Radius Side Flexing Plastic Modular Belts
Use this family as a selection direction, then confirm the actual pitch, face, width and conveyor interface.
A horizontal curve is not just a straight conveyor bent around a corner. The belt must articulate laterally while remaining guided and supported. Inside radius, belt width, curve angle, guide geometry and drive position therefore belong in one selection package.


Begin with the conveyor plan view. Mark the inside radius, total turn angle, straight sections before and after the curve, drive location and belt width. Then add the product footprint and whether products accumulate through the turn. This drawing is usually more useful than a request that only states “25.4 mm radius belt”.
For Radius Modular Belts for Curved Conveyors, the conveyor should be described as a specific process position rather than only by a belt name. That gives a new-design or replacement RFQ enough context to distinguish support, opening, path and drive needs.
| Input | What to describe |
|---|---|
| Inside radius | Measured to the relevant belt/guide reference |
| Larghezza della cintura | Critical to the curve relationship |
| Curve angle | Total direction change |
| Drive location | Before/after curve or other system position |
| Guide system | Track/profile and wear interface |
| Product | Footprint, stability and accumulation through the curve |
The wrong radius family can bind in the curve, overload guides, track poorly or create unstable product motion. A correct nominal pitch does not prevent those failures if the lateral geometry is wrong.
For Radius Modular Belts for Curved Conveyors, solve product support, process opening, conveyor path and drive compatibility first. Material and project documentation can then be confirmed for the selected configuration.

Use a radius family from the start for horizontal curves. Radius reference configurations include 25 mm pitch with 52% open area and 25.4 mm pitch with 47% and 55% open-area examples. Those references show available family directions but do not define every permissible radius/width relationship.
Pitch narrows the belt family and sprocket system, but lateral articulation and guide geometry determine curve behaviour. Never use pitch as the sole cross-reference for a radius belt.
Open area can support cooling, drainage or process airflow through a curve, but product support remains important because centrifugal and guide forces can change how the product sits on the belt.
A reliable RFQ includes the actual inside radius, not “standard curve”. If the existing line is difficult to measure, send a plan-view sketch with belt width, curve angle and several reference dimensions.
| Curve input | Perché è importante |
|---|---|
| Larghezza della cintura | Radius capability is related to the selected family and width |
| Inside radius | Defines the turn requirement |
| Curve angle | Sets total path through the guide system |
| Guide profile | Controls location and wear through the curve |
| Drive position | Changes how the belt enters/leaves the curve |
| Ingombro del prodotto | Checks stability and support through the turn |

On a radius modular belts for curved conveyors conveyor, sprockets, pins, support strips and guide profiles belong in the review whenever they affect the process or refurbishment scope. Pitch is only one drive input; underside geometry and tooth engagement still have to match. Measure wear-strip and guide sections wherever they locate the belt or product.
Inspect inner and outer guide wear, belt edge condition, hinge articulation and sprocket engagement. Uneven wear can indicate alignment, guide or radius problems rather than normal belt consumption.
For a new radius modular belts for curved conveyors installation, verify belt direction or orientation where applicable, sprocket position and engagement, guide clearance, return support and transfer alignment. For replacement work in this duty, compare the old wear pattern with the surrounding conveyor before assuming the belt itself caused the problem.
| Zona | Inviare |
|---|---|
| Applicazione | Process step and conveyed product |
| Belt geometry | Pitch if known, width, face/open area and overall length/centre distance |
| Conveyor path | Straight/curve, inside radius and transfer points |
| Guidare | Sprocket photos/drawing, tooth count, shaft/bore and spacing |
| Dovere | Load, speed, wet/dry condition, cleaning and relevant environment |
| Commerciale | Quantity, destination, project stage and requested documentation |
No assumption should be made. Side-flexing geometry is part of the product.
It is configuration-dependent. Send belt width and the required inside radius for confirmation.
Open-area radius families can support airflow, but product support, curve geometry and process conditions must all be reviewed.
Send the information already available for the radius modular belts for curved conveyors section. A drawing is useful, but a clear photo set plus a few measured dimensions can also start the configuration review.
