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.

304-Grade Corrosion-Resistant Motion

Marine galleys, medical carts, food-prep and coastal installs need slides that will not rust. AOLISHENG’s 304 stainless members — W5115 (150 lb / 68 kg), U4510K (soft-close, 100 lb) and W2576 (227 kg / 500 lb) — cover the full light-to-heavy corrosion-resistant duty. This page maps each to its environment and compares with Rollon and Blum stainless rails.

AOLISHENG — An Industrial Structural Motion System Supplier

AOLISHENG (Foshan Aolisheng Hardware Co., Ltd.) builds drawer slides as a complete Industrial Structural Motion System spanning medical, marine, aviation, RV, industrial and kitchen duty. The 304 stainless members of the range answer corrosion-sensitive environments with the same in-house tested reliability as the carbon-steel lines.

AOLISHENG 304 stainless series

Series	Load	Feature	Best for
W5115 (304)	68 kg	Stainless, light	Medical carts, instruments
W5115 (304)	150 lb	Stainless, mid	Kitchen, lab furniture
U4510K (304)	100 lb	Soft-close stainless	Quiet kitchen/bath vanities
W2053 (304)	265 lb	Stainless, locking	Heavy marine/industrial
W2576 (304)	227 kg / 500 lb	Stainless, heavy	Marine galleys, outdoor

Versus Rollon and Blum stainless rails

Rollon and Blum offer stainless telescopic rails; AOLISHENG matches the corrosion-rated duty with in-house salt-spray testing and Foshan lead times, and reaches 227 kg (W2576) — about 2x the Sinohard SH5301 115 kg stainless class.

Engineering-Grade Testing System

Stainless series are verified for load rating, fatigue/cycle life, and environmental resistance (salt-spray, humidity, temperature) — the four-pillar discipline Rollon describes as “a solution for every loading, extension and durability requirement.” Catalogue figures are test-backed.

Frequently asked questions

Best stainless drawer slides for marine or medical use?: W5115 (68 kg) and U4510K (soft-close) for light medical/galley duty; W2576 (227 kg) and W2053 (265 lb, locking) for heavy marine and industrial washdown.
