Gravity Conveyor Sections and Replacement Rollers

Which gravity conveyor speeds up your line in 2026?

Short answer: For staging and loading, the 18 in x 5 ft roller table with stand is the strongest single buy; folding models like the Threlaco 15 in x 78 in pack away between truck days, and replacement rollers keep any frame running.

Conveyors (2026)

Gravity roller conveyors turn carrying into rolling - packing benches, staging lanes, and truck loading all move faster when boxes glide. The lineup covers steel roller tables and light-duty frames, folding portable units, a 4-meter heavy track, and the 1.5 and 2 inch replacement rollers that fit standard frames.

Four of these ten are spare parts, not conveyors

Short answer: check whether you are buying a conveyor or a bag of rollers, because the price list makes them look like the same decision.

Six of the ten here are conveyor sections and tables — things you set down and put boxes on. The other four are replacement roller and bracket packs: individual rollers, sold two, four or ten at a time, for fitting into a frame you already own.

The split is perfectly clean on price. Every component pack sits under seventy dollars and every actual conveyor sits over a hundred and nineteen. So anyone sorting this collection low-to-high sees a roller 2-pack at the top and it is not a budget conveyor — it is two rollers.

Neither is the wrong purchase; they answer different questions:

• Buy a section or table if you need a working length of conveyor now — staging, packing, loading a van.
• Buy roller packs if you are repairing a frame, replacing seized rollers, or tightening roller centers on a run you already have.

If you are replacing rollers, the measurements that must match are roller diameter, roller face length, and the axle or bracket pattern — not the conveyor's overall width. Measure an existing roller before ordering rather than the frame.

Which one should you buy?

• Buy the 18 in roller table as the fixed staging and packing lane.
• Buy the Threlaco folding unit for truck-day duty that stores flat after.
• Buy the 4 m heavy track to span dock to trailer nose in one run.
• Buy the 12 in light-duty frame for cartons and totes on a budget.
• Buy replacement rollers before a seized roller becomes the whole line's speed.

How to choose

Gravity means slope discipline

A few degrees moves cartons; more than that launches them. Set fall per foot low, test with your heaviest carton, and guard the discharge end with a stop.

Roller pitch vs carton size

Three rollers under the smallest carton at all times - that is the spacing rule. The 1.5 in rollers on light frames suit totes and cartons; 1.9-2 in steel takes heavier boxes.

Fixed vs folding

Fixed tables anchor a permanent pack station; folding frames earn their price the day the trailer leaves and the aisle comes back.

Hands off moving loads

Pinch points live between carton and roller - push from behind the carton, never brake one from the side, and keep loose cuffs off the line.

Regulatory context

Most of what people quote about conveyor safety is about POWERED conveyors, and nothing here is powered. That is worth separating out rather than borrowing rules that do not attach.

OSHA 29 CFR 1926.555 is the conveyor rule, and it is built around motors: emergency stop devices that cannot be reset from the stop station, an audible warning before start-up, and guarding where a conveyor passes over a work area. A gravity conveyor has no motor, so there is no start-up to warn about and nothing to stop — and lockout/tagout under 29 CFR 1910.147 does not attach to equipment with no hazardous energy source to isolate.

What does still apply is the mechanical hazard, and it is the one people underrate. Roller conveyors have nip points — the closing gap between a moving roller and the load, between adjacent rollers, and at the roller-to-frame edge — plus pinch points wherever two sections meet. Those are what catch fingers, loose glove cuffs and sleeves, and they are covered by general machine guarding under 29 CFR 1910.212. ⚠ If your line does have anything powered on it — a shrink wrapper, a strapping machine, a powered section further down — that equipment does need energy isolation before anyone reaches into it, and what is lockout/tagout plus how to perform lockout/tagout cover that. For the people side of a packing line, ergonomic equipment and warehouse work boots matter more than the conveyor does. NIOSH publishes the machine-safety research behind it.

Three habits cover nearly all of it on an unpowered line: never push a load with your hand on the rollers, never reach across a moving carton to catch something, and never clear a jam from underneath while a load is still on the slope. On a gravity run the energy is in the load and the grade, not in a motor — which means the only thing that stops a moving carton is whatever it hits.

