Small Radius Spiral Freezer Belt

A spiral freezer belt built for a 1.1 turn ratio, a small-radius geometry that supports compact spiral systems. Because the inner and outer pitch combination decides how the belt turns, we confirm it on your drawing before production.

Your concerns, and how we handle them

“A tight turn makes the belt bind or ride up.”

Inner and outer pitch are confirmed on your drawing, and pitch is measured during production and at final inspection.

“The pitch is not what the drawing says.”

Pitch is checked with calipers against the drawing — 19.05, 27.4 and 38.1 mm — and recorded.

“Sprockets don't match the belt.”

Stainless or polymer sprockets are matched to the confirmed pitch; bore, keyway and teeth are confirmed on drawing.

“The next order won't match.”

Repeat orders are built from the same approved drawing and order records.

Options

  • Pitch combination: 19.05 × 27.4 mm or 27.4 × 38.1 mm
  • Edges: button welded (compact retained rod end), flat-hat welded (low-profile finished end), rod welded (direct welded retention)
  • Surface: pickling or electrolytic polishing
  • Sprockets: stainless steel SUS304 / SUS316, or polymer (nylon, UHMWPE, POM); bore, keyway and teeth confirmed on drawing

What questions do you have for us?

What is a small radius spiral freezer belt?

It is a spiral freezer belt built for a turn ratio of 1.1, so it turns on a tighter radius than standard spiral belts (1.15–2.5). It suits compact spiral systems where floor space is limited.

Which pitch combinations do you produce?

We produce two inner × outer pitch combinations: 19.05 × 27.4 mm and 27.4 × 38.1 mm, with 5 mm rods.

What belt widths are available?

Small radius belts are made from 300 to 1200 mm wide, or to your drawing. Reference builds include 660 mm and 1067 mm widths.

Which edge and surface options are available?

Button welded, flat-hat welded and rod welded edges, with pickling or electrolytic polishing.

Do you supply matching sprockets?

Yes. Stainless steel sprockets in SUS304 or SUS316, or polymer sprockets in nylon, UHMWPE or POM. Bore, keyway and teeth are confirmed on drawing.

How do you check the pitch before shipment?

Pitch is measured with calipers during production and again at 100% final inspection, against your approved drawing. Third-party inspection is supported on request.

Let us show you how we check every belt

  1. Material in. Every incoming batch arrives with steel mill documentation and is checked by spectral and hardness testing.
  2. Wire and rod drawn in-house. Because we draw our own stainless wire and round bar, wire size is controlled from the start.
  3. Drawing review. Our engineers check structure, pitch, edge, welding and drive relationship before quoting.
  4. Trial and first article. A complete first article is made and confirmed before mass production.
  5. In-process inspection. Pitch and dimensions are checked and recorded during production.
  6. 100% final inspection. Every formal belt is inspected before packing. Our job isn’t done until your belt passes final inspection against your drawing.
Don’t take our word for it — inspect it. Third-party inspection and factory audits are supported on request, and customer factory visits are welcome.
