XA-101-OAS
Top Plate 5th Wheel
SAF-Holland

This top plate serves as the primary bearing surface and load distribution interface in fifth wheel assemblies, distributing vehicle and trailer forces across a broad contact area to minimize localized wear. VMRS code 059-001-001 and category 42763 place it squarely in the main mating surface group that defines the towing interface. The surface finish, hardness, and wear-resistant treatment are optimized for long service life under repeated coupling cycles, while maintaining alignment accuracy between tractor and trailer. Its geometry supports even load transfer, reduces peak stress concentrations, and helps maintain proper clearance with adjacent locking components. The plate’s compatibility with SAF-Holland top plate configurations ensures straightforward installation and interchangeability, supporting fleet maintenance programs and aftermarket replacements. Expect predictable performance in terms of lock integrity, hitch stability, and retention under dynamic loads from potholes, braking, and high-speed maneuvers. No cross references are listed; category 42763 positioning emphasizes its function as the foundational surface for safe, reliable towing operations.
