Heavy-Duty Slides for a US Tool Cabinet Maker

We proposed a 76 mm wide ball-bearing slide rated at 220 kg per pair, with a reinforced ball retainer and a zinc-plated + black passivated finish. The retainer was redesigned with thicker gauge steel and additional bend ribs to prevent the spread that had caused the field failures.

To address the cosmetic requirement we added a topcoat conversion layer after plating, then ran a 48-hour neutral salt-spray test on production samples. The hold-in detent was tuned to 12 N ± 2 N so drawers stay closed on tilted service trucks but are still easy to open.

We aligned the drilling pattern with the customer's existing cabinet side extrusion and supplied a jig drawing so their assembly team did not need to retool the line.
