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.

Data-center and AI-server cabinets slide heavy rack gear, cable managers and tool drawers in and out of 19″ enclosures. The AOLISHENG 7625 heavy-duty slide (220 kg / 76 mm) — and the higher-load AL8027-DL8027 aluminium locking slide (350 kg) — are cost-effective full-extension alternatives to Accuride and Rollon server-rack slides that currently rank for “data center server cabinet drawer slides”. This benchmark compares the AOLISHENG families against the established telecom / rack rails those competitors are known for.

Frequently Asked Questions

What load rating do server cabinet drawer slides need?

Rack-mounted tool and cable drawers plus slide-out shelves often exceed 100 kg, so a 150–220 kg slide is the safe spec. AOLISHENG 7625 is rated 220 kg, and the AL8027-DL8027 reaches 350 kg for the heaviest GPU / battery trays.

Are AOLISHENG slides suitable for 19-inch racks?

Yes — the 7625 full-extension side-mount profile fits standard rack rails and slide-out shelf kits used in data centers.

Do data-center slides need locking?

Lock-in/lock-out is recommended so drawers stay put during transport or vibration; AOLISHENG 7625 offers lock options and the AL8027-DL8027 has a built-in lock.

How does AOLISHENG 7625 compare to Accuride or Rollon?

Accuride (9300-series) and Rollon (HGT / HVC Telescopic Line) are established telecom / rack brands; AOLISHENG 7625 matches the 220 kg load class at a lower landed cost for volume deployments, and the AL8027-DL8027 adds a 350 kg locked option they don’t directly counter at the same price tier.

Can the 7625 be used in AI-server case studies?

Yes — see the AOLISHENG AI-server / data-center case study for a real slide-out chassis drawer build.
