Product overview
1285 Series Radius Belt with Rollers is presented as an industrial conveyor component for OEM, replacement and line-development work. This page keeps the series identity and available technical data together, then explains the surrounding interfaces that determine whether a replacement or new installation will fit and run correctly.
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. 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.
Structure and interface
Rakgående och radiebaserade system ställer olika geometriska krav. Rakgående moduler är ledade runt kedjehjul i färdriktningen, medan en radie- eller sidoböjande design också måste möjliggöra lateral artikulation genom en kontrollerad kurva. Ett rakt band bör aldrig tvingas genom en kurva bara för att dess bredd passar ramen.
Check the hinge line, edge geometry, underside drive features and any retention elements against the existing system. Do not identify the product from color alone.

Selection checks
Confirm straight, radius, incline, accumulation and transfer duty.
Measure pitch, assembled width, hinge/rod position and any retention features.
Confirm compatible sprocket series, tooth count, bore and shaft.
State temperature, wet/dry duty, cleaning chemistry and special material needs.
Driftsmiljön är viktig eftersom termoplastiska material reagerar olika på temperatur, fukt, kemikalier, nötning och kontinuerlig glidkontakt. Publicerade serievärden bör användas tillsammans med deras angivna materialkoder och temperaturintervall. Ett material bör inte ersättas enbart för att det har en liknande färg; färg är inte en tillräcklig metod för materialidentifiering.
Application planning
The series must be reviewed with product footprint, load, stability, speed, transfer sensitivity, accumulation and cleaning access. For curves, the side-flexing geometry and guide path become part of the selection. For straight conveyors, support and drive alignment remain equally important.
Överföringar förtjänar samma tekniska uppmärksamhet som det långa transportbandets spännvidd. Små eller instabila produkter kan behöva en kamplatta, rullbrygga, nosanordning eller kontrollerad dödplattageometri. Målet är inte bara ett litet synligt mellanrum; gränssnittet måste stödja produkten och undvika störningar mellan rörliga moduler och stationära delar.
Drive and sprocket matching
Kedjehjulen ger det positiva drivförhållandet. Kuggantal, stigningsdiameter, borrning, nav- eller delad konstruktion, axelkilning och axiell placering bör granskas tillsammans. Dålig uppriktning kan koncentrera belastningen på endast en del av rembredden, medan en felaktig fixeringsanordning kan störa termisk rörelse.
Installation and commissioning
Before installation, inspect guides, supports, shafts, sprockets and transfer parts for wear or interference. Fit the belt or chain without forcing joints. Rotate the drive slowly or jog the machine at low speed to confirm clean tooth engagement across the width, stable guide contact and a controlled return path.
After loading representative product, observe transfers, curves, accumulation zones and any incline. Repeated impact, local lifting, scraping or a change in drive noise usually deserves mechanical investigation before continued production.
Inspection and maintenance
Underhåll är mest effektivt när det är inspektionslett. Operatörer bör övervaka gångjärnsområden, stänger, styrkontakt, kedjehjulsingrepp, ovanliga ljud, lokalt slitage, produktavlagringar och eventuella förändringar i returvägen. Att byta ut en sliten komponent utan att korrigera uppriktning eller kontaminering kan bara flytta problemet till en annan plats.
Cleaning or sanitation methods should be compatible with the selected material and with rollers, elastomers, magnets or retention features on the exact series.
RFQ preparation
För OEM- och eftermonteringsprojekt separerar en bra offertförfrågan bekräftade data från öppna frågor. Bekräftade dimensioner bör listas med enheter och mätmetod. Okänt material, belastning, hastighet eller kemisk exponering bör markeras för bekräftelse snarare än uppskattning.
- Series or existing marking
- Pitch and assembled width
- Overall conveyor layout and curve direction
- Sprocket tooth count, bore and shaft
- Product load, speed, temperature and wet/dry conditions
- Quantity and sample/replacement/OEM status
Vanliga frågor
Can a replacement be selected from a photograph alone?
Photos help with identification, but pitch, width, hinge/rod geometry and the drive interface should also be measured.
Do existing sprockets need replacement?
