What is the difference between side mount and undermount drawer slides?

Side mount slides fix to the drawer sides and cabinet walls — easy to fit and tolerant of cabinet tolerances. Undermount slides sit beneath the drawer box, hide the hardware for a cleaner look, and need a compatible drawer box with the right reveal. AOLISHENG builds both: side-mount heavy-duty series (2053 / 2576 / 7625) and undermount soft-close series (MK316 / U4510K).

What does full extension mean compared with 3/4 extension?

3/4 extension leaves the back of the drawer still inside the cabinet; full extension brings the whole drawer clear of the cabinet face so you can reach the back corner. Most AOLISHENG heavy-duty and soft-close series are full extension.

How do I choose the load rating for a drawer slide?

Add the heaviest realistic contents, then add 25–30% headroom so the slide is not run at 100% of its rating every day. AOLISHENG ratings run from 100 lb (U1245) through 265 lb (2053 family), 330 lb (2071), 500 lb (2576 family) up to 770 lb (AQ7625K3 twin-slide).

What are soft-close drawer slides and when do I need them?

Soft-close slides use a damper that pulls the drawer shut in the last few centimetres, preventing slamming. They are most noticeable on kitchen and bathroom cabinetry and also reduce the shock load that gradually loosens a carcass. AOLISHENG soft-close options include K2053, U4510K and MK316.

Are stainless steel slides worth it for outdoor or marine use?

Yes — whenever the slide is exposed to weather, salt air, humidity or frequent wash-down (outdoor kitchens, marine galleys, food-prep, coastal installs). AOLISHENG stainless options include W2053, W2576, W5115 and U4510K.

Which AOLISHENG series number maps to which spec?

The stamped codes read: 1245 = 100 lb stainless side mount; 4510 = 100 lb stainless; 5115 = 150 lb; 2053 = 265 lb; 2071 = 330 lb; 2576 = 500 lb; 7625 = 770 lb twin-slide. Remove the drawer and read the code on the inner rail, or send a photo and AOLISHENG will match it.

Can heavy-duty slides be used in RVs, trucks and vehicles?

Yes, with a locking slide so the drawer cannot slide open under braking or cornering. Use locking series such as D5115, D2053 or D7625 for any moving-vehicle storage.

Smooth, Quiet Drawer Slides for Medical Carts and Healthcare Furniture: A B2B Case Study

The B2B challenge: quiet, clean, and reliable motion in healthcare

A medical furniture OEM supplying hospitals and clinics needed drawer motion that matched the expectations of healthcare environments: quiet enough for patient areas, smooth enough for one-handed operation, and corrosion-resistant enough for frequent wipe-downs. Standard slides were too noisy, showed wear quickly, and lacked the soft-close feel expected in premium medical carts.

Why medical-grade slides differ

Low noise: ball-bearing action and soft-close damping keep carts quiet in patient corridors.
Corrosion resistance: disinfectants and saline solutions attack plated finishes.
Smooth feel: drawers must open reliably even when loaded with instruments and supplies.

The AOLISHENG solution: stainless and soft-close series matched to cart load

We matched the cart family to three slide families, covering equipment weight and aesthetic requirements:

Series	Load rating	Type	Lock / close	Best for
W2576	500 lb / pair	304 stainless, full extension	Non-locking	Heavy equipment carts & procedure trolleys
U4510K	100 lb / pair	304 stainless, soft-close	Soft-close	General cabinetry & supply carts
MK316	80 lb / pair	Undermount, soft-close	Soft-close	Sleek nurse stations & reception furniture
A5115	150 lb / pair	Heavy-duty ball bearing	Non-locking	Light carts and accessory trays

Results the OEM reported

Noise complaints from cart motion fell sharply after switching to soft-close and precision ball-bearing lines.
The 304 stainless slides held up to daily disinfection cycles where plated slides had corroded.
Undermount options gave high-end carts the clean, hardware-free look specifiers wanted.

Why B2B buyers choose AOLISHENG for healthcare

A single supplier covers load ratings from 80 lb to 500 lb, in both visible side-mount and hidden undermount form factors, with stainless options for demanding hygiene protocols. That simplifies BOM management and keeps lead times predictable.
