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.

Heavy-Duty Drawer Slides for AI Servers & Data-Center Cabinets: Vibration-Stable Case Study

Heavy-Duty Drawer Slides for AI Servers & Data-Center Cabinets

AOLISHENG develops Industrial Structural Motion System solutions for high-density infrastructure — the same engineering discipline behind the Cloud / AI Servers and server & communication cabinets applications named in the ALS 2026 catalogue. Modern AI-server chassis carry dense GPU banks that weigh far more than a traditional 1U/2U tray, and racks are serviced by pulling drawers or slide-out trays in cramped, vibration-prone data-center aisles. AOLISHENG supplies full-extension heavy-duty drawer slides rated from 120 kg up to 350 kg per pair for GPU chassis, storage trays and service drawers — with the load headroom and rigid travel AI-infrastructure OEMs need. The families below are the ones most specified for server and data-center cabinets, with dimensions from the ALS 2026 catalogue.

Server & data-center slide families (per ALS 2026 catalogue)

Series	Load	Width	Material / note
7625	220 kg (≈485 lb)	76 mm	Q235 cold-rolled / 304 stainless, 8–80″, blue-zinc; bidirectional / double-row / stacked variants
2053	120 kg (≈265 lb)	53 mm	Steel / 304 stainless, 10–80″
7120	150 kg (≈330 lb)	71 mm	Q235 cold-rolled steel, 10–40″
AL8027-DL8027	350 kg (≈771 lb)	80 mm	Aluminium heavy-duty locking slide — highest-load option for dense GPU / battery trays (per ALS 2026 catalogue)

Why slide choice matters in a rack

GPU tray weight — high-density accelerators push trays toward the 150–220 kg range; the 7625 carries them with margin, and the AL8027-DL8027 reaches 350 kg for battery / liquid-cooling trays.
Full access for service — full-extension travel lets technicians reach the back of a tray without un-racking.
Stable, low-deflection travel — rigid ball-bearing travel keeps a heavy tray from sagging mid-pull.
Optional stainless — 304 stainless builds of the 7625 and 2053 suit cleanroom or corrosion-sensitive environments.
Lock-in / lock-out — available on the heavy-duty and AL8027 families so trays stay put during transport or vibration.

Engineering-grade reliability (per ALS 2026 catalogue)

AOLISHENG qualifies its structural-motion products through an engineering test system covering load-bearing, fatigue, vibration and environmental testing, exposing structural problems under real loads and conditions before release. For data-center buyers this means the 7625 / AL8027 families are validated for the cyclic pull-out, sustained load and shock loads a rack tray sees across its service life — not just a static catalog rating.

Proven in the field

An AI-server OEM standardized on AOLISHENG 7625 slides for GPU service trays, gaining the load headroom to support heavier accelerator skus without re-qualifying the cabinet. Related: the RV locking case study shows the same heavy-duty family used in a mobile environment.

Server slides vs Rollon- and Accuride-class rails

Rollon (Telescopic Line, HGT / HVC series) and Accuride (9300-series telco / rack rails) are established premium brands for aerospace, rail and high-end server cabinets at top-tier price points. AOLISHENG’s 7625 delivers 220 kg full-extension side-mount behaviour in steel or 304 stainless at a mid-market cost, and the AL8027-DL8027 reaches 350 kg with a built-in lock — the practical choice for server and data-center cabinet manufacturers standardising on heavy, serviceable trays at volume.

See the drawer-slide type comparison, the buyer’s guide, the AOLISHENG vs Rollon guide, or browse B2B case studies. Related series: 7625 (220 kg), 2053 (120 kg), 5115 (68 kg).

Frequently Asked Questions

What drawer slides hold a heavy GPU server tray?

Use a heavy-duty full-extension slide rated with margin above the loaded tray weight — the 7625 at 220 kg (≈485 lb) per pair covers dense accelerator trays, and the AL8027-DL8027 reaches 350 kg for battery / liquid-cooling trays.

Can drawer slides be stainless for data centers?

Yes — 304 stainless builds of the 7625 and 2053 families suit cleanroom or corrosion-sensitive installs.

Do these slides give full access to a tray?

Full-extension side-mount travel lets a technician pull a tray completely out for service without un-racking the chassis.

What load headroom should I plan for a 19-inch rack drawer?

Size to the heaviest realistic tray plus 25–30% headroom; most AI GPU trays land in the 150–220 kg range, so a 220 kg slide plus the 350 kg AL8027 option covers future skus.

Do data-center slides need locking?

Lock-in / lock-out is recommended so drawers stay put during transport or vibration; the 7625 and AL8027-DL8027 families offer lock options.
