The Sugatsune ESR-6 Series is a 28 inch full-extension side-mount ball bearing drawer slide manufactured from 304 stainless steel, rated 99 lb per pair. Where ordinary zinc-finished slides corrode, pit, or stain, the ESR-6 holds up — making it the right choice when the installation is a commercial kitchen, food-prep station, lab, marine galley, or anywhere regular cleaning is part of the routine.
The ESR-6 is specified for environments that rule out zinc-plated steel: commercial food-prep and galley drawers that see daily sanitizing spray, laboratory casework subject to chemical splash, marine cabinetry where salt air accelerates corrosion, and any installation where appearance standards require hardware that will not rust-streak a white interior over time. Full extension brings the whole drawer out to the cabinet opening, which matters in a professional kitchen where speed and access to the back of the drawer are part of the workflow. A 28 inch slide suits deeper drawers — utility, prep, and storage boxes where a shorter slide would leave rear contents out of easy reach.
The SAP description confirms 304 stainless steel — a chromium-nickel alloy with strong resistance to oxidation and most cleaning agents used in food-service and laboratory settings. Unlike zinc plating, which is a surface coating that can be compromised by abrasion or prolonged moisture exposure, 304 stainless is corrosion-resistant through the full thickness of the steel. Ball bearings run in full-length raceways machined into the stainless members, maintaining smooth travel across the slide's service life. Because this is standard-motion, there are no damper components or springs to service or replace.
Designers and specifiers who work on commercial kitchens, lab furniture, healthcare casework, or marine interiors often have a corrosion-resistance requirement written into the project. The ESR-6's 304 stainless construction satisfies that requirement in a side-mount ball bearing format that installs exactly like a conventional slide — no new tooling, no unusual clearances, no special fasteners. Cabinet shops building specialty casework in these verticals can run this slide through a standard production process. The standard-motion behavior is intentional for these applications: self-close and soft-close mechanisms add components that may not be appropriate in washdown environments, and keeping the drawer exactly where it is placed is often preferable in a professional work setting.
304 stainless offers good general corrosion resistance, including in humid and salt-air environments typical of marine interiors. For direct saltwater spray or submerged applications, 316 stainless is generally the preferred grade. Confirm the exposure conditions with the project specification before installing.
The 28 inch figure is the closed slide length. Because the ESR-6 is full extension, the drawer member travels approximately the full slide length, bringing the entire drawer out to the cabinet face. Slide length and travel are not the same spec on partial-extension slides, but on a full-extension model they are effectively equal.
No. The ESR-6 is a standard-motion slide — no spring, no damper. The drawer stays wherever it is pushed, which is the expected behavior in professional and laboratory environments where controlled placement matters.
Side clearance for this series is not stated in the available source data. The standard for side-mount ball bearing slides in this segment is nominally 1/2 inch per side, but confirm the ESR-6's specific requirement with Sugatsune's published installation data before building the drawer box.
The sold-as unit is not explicitly stated in the source data. Order one pair per drawer and confirm the unit with the product listing before placing a volume order.
When the project calls for hardware that holds up to cleaning, moisture, and demanding use over the long term, the ESR-6 delivers full-extension ball bearing performance in a material built for it — without compromising on the installation simplicity a production shop expects.
