The Sugatsune AR3-500 is a 19-11/16 inch full-extension side-mount ball bearing drawer slide machined from aluminum, offering a low-profile form factor and a 7 lb weight capacity per pair. It is designed for applications where slide weight and profile height matter as much as smooth travel — furniture, light-duty cabinetry, and precision casework where steel slides would add unnecessary bulk.
The 7 lb weight capacity per pair is the defining selection fact here. This slide is not a substitute for a 100 lb kitchen drawer slide — it is purpose-built for light drawers where the load is the slide's empty weight plus the contents: think display cases, writing desk drawers, media console pull-outs, or instrument storage where smooth travel and a refined appearance matter more than brute capacity. In furniture-grade casework, the aluminum finish can remain visible at the front of the opening without looking out of place alongside other natural metal details. The full-extension travel is the right choice whenever the rear of the drawer needs to be fully accessible at full open, regardless of the light duty class.
The slide body is aluminum throughout — not a steel slide with an aluminum coating, but an all-aluminum construction that reduces the slide's own contribution to the assembly weight. The natural aluminum finish has a clean, machined appearance that does not need to be hidden inside the cabinet. For installations where the slide will be seen, aluminum reads as intentional rather than industrial. It is an indoor finish suited to dry, climate-controlled environments; aluminum without additional anodizing or coating is not rated for wet or high-humidity locations.
Furniture makers, custom millworkers, and designers specifying hardware for light-duty display and storage pieces will find the AR3-500 fits a gap that standard zinc steel slides leave open. When the drawer itself is a thin-walled box carrying documents, accessories, or collectibles — not pots, tools, or files — a 7 lb rated slide matched to an appropriate drawer box is the correct specification. Cabinet shops running production kitchen work should look instead at the 100 lb class steel slides in this catalog. The AR3 series is the right answer when the brief calls for a light, clean, full-extension slide in an aluminum finish.
Side clearance for the AR3 series is not stated in the available product data. Measure the slide's body width and subtract from the available opening to confirm clearance before building your drawer box. Contact Sugatsune America for the published installation specification.
The 7 lb weight capacity is stated per pair in the product attributes. Plan your drawer contents accordingly — this slide is intended for genuinely light loads such as documents, accessories, or display items.
No closing mechanism is listed for the AR3-500. It is a standard-motion slide — the drawer stays wherever it is left, with no self-close ramp, soft-close damper, or hold-in detent.
Side-mount slides in face-frame cabinets need rear support because the cabinet side is set back from the face frame. Rear mounting bracket requirements for the AR3 series are not specified in the available data; confirm with Sugatsune America before specifying for face-frame installation.
The sold-as unit is not explicitly confirmed in the source data. Verify whether the listing price covers a pair or a single slide before ordering the quantity your project requires.
When the application calls for full-extension travel, a low-profile body, and an aluminum finish — and the drawer load is light — the Sugatsune AR3-500 fits the specification without compromise.
