    For demanding logistics processes

    • High load capacity on long conveyors

      High load capacity and efficient design

      Outstanding tensile strength and efficient design

      The stable module build makes Prolink S8.1 ideal for long conveyors. Closed hinges enable exceptional tensile strength. Robust and comparatively strong modules ensure operational stability.

      As a result, the series is a go-to option for conveying parcels, containers, crates and other heavy unit goods.

    • Secure tooth engagement for stable processes

      Delivers reliable power transmission

      Delivers reliable power transmission

      Deep tooth engagement guarantees dependable power transmission. Therefore, the belt runs smoothly, even with heavy loads and on long conveyors. Robust sprocket and module shapes are geared to demanding operating conditions.

    • From reliable conveying to cross transfer

      One series. Countless conveying tasks.

      One series. Countless conveying tasks.

      Series 8/8.1 comes with open areas, in closed, non-slip or extra-grip versions for a whole range of processes. Roller-top versions facilitate low-friction cross conveying of unit goods. Pin-retained rollers enable accumulation processes with low back pressure, or targeted product separation.

    Advantages of Prolink S8.1

    • Exceptional tensile strength:Due to closed hinges and a design built for demanding conveying tasks, exceptional force transmission with small return radii (1-inch belt) is possible.
    • Quiet operation: The special 8.1 underside reduces noise.
    • Robust design: Durable modules, solid flanks and robust sprockets increase uptime and enable long conveyors.
    • Reliable power transmission: Deep tooth engagement encourages stable belt tracking and long service lives.

    • Big choice of surfaces: With open areas, closed, anti-slip, non-slip, or with extra grip.
    • Flexible material flows: Roller-top versions enable cross conveying of unit goods.
    • Accumulating and separating: Pin-retained rollers facilitate accumulation processes with little back pressure and product separation.
    • For inclines and bulk goods: Flights, side guards and hold-down tabs increase the possible applications.

  • FAQs

    What applications is the Prolink plastic modular belt series 8/8.1 suitable for?

    Prolink series 8/8.1 is designed for straight conveyors carrying medium-to-heavy products. It’s particularly ideal for long conveyors and demanding material loads. A wide range of surfaces, roller options, flights, and accessories broadens application capabilities from traditional unit goods conveying to incline, accumulation, and sorting applications.

    With heavy loads, where does Prolink series 8/8.1 excel?

    Its closed hinge design ensures outstanding tensile strength. Rigid modules facilitate smooth tracking on long conveyors. Robust modules, solid flanks and tough sprocket designs are geared to demanding operating conditions and long service lives.

    What surfaces are available for series 8/8.1?

    Due to its hard-wearing design, series 8 is built for durability in industrial non-stop operations.

    What version is suitable for applications with airflow or drainage?

    For processes like these, the S8.1-25 RAT with a 25% open area and the S8.1-30 FLT with a 30% open area are two of the options in the series. The RAT version has rounded contact points to minimize product touchpoints. The S8.1-30 FLT has an open area and smooth surface. This design strikes the right balance between product support and open area.

    Can series 8/8.1 also move products perpendicular to the conveying direction?

    Yes. The S8-0 RTP A90 features integrated rollers at a 90° angle to the conveying direction. It facilitates smooth, low-friction side-transfer and accumulation of unit goods. Therefore, this version is ideal for material flows where products are transferred or diverted sideways.

    Is series 8/8.1 suitable for accumulation and separation applications?

    Yes. Pin-retained rollers enable accumulation processes with low back pressure, or targeted product separation. The guide rail positioning defines the function concerned. This enables integration of extra process steps to the conveyor.

    What options does series 8/8.1 offer for incline conveying and bulk goods?

    A wide selection of flight heights and types is available for incline conveyors. Side guards help contain and guide bulk materials. Hold-down tabs offer enhanced tracking support in compatible conveyor layouts. Therefore, the series can adapt to more demanding conveyor shapes and diverse products.

    Does series 8/8.1 offer options for specialized safety requirements?

    Yes. A flame-retardant material is available for some versions. The series also comes with anti-slip and non-slip surfaces for walk-on applications. The application, environment and specs govern which version is right for you.
