Side-Driven Belt for Side-Drive Spiral Freezers and Coolers: Replacement and New Projects

A side-driven belt is a metal spiral conveyor belt for side-drive spiral freezers and coolers. The drive engages the belt at its side, so rod pitch, turn ratio and sprockets are checked against your drum, and the belt suits the existing system before it ships.

Replacing a side-driven belt, or supplying a new side-drive spiral? Before quoting, your rod pitch (31.75 or 34 mm), turn ratio and sprockets are checked against your drum. The belt is turned on a test drum matched to your drum diameter and run on its sprockets before it ships.

Stainless Steel or POM Mesh: Which Side-Driven Belt Does Your Spiral Need?

Both run on the same 6.0 mm rods and side links at 31.75 or 34 mm pitch. Stainless spiral mesh is the usual choice; POM mesh is used where a plastic surface is needed — in the grade your temperature allows.

Will the New Belt Engage Your Sprockets and Turn on Your Drum?

Same width is not enough. A side-driven belt is pulled by sprockets and turns around your drum, so rod pitch, turn ratio, drum diameter and sprockets are checked first — before you get a quotation.

Replacement

Replacing the belt on an existing side-drive spiral

You send
Photos of the old belt with a ruler, a sample section if possible, freezer model, drum diameter and operating temperature.
We check first
Rod pitch (31.75 or 34 mm), turn ratio against your drum diameter, side link and clip connection — measured on your old belt.
Your sprockets
Pitch, tooth profile and wear checked. If they need replacing, UHMWPE sprockets are matched and run with the new belt.
You get
Before quoting: will it engage your sprockets and turn on your drum as it is, or does anything else need to change.
New project

Supplying a new side-drive spiral

How Is a Side-Driven Belt Verified Before Shipment?

Four checks that matter to you: pitch measured, tested on your drum diameter and turn ratio, run on its sprockets, and a sample kept for your re-order. You see photos and video before it ships.

  1. Side-driven belt check: rod pitch 31.75 mm measured with a caliper
    01

    Pitch measured

    Rod pitch, rod diameter, spiral pitch, link thickness and width measured against your drawing.

  2. Side-driven belt check: drum diameter test, belt turned on a test drum
    02

    Drum and turn ratio tested

    The belt turns on a test drum matched to your drum diameter and turn ratio.

  3. Side-driven belt check: sprocket running test with the belt
    03

    Run on its sprockets

    The belt is run on sprockets to check engagement before packing.

  4. Side-driven belt check: sample section retained for the order

    Sample kept, batch verified

    A sample is retained and the batch verified, so a re-order matches this one.

Also checked: material confirmed against your order · welds cleaned without arc residue · clip connections turn freely · photos and video sent before the crate is closed.

Problems You May See on a Side-Driven Belt — and How They Are Prevented

Arc residue that scratches your equipment, uneven polishing, broken clips or a wrong pitch means a stopped spiral and downtime on your line. Each one has a check before your belt ships.

Side-driven belt: arc residue at the weldProblem

Arc residue at the weld

Sharp arc residue left where the side link is welded (circled) — it scratches the equipment and product as the belt runs.

✓ Welds cleaned with a weld-cleaning machine, never ground with a drill; each weld point checked by eye and hand.

Side-driven belt: green marks after electropolishingProblem

Green marks after electropolishing

Uneven polishing leaves green marks along the edge (left). A correct finish is even, with no marks (right).

✓ Edges and surface checked section by section in daylight; marked sections are re-polished before shipment.

Side-driven belt: clips broken in transitReference

Clips broken in transit

Belts with clip connections packed flat can break clips on the way. Correct: clips fully seated, no play (marked).

✓ Clip connections checked for fit and free movement; clip belts are rolled, not laid flat.

Problem

Wrong pitch or turn ratio

31.75 and 34 mm look alike, and the same width can have a different turn ratio — the sprockets do not engage, or the belt rides up on the drum.

✓ Pitch measured on your old belt; turn ratio checked against your drum diameter; drum and sprocket tests before shipment.

FAQ

Questions Buyers Ask Before Ordering a Side-Driven Belt

Q1What is a side-driven belt?

A spiral belt driven from its side links by sprockets, used in side-drive spiral freezers and coolers. The mesh can be stainless steel spiral wire or POM, on 6.0 mm rods at a 31.75 or 34 mm rod pitch.

Q231.75 mm or 34 mm pitch — why must it match?

The rod pitch must match your sprockets. With the wrong pitch the sprocket teeth do not engage the belt. Your existing pitch is measured first and confirmed on the drawing.

Q3What is turn ratio, and why must a new belt match it?

Turn ratio describes how tightly the belt turns around the drum relative to its width. If it does not match your system, the belt will not turn correctly on your drum. It is confirmed per project against your drum diameter and belt width.

Q4Stainless steel or POM mesh?

Stainless steel spiral mesh (SUS304 / SUS316) is the usual choice; POM mesh is used where the project calls for a plastic surface. Both run on the same stainless side links and 6.0 mm rods.

Q5Can POM mesh be used in a freezer?

Only with a POM grade suited to your operating temperature. Standard POM is not suitable for freezing; a low-temperature grade is selected and confirmed in writing for your project.

Q6Can you replace a side-driven belt without the original drawing?

Yes. Photos and basic dimensions support an initial review and indicative quotation; the formal specification is confirmed on a sample of your old belt, together with your drum diameter and sprocket details.

Q7Do I need new sprockets?

Not always. Your existing sprockets are checked first for pitch, tooth profile and wear. UHMWPE sprockets can be supplied with the belt — tooth count, bore, keyway and mounting confirmed per drawing — and are run with the belt before shipment.

Q8How is the belt checked before it ships?

Rod pitch, rod diameter, spiral pitch, link thickness and width are measured; the belt is turned on a test drum matched to your drum diameter and run on its sprockets; a sample is retained and the batch verified. Photos and video are shared before shipment.

Q9How is a side-driven belt packed?

Belts with clip connections are rolled; others are laid flat. Both are packed in strapped, labelled export crates, closed after you have seen the photos and video.

Q10How are commercial terms confirmed?

They depend on the belt and the project, and are confirmed in writing in the quotation.
