What this product family is designed to solve
Comb plates, return rollers, guide elements, transition parts and other interfaces around the belt or chain. This page is organized for industrial buyers who need to narrow a product family before series-level quotation.
A plastic modular conveyor is a positive-drive system. The belt or chain should be selected as part of a complete mechanical interface that includes the conveyed product, support surface, shaft arrangement, sprocket position, return path, guides, transfers, temperature, cleaning regime, and accumulation behavior. A small geometric mismatch can alter articulation or tooth engagement, so purchasing decisions should be based on measured interfaces rather than visual similarity alone.
Configuration paths
- Confirm the series-specific geometry and mating interfaces.
- Record dimensions and operating conditions with units.
- Keep unverified assumptions out of the released configuration.
Separate straight, radius/side-flexing, incline, accumulation and transfer duty before choosing a series.
Choose closed, open, ribbed, roller or grip surfaces according to product footprint, drainage, transfer and traction needs.
Use series and pitch to select compatible drive/idler components; verify bore and shaft data.
Record temperature, moisture, cleaning chemistry, abrasion and special material requirements.
Selection variables
For replacement work, the most useful starting information is the existing belt or chain identification, pitch, assembled width, hinge or rod arrangement, edge profile, sprocket tooth count, sprocket bore, shaft size, and clear photographs of the drive and return ends. When a legacy marking is unreadable, a dimensioned sketch and several perpendicular photographs are more reliable than one perspective image.
Operating environment matters because thermoplastic materials respond differently to temperature, moisture, chemicals, abrasion, and continuous sliding contact. Published series values should be used together with their stated material codes and temperature ranges. A material should not be substituted solely because it has a similar color; color is not a sufficient material identification method.

View specificationsApplications and operating conditions
Food and beverage processing, bottling, packaging, cooling or freezing and general material handling create different combinations of product support, cleaning, accumulation, curve and transfer requirements. A useful application description includes product dimensions and base, line speed, conveyor width, incline or curve geometry and whether the conveyor accumulates product.
Transfers deserve the same engineering attention as the long conveyor span. Small or unstable products may need a comb plate, roller bridge, nose arrangement, or controlled dead-plate geometry. The objective is not merely a small visible gap; the interface must support the product and avoid interference between moving modules and stationary parts.

Compatibility checks

| Check | What to confirm |
|---|---|
| Belt/chain series | Confirm exact family and pitch before ordering sprockets. |
| Sprocket | Verify tooth count, bore, shaft and drive/idler function. |
| Support | Check wear strips, return rollers, guides and transfer hardware. |
| Width | Use the series-specific module increment or assembly rule. |
| Curve duty | Use only a side-flexing/radius design where a curve is required. |
| Material | Match stated material options to temperature and environment. |
Record the configuration before quotation
For Plastic Conveyor Components, the useful purchasing record is the exact series or measurable replacement geometry, assembled width, surface or attachment configuration, and the mating drive information. Keep the belt or chain description together with sprocket family, tooth count, bore or shaft details, guide or return components, and any transfer part that physically depends on the selected geometry. This prevents a later quotation or reorder from being based on the product name alone.
Add the operating duty to the same record: conveyed product, load, speed, temperature, wet or dry service, cleaning method, accumulation, incline or curve condition, and quantity. If a value is not known, mark it as an open confirmation item rather than estimating it. For a replacement, photographs of both the moving component and the surrounding conveyor are especially useful because wear on sprockets, guides or support parts can affect the decision even when the replacement belt or chain is correctly identified.
Frequently asked questions
How do I choose between a modular belt and a tabletop chain?
Start with product footprint and conveyor width, then compare transfer, curve, accumulation and cleaning requirements.
Can a straight-running belt be used on a curved conveyor?
No. A curve requires a belt or chain designed to articulate laterally within its stated radius and guide arrangement.
Should existing sprockets be reused?
Only after series compatibility, tooth condition, bore/shaft fit and wear are checked.
Can an obsolete part be matched?
Yes, when pitch, width, drive details and sufficient photos or a sample are supplied.
What belongs in the RFQ?
Series or existing marking, pitch, width, layout, product load, environment, sprocket/shaft data, quantity and drawings/photos.
Fit checks before selecting a series
The product family narrows the search, but final selection still depends on the surrounding conveyor. Use the checks below to prevent a visually similar component from being treated as mechanically interchangeable.
Record mounting dimensions, fastener locations, shaft or guide size and the moving part that the component supports.
State whether the component is used at the carryway, return path, guide, transfer or drive end.
Record product load, speed, temperature, wet or dry service, cleaning chemistry and contamination that can affect material or wear.
Provide series markings when available, direct measurements, sprocket/shaft information, quantity and photographs of the drive and return ends.
Replacement projects: compare the old component and the mating conveyor together. A new belt or chain can still perform poorly if the existing drive, guide or support components are worn or misaligned.
New equipment: release the belt or chain only after the drive, support, transfer and cleaning-access details are defined. This makes the product choice part of the machine design rather than an isolated component decision.
Prepare a series-level RFQ
Send the existing series or product marking when available, pitch, assembled width, drive and shaft data, application conditions, quantity, and clear photographs or drawings. Unknown values can be marked for confirmation.
