benefits include smoother pin engagement, minimized binding under load, and dependable return-to-lock during decoupling. Installation considerations include verifying mounting patterns, ensuring clean sliding surfaces, and inspecting for wear on rails and mounting hardware to sustain performance over thousands of cycles. Category context: heavy duty slide bases within the fifth wheel family.