Not always. Check series compatibility, tooth condition, bore/shaft fit and wear before reusing them.
Can material be changed independently of geometry?
Material changes can alter temperature capability, friction and wear. Use the listed options as the starting point and request confirmation for alternatives.
How should non-standard width be requested?
Send the required assembled width and the measured module increment or an existing sample. Width rules differ by series.
What speeds the quotation?
Series, pitch, width, sprocket/shaft data, application, operating conditions, quantity and drawings or clear photos.
Fit and release checks for this series
Use the available series dimensions together with the actual conveyor interfaces. The final release should identify what is confirmed and what still needs measurement.
Confirm the stated side-flex radius or radius geometry together with belt width and guide path.
Inspect inner/outer guide contact and any TAB, magnetic or retention feature against the conveyor track.
Record compatible sprocket or mounting geometry, shaft/bore information and the condition of existing mating components.
State product, load, speed, temperature, moisture, cleaning, accumulation and transfer conditions that apply to this project.
Confirmed series data to carry into the RFQ
Pitch: 31.75 mm; Minimum backflex radius: 25 mm; Minimum sideflex radii by assembly width: 450 / 550 / 650 / 780 / 930 / 1100 / 1250 mm; Maximum working load at 21°C: 22,000 N; Working temperature: 4–65 °C dry/wet; Weight: 8 kg/m². Use these values only for the exact series shown on this page; any project-specific dimension or alternative material should be confirmed before ordering.
For a replacement, add photographs of the existing top surface, underside, edge/hinge area, drive sprockets and return end. For a new machine, add the conveyor layout and the product path so support, guides and transfers can be reviewed with the selected component.
How to apply the series data on the machine
The listed values define the series, while the conveyor decides whether that series is appropriate for the project.
Machine fit
On a curved conveyor, check the actual inside guide path through the full turn and verify that the assembled width and lateral articulation match the line. The drive and return sections must transition into the curve without forcing the chain or belt sideways.
Useful confirmed values on this page include pitch 31.75 mm, minimum backflex radius 25 mm, minimum sideflex radii by assembly width 450 / 550 / 650 / 780 / 930 / 1100 / 1250 mm, maximum working load at 21°c 22,000 N, working temperature 4–65 °C dry/wet. Keep the unit and the exact parameter name with the purchasing record so the value is not separated from its meaning.
Inspection focus
Warning signs include inner-edge polishing, outer-edge lift, unstable guide contact or irregular motion through the transition between straight and curved sections.
Before reusing surrounding parts, clean and inspect the mating surfaces and drive elements. Photograph any abnormal wear before disassembly; the wear pattern can help explain why the previous component failed or became unstable.
| Kontrollera | Praktisk granskning |
|---|---|
| Existing machine | Measure the part and the surrounding conveyor independently. Do not assume a worn component still shows the original nominal dimension. |
| New machine | Confirm machine envelope, support, drive, transfer and service access before final series release. |
| Alternative option | If material or configuration may change, state which machine dimensions are fixed and which product variables are flexible. |
| Purchase record | Keep series, width, drive/mounting data, operating conditions and any accepted drawing revision together. |
Commissioning record for 1285 Series Radius Belt with Rollers
Confirm assembly, belt or chain seating, drive/mounting alignment and clearance to stationary parts. Rotate or jog slowly when the machine permits.
Use representative product and observe the most demanding zone: curve, accumulation, incline, transfer or return support as applicable.
Check for localized wear, new noise, edge contact, rod movement, product marks or debris concentration. Record the location of any abnormality.
Keep the final series, installed width, mating component data and operating condition with the maintenance record for future replacement.
Additional series data carried on this page includes Material code: XLG; Mold-part widths: 170 / 255 mm; Standard assembly width: W = 340 + 85 × N; Surface option: Integrated rollers. Do not detach these values from the exact series or configuration when preparing a purchase description. If the machine requires a different width, material, mounting or drive arrangement, flag the change for confirmation rather than treating it as an automatic option.
Request a series-level quotation
Send the series/model when known, measured dimensions, drive or mounting data, operating conditions, quantity and drawings or photographs. Open points can remain explicit until confirmed.
