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.

Precision Drawer Slides for Robotics & Automation Equipment

AOLISHENG is an Industrial Structural Motion System design brand — 17 years building full-extension slides for tool cabinets, industrial cabinets, machinery, RVs, drones, new-energy equipment and warehouse systems, exported to nearly 100 countries. For robotics and automation builders, that means slides engineered the way a motion-system supplier engineers them: rated loads verified by load, fatigue, vibration and environmental testing, consistent travel through millions of cycles, and the rigidity automation cells demand. The families below are the ones most specified for robotics, with dimensions from the ALS 2026 catalogue.

Robotics & automation slide families (per ALS 2026 catalogue)

Series	Load	Width	Material / note
7625	220 kg (≈485 lb)	76 mm	Q235 / 304 stainless · 8–80″ · bidirectional, dual-row & dual-overlay build options
DQ7625 / DW7625	220 kg (≈485 lb)	76 mm	Single-side locking variant of 7625 for vibration-sensitive cells
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″
5115	68 kg (≈150 lb)	51 mm	Hook, anti-tip & locking (DQ/KQ) variants for light service drawers
AL8027 / DL8027	350 kg (≈770 lb)	80 mm	Aluminium 7005 (CNC+), anodic oxidation · 12–68″ · DL8027 = locking heavy-duty

Where automation slides are used

Rollon frames telescopic rails around application need — “a solution for every loading, extension and durability requirement.” AOLISHENG builds to the same logic, with series matched to the robotics duty cycle:

Tool-changer & end-effector drawers – rigid, low-deflection travel under payload, rated to 50,000+ cycles.
Control & electrical cabinets – full-extension access to breakers, drives and terminations inside automation enclosures.
Test & fixture trays – repeatable pull-out that holds calibration through service cycles.
AGV / AMR service modules – battery, tooling and parts bays that slide out under repeated cycle loads.
Machine-tending drawers – component and consumable access at the robot cell, with locking for safe motion.
Robotics-cell service panels – heavy 8027 (350 kg) rails for large access panels and guarded doors.

Engineering-grade reliability (full-process motion system)

Like the premium automation brands, AOLISHENG validates motion the way an engineering team does — not just by factory inspection. The ALS process covers structural design from the target operating condition, prototype validation under real or simulated loads, and engineering-grade testing for load-bearing, fatigue, vibration and environment. With 30+ working-condition profiles across 11 industries and three self-owned factories, the same heavy-duty family is built to repeat in volume.

Proven in the field

An automation-equipment OEM standardized on AOLISHENG 7625 / 7120 slides for cabinet and fixture drawers, getting rigid, full-extension travel that held calibration through repeated service cycles. The same heavy-duty family is documented in a high-vibration environment in the RV locking case study.

AOLISHENG vs Rollon-class automation rails

Rollon (a Timken company) engineers telescopic rails and linear actuators for high-end automation — partial / full / over-extension in steel, stainless steel or aluminium, with digital selection tools such as myRollon. AOLISHENG’s 7625 / 2053 / 7120 / 8027 deliver 120–350 kg full-extension side-mount behaviour in steel, 304 stainless or aluminium at a mid-market cost, with vertical-integrated manufacturing and customization (bidirectional, dual-row, locking, anti-tip). For automation OEMs standardising on rigid, serviceable drawers and bays, that is the practical, volume-cost alternative.

Frequently Asked Questions

What drawer slides hold a heavy automation payload?

Use a heavy-duty full-extension slide with margin above the loaded weight — the 7625 at 220 kg (≈485 lb) per pair covers most cabinets and fixtures, and the 8027 aluminium rail reaches 350 kg (≈770 lb) for large panels.

Do these slides deflect under load?

Ball-bearing heavy-duty travel keeps deflection low through the pull; size up a family (e.g. 7120 → 7625 → 8027) when the tray is near the rating.

Can slides be stainless for automation?

Yes — 304 stainless builds of the 7625 and 2053 families suit wash-down or corrosion-sensitive cells; the 8027 uses anodized aluminium 7005.

What load headroom should I plan for?

Add the heaviest realistic payload plus 25–30% headroom; most automation drawers land in the 120–220 kg range, with 350 kg available for heavy bays.

Are locking slides available for robot motion?

Yes — the DQ7625/DW7625 (220 kg) and DL8027 (350 kg) are single-side locking builds that keep drawers secure during robot motion and transit.

How many cycles are the heavy-duty lines rated for?

The heavy-duty families are tested to 50,000+ open/close cycles, suitable for automation duty cycles; life testing is part of the ALS engineering-grade test system.
