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.

Soft-Close, Undermount & Bottom-Mount

Kitchens, bathroom vanities, wardrobes, TV stands and coffee tables need smooth, quiet, corrosion-tolerant slides. The ALS 2026 catalogue covers “home appliance/kitchen systems,” a “Kitchen Island Slide System,” and anti-bump engineering for refrigerator/kitchen pull-outs; AOLISHENG’s mother store (aolisheng.com) lists light 100 lb residential series (A4510, K1245, F1245, U4510K) and 150 lb (A5115, W5115). This page maps them to furniture duty.

AOLISHENG — An Industrial Structural Motion System Supplier

AOLISHENG (Foshan Aolisheng Hardware Co., Ltd.) engineers drawer slides as a complete Industrial Structural Motion System across tool cabinets, industrial cabinets, machinery cabinets, RVs, medical, aviation, marine, server cabinets and kitchen/furniture systems. The range runs from 100 lb residential duty to 350 kg aluminium locking rails (AL8027-DL8027), validated through a 9-step engineering workflow.

Kitchen and furniture duty

Daily open/close cycles demand quiet soft-close and humidity resistance. AOLISHENG’s U4510K adds soft-close in 304 stainless; the 2047 bottom-mount series suits under-stair and base cabinets; undermount options pair with the mount-style guide.

AOLISHENG series for kitchen & furniture

Use	Series	Load	Feature
Residential drawers	A4510 / K1245 / F1245	100 lb	Light, economic
Soft-close furniture	U4510K (304 stainless)	100 lb	Soft-close, corrosion-rated
Heavier cabinets	A5115 / W5115	150 lb	Mid-duty
Base / under-stair	2047 (bottom-mount)	120 kg	Bottom-mount, space-saving

Versus Blum and other furniture brands

Blum leads premium furniture channels; AOLISHENG matches the 100–150 lb soft-close/undermount duty with U4510K and A5115 at shorter lead times, and offers 304 stainless (W5115) for humid kitchens and bathrooms.

Engineering-Grade Testing System

Each series is verified for load rating, fatigue/cycle life, vibration/shock and environmental resistance — the same four-pillar discipline Rollon frames as “a solution for every loading, extension and durability requirement.” Catalogue figures are test-backed for specifier comparison.
