How To Buy

Edge Roller Technology (ERT)

ERT (Edge Roller Technology) Pallet Conveyors deliver precise, low-friction pallet and tray handling for a wide range of applications from automated electronics assembly to heavy-duty industrial manufacturing. The open frame, belt-free design limits particulate production while maximizing accurate positioning for even the most delicate automated processes.

Features and Benefits

  • Clean, Open Roller Design
    Reduces friction, minimizes debris buildup, and prevents small parts from jamming the conveyor — ideal for cleanroom and precision assembly environments.
  • ISO Class 4 Verified for Cleanrooms
    ERT150 and ERT250 are verified for ISO Class 4 cleanrooms, supporting medical device, electronics, and pharmaceutical production.
    *To verify clean room requirements, an unloaded base conveyor was tested and did not generate particulate that would be beyond the specified standards. However, the verification does not provide assurance that any or all applications will meet this requirement. Application testing is recommended to ensure clean room standards are being met. Dorner takes no responsibility in the clean room performance of the final conveyor or application.
  • Non‑Contact Zoning & Low‑Back‑Pressure Accumulation
    Slip‑roller and zone‑control technology enable smooth traffic control without pneumatic valves, reducing wear and simplifying automation.
  • Modular, Field‑Reconfigurable Design
    The patented linear gearbox design features repositionable gears, shafts, and motors to allow for fast reconfiguration and flexible line changes.
  • Wide Load & Size Range
    ERT150 handles small/light loads up to 16 kg per pallet, ERT250 supports medium/heavy loads up to 114 kg per pallet, and ERT350 manages pallets up to 1,000 lbs for force‑intensive operations.
  • Industry‑Standard Pallet Compatibility
    Supports standard pallet sizes across all models, with ERT350 offering large formats up to 1200×1200 mm for heavy-duty industrial applications.
  • Smooth, Beltless Motion
    Roller‑driven transport eliminates belt friction, reducing particulate contamination and improving system longevity in high-precision environments.
  • Advanced Traffic Control Modules
    Lift‑and‑locate, turn‑and‑transfer, corners, pallet stops, and other modules support complex routing and automated assembly workflows.
  • Heavy‑Duty Drop‑and‑Locate Capability (ERT350)
    Unique mechanism transfers external forces up to 1,000 lbs into the frame and floor, enabling pressing, riveting, and torque‑intensive operations.
  • Universal T‑Slot Integration
    Compatible with 2200 Series, FlexMove, and industry‑standard hardware for easy mounting and system integration.
