AOLISHENG 7120 71 mm Heavy-Duty Drawer Slides: Specs, Dimensions & Applications
AOLISHENG 7120 at a Glance
The AOLISHENG 7120 is a 71 mm-wide heavy-duty side-mount drawer slide built for demanding storage: industrial control cabinets, tool boxes, RV and truck storage, medical carts and heavy furniture drawers. Each pair is rated for 150 kg (≈330 lb) and uses a full-extension, ball-bearing mechanism in cold-rolled Q235 steel with blue zinc plating.

Construction & Materials
The 7120 profile is formed from Q235 cold-rolled steel with a material thickness of 2.0 × 2.0 × 2.0 mm across the three members, which gives the rail its rigidity at a 71 mm width. The surface is blue zinc plated for everyday corrosion resistance in dry and lightly humid indoor and vehicle environments. Installation thickness is 18.5 ± 0.5 mm, so the slide seats into standard 18–19 mm carcass and drawer-box panels without modification.
Load Capacity — What 150 kg (≈330 lb) Means
The 150 kg figure is a per-pair rating: it is the load both slides together support when mounted to a square, rigid carcass. In practice that covers fully loaded tool chests, server and instrumentation drawers, and stacked parts bins. If your drawers approach that weight, pair the 7120 with reinforced cabinet sides and confirm the fixing screws bite into solid material. For heavier needs, step up to the AOLISHENG 7625 (220 kg); for lighter residential drawers the 5115 (68 kg) or 2053 (120 kg) are slimmer and lower cost.
Full Extension & Ball-Bearing Action
Full extension means the drawer clears the cabinet completely, so you reach items at the back without stretching. The ball-bearing race gives a smooth, even pull with no binding, and the slide holds its line under side load better than roller or polymer channels. The 7120 is supplied as a fixed-length pair; choose the length that matches your drawer depth (see below).
Side-Mount Installation
As a side-mount slide, the 7120 fixes to the carcass side and the drawer-box side. Fix the cabinet member first using the stamped drilling marks, square it to the front edge, then attach the drawer member and test full travel before loading. Keep both sides parallel and use the full screw pattern — the 150 kg rating assumes all fixings are engaged. For a bottom-mount stair-storage option, see the AOLISHENG 2047.
Where the 7120 Belongs
- Industrial control & electrical cabinets — deep drawers for manuals, spares and test gear.
- Tool boxes & workbenches — the 330 lb per-pair rating suits heavy socket and power-tool storage.
- RV, van & truck storage — rigid full-extension travel that survives vibration.
- Medical & lab carts — smooth, repeatable access to instruments.
- Retail fixtures & heavy furniture — where a 71 mm heavy-duty profile is the right fit.
For marine, wash-down or coastal use where zinc plating is not enough, move to the 304 stainless W2576 (500 lb) or the stainless builds of the 2053 / 5115 series.

Picking the Right Length (A2071)
The 7120 family is offered as the A2071 — a 330 lb, full-extension, ball-bearing, side-mount pair aimed at industrial and DIY tool storage. Measure the drawer depth (inside front to back), then choose a slide length equal to or slightly shorter than that depth; the slide cannot extend beyond the drawer box. Lengths follow the standard AOLISHENG step series, and the A2071 ships as a 1-pair kit.
