Hand-fabricated aftermarket feed chain built to better than OEM specifications for Diamond Z grinders. Constructed from A572 Gr 50 steel flights, 1018 steel pins, and DOM hinge tubing, then jig-assembled and verified for consistent fit and longevity. Machine Fitment: All Diamond Z 5500 Series Grinders Flight Count: 96 Materials & Construction Flights: A572 Grade 50 steel — minimum yield strength 50,000 psi, selected for wear resistance and structural integrity under repeated impact loading Pins: 1018 steel — carburized/case-hardenable low-carbon steel chosen for consistent shear strength and dimensional stability Hinges: Drawn Over Mandrel (DOM) tubing — tight ID/OD tolerance and uniform wall thickness for consistent articulation and reduced wear at the pivot point Fabrication Process Each chain is hand-assembled on a fixed jig to hold flight spacing, pin alignment, and hinge positioning to consistent tolerances across the full chain length. Every completed chain is quality-checked prior to shipment to verify dimensional accuracy and joint fit.
