Round Pins & Connecting Rods for Modular Belts
Connecting pins and rods used to assemble modular belt hinges and support maintenance/replacement.
Component overview
Connecting pins and rods used to assemble modular belt hinges and support maintenance/replacement.
Treat Round Pins & Connecting Rods for Modular Belts as part of the conveyor interface. A reliable quotation starts with the belt or chain identity plus the dimensions and mounting details that this component has to match.
Dimensional and material range
The component range includes round pins from approximately Ø2 to Ø10 mm, with examples at Ø4.5, Ø4.9, Ø6.2 and Ø7.9 mm. Material examples include PP, PE, PA and POM. These values show the available direction; the correct pin still depends on the exact hinge bore, retention method and belt construction.
Selection table
| Parameter | Reference |
|---|---|
| Diameter range | Approximately Ø2-Ø10 mm reference range |
| Example diameters | Ø4.5 / Ø4.9 / Ø6.2 / Ø7.9 mm |
| Material examples | PP / PE / PA / POM |
| Length | Project-specific |
| Retention / end form | Confirm from belt geometry or sample |
| Colour | Not a mechanical identifier |
Pin fit is a hinge-system question
A connecting pin passes through repeating hinge geometry, so the usable diameter is governed by the actual hinge bore and the retention method. A loose pin can increase movement and wear; an oversized pin can prevent assembly or damage the hinge. Record whether the pin is retained by an end feature, cap or belt-edge geometry.
For maintenance spares, send one intact pin if possible and state the belt width. The required pin length is linked to the assembled belt, not just the nominal pin diameter.
Replacement and inspection checks
| Check | What to record |
|---|---|
| Pin diameter | Measure a healthy sample where possible |
| Length | Record overall and retained length |
| End / retention form | Photograph both ends |
| Hinge condition | Check worn hinge bores before duplicating an old pin size |
Frequently asked questions
Can I order only by diameter?
Diameter is important, but length and retention/end geometry also need to match the hinge.
Can the material be inferred from colour?
No. State the required environment/material documentation or provide an existing specification.
Request the matched component set
For Round Pins & Connecting Rods for Modular Belts, send your belt or chain identification, dimensions, quantity and conveyor interface. A photo or drawing is especially useful when the existing component is being replaced.