Unpowered gravity conveyors sit under OSHA's general materials-handling and walking-working-surface rules rather than the powered-conveyor standards - the practical duties are guarded ends, controlled slopes, clear aisles alongside, and loads within the frame rating. Every capacity and dimension in the table is the manufacturer's published figure.

Frequently asked questions

What is a gravity conveyor?

An unpowered roller track - loads move by push or slope, no motor. It is the cheapest meters-per-dollar flow equipment a small operation can buy.

How much slope does a gravity conveyor need?

Start near half an inch of fall per foot for medium cartons and tune from there - heavier loads need less, light boxes need a touch more. Test before you commit the line.

How much weight can these hold?

Frame and roller ratings vary by model - the listings publish per-roller or per-frame figures and our table quotes them. Distribute loads; a conveyor is not a shelf.

Can I connect multiple sections?

Yes - matching-width frames butt or hook together; the collocatable light-duty unit is built for exactly that. Keep joints flush so cartons do not catch.

What size replacement rollers do I need?

Measure roller diameter (1.5 and 2 in are the standards here), between-frame width, and axle type - spring-loaded axles drop into standard frames. The roller packs in this lineup cover both diameters.

Gravity or powered conveyor?

Powered belongs to fixed production lines with controls and guarding engineering. For staging, packing, and loading, gravity does the job at one-twentieth the cost - which is why this collection is gravity-only.

Can a conveyor go through a truck door?

That is the classic use - a folding or 4 m section from dock floor to trailer nose, fed by a pallet jack or cart at the back.

Do conveyor lines need guards?

End stops at discharge, clear standing zones alongside, and no reaching across moving cartons - the hazards are pinch points and runaway boxes, both controlled by setup.

Are the cheap items here actually conveyors?

No. Four of the ten are replacement roller and bracket packs — two, four or ten rollers at a time — for fitting into a frame you already own. Every one of them is under seventy dollars, and every actual conveyor section or table is over a hundred and nineteen. Sorting by price puts the spare parts at the top.

Do gravity conveyors need an emergency stop?

There is nothing to stop. OSHA 29 CFR 1926.555 requires emergency stops and start-up warnings on powered conveyors; a gravity conveyor has no motor, and lockout under 1910.147 does not attach to equipment with no energy source to isolate. The hazards that do remain are mechanical — nip points between rollers and at section transfers — and they fall under general machine guarding.

What is a nip point on a roller conveyor?

The closing gap where a moving roller meets something else — the load, an adjacent roller, or the frame edge. It is what catches fingers, loose glove cuffs and sleeves. Keep hands off the rollers when pushing a load, do not reach across a moving carton, and do not clear a jam from underneath while a load is still on the slope.

Are any of these powered or expandable?

No. All ten are unpowered gravity equipment. There is no powered or motorized conveyor here, and no expandable or flexible scissor-frame conveyor either — those are separate product types.

How do I clean and maintain rollers?

Keep grit off the line, spin-check rollers monthly, and swap any that drag - one seized roller slows every carton and wears its neighbors. Replacements here cost less than the labor of working around them.

What pairs with a conveyor lane?

Stretch wrap at the end of the line, rated shelving beside it, and tie-downs for what rolls into the truck.

Our methodology: what is on this page, and what it cannot do

We counted this collection against the storefront and read all ten product titles before describing it, and the count changed how the page opens: four of the ten are component packs rather than conveyors, and the price list does not make that obvious. We judge attributes from titles and listing data only, never from the shared descriptive copy that repeats across product pages. Capacities, dimensions and roller specifications are the manufacturers' published figures quoted as listed — we do not load-test conveyors, and where a listing does not publish a capacity we leave it blank rather than inferring one from the frame. We also separate the regulations that apply from the ones that get quoted: the conveyor rule at 1926.555 governs powered equipment, nothing here is powered, and we say so rather than borrowing authority that does not attach. What we do not do is tell you what slope to set or how much to load a given section, because both depend on your carton, your floor and your run length — the manufacturer's figure for the section you buy is the number to work to.
