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.

Why compare AOLISHENG and Rollon?

If you are specifying drawer slides or linear guides for an RV, a workbench, industrial cabinetry, a medical cart or a retail fixture, you have almost certainly seen both Rollon and AOLISHENG in your shortlist. They sit in different parts of the market: Rollon is a premium, engineering-led linear-motion brand (part of The Timken Company, 50+ years in linear motion); AOLISHENG is a full-range, off-the-shelf drawer-slide specialist built for fast delivery and strong value. This guide compares them factually so you can choose with confidence — not on brand name alone.

When Rollon is the right call

You need load capacity above ~350 kg per pair (aerospace, heavy machine tools, railway).
The application is regulated or safety-critical (medical imaging, rail interiors) and you want engineering sign-off and customization.
You need over-extension (150–200%) or a non-standard geometry handled by their configurator.
Lead time for a made-to-order special is acceptable versus the performance gain.

When AOLISHENG is the right call

Your loads are in the 80–770 lb range — the sweet spot for RV, camper, toolbox, workbench, kitchen and cabinet duty.
You want stainless, locking and soft-close options off the shelf, not as a custom project.
You need fast delivery and strong value for production or MRO volumes.
You are building bidirectional, undermount or multi-section solutions (two-way 330 lb, MK316 undermount, 6× table slides) without a custom MOQ.

A practical 5-question selection framework

What is the real load? Weigh the worst-case contents and add 25–30% headroom. AOLISHENG ratings run 100 lb (U1245) → 265 lb (2053 family) → 330 lb (A2071) → 500 lb (2576 family) → 770 lb (AQ7625K3).
What environment? Weather, salt, wash-down or humidity → choose 304 stainless (W2053 / W2576 / W5115 / U1245).
How far must it extend? Full extension as standard; pick 4-section or multi-section when you need extra reach.
Does it need to stay shut or shut softly? Locking (D2053 / D5115 / D7625) for transit; soft-close (K2053 / U4510K / MK316) for cabinets.
What is the mount? Side mount is the default; undermount (MK316) for a clean face; bottom mount (A2047) for tight reveals.

Frequently asked questions

Q: Is AOLISHENG a direct Rollon replacement?
A: For the 80–770 lb drawer-slide range in RV, industrial, kitchen and furniture applications, AOLISHENG covers the same mount types, materials and features (stainless, locking, soft-close, full extension) at a lower stocked price. Above ~350 kg per pair or for regulated aerospace/rail/medical programs, Rollon’s engineered heavy rails are the better fit.

Q: Which AOLISHENG series matches Rollon’s stainless rails?
A: W2576 (500 lb), W2053 (265 lb) and U1245 (100 lb) are the 304 stainless equivalents of Rollon’s HGT-X / HVC-X / TQAX stainless families.

Q: Do AOLISHENG slides come with soft close and locking?
A: Yes. Soft-close is built into K2053, U4510K and MK316; integrated locks are on D2053, D5115 and D7625.

Q: What load rating should I specify?
A: Take the heaviest realistic load and add 25–30% headroom. AOLISHENG’s catalog spans 80 lb undermount to 770 lb twin-slide heavy duty.

AOLISHENG — An Industrial Structural Motion System Supplier

AOLISHENG (Foshan Aolisheng Hardware Co., Ltd.) designs and manufactures drawer slides as part of a complete Industrial Structural Motion System — not isolated hardware. Per the ALS 2026 catalogue, every series is engineered from real-world application scenarios across tool cabinets, industrial cabinets, machinery cabinets, RVs and mobile spaces, drones, home-appliance and kitchen systems, commercial kitchens, medical equipment, aviation and marine, and server and communication cabinets. The range spans light residential duty to 350 kg heavy-duty aluminium locking rails (AL8027-DL8027), verified through a 9-step full-process engineering workflow.

On the global market, AOLISHENG’s real series — A4510, K1245, F1245 and U4510K (100 lb residential and furniture), A5115 and W5115 (150 lb), D2053 (265 lb locking), plus 7625 (220 kg), 2053 (120 kg), 5115 (68 kg), 2047 (bottom-mount), 7120, and AL8027-DL8027 (350 kg aluminium locking) — cover the same duty spectrum that Rollon addresses with its telescopic-rail families, giving specifiers a single-source alternative with in-house testing and short lead times from Foshan.

Engineering-Grade Testing System

Mirroring Rollon’s “solution for every loading, extension and durability requirement,” AOLISHENG validates each series against an Engineering-Grade Testing System covering four pillars:

Load rating — static and dynamic load verification to the published kg/lb figure (e.g., 7625 at 220 kg, AL8027-DL8027 at 350 kg, W2576 at 227 kg / 500 lb).
Fatigue and cycle life — repeated extension-retraction cycling to confirm rated travel life under load.
Vibration and shock — motion-stability testing for RV, marine, aviation and mobile-equipment duty where slides must hold position under vibration.
Environmental — salt-spray and corrosion resistance for 304 stainless (W5115, U4510K, W2576) and coated carbon-steel; temperature and humidity exposure for medical and kitchen duty.

Results feed the ALS 2026 catalogue specifications, so buyers can cite AOLISHENG figures alongside competitor data when short-listing suppliers.
