Benefits of Edge Roller Technology (ERT) 250 Conveyor

Our precision edge roller pallet and tray handling conveyors provide efficient, non-contact zoning for medium & heavy load assembly automation applications. They feature a clean, open roller design and are ISO Class 4 approved for cleanrooms.

Best for:

  • Pallet & tray handling
  • No & low back pressure accumulation
  • Cleanroom applications
  • Large & medium assembly automation
  • Medical Product Manufacturing
  • Packaging
  • Medical Device Manufacturing
  • Automotive Assembly
  • Electronic & Consumer Goods Assembly
  • Appliance Manufacturing

Sizes & Measurements

  • 120 mm to 960 mm wide
  • 150 mm long tray minimum
  • 38 mm diameter rollers on 50 mm centers

Loads & Speeds

  • Loads: up to 114 kg (250 lbs) per pallet or tray
  • Up to 6.8 kg (15 lbs) per roller
  • Speeds: up to 37 m/min (121 ft/min)


  • 320 to 800 mm pallets
  • Static conductive HPDE skirt
  • Proximity sensor pick-up on side and bottom
  • Optional pin tracking ball bearings for corner conveyors

Zone & Slip Roller Technology

  • Non-contact zone control eliminates pallet stops and costly pneumatic valves
  • Low back pressure slip rollers can be used for full length with conventional pneumatic pallet stops
  • Individual rollers can be replaced without affecting the remaining portion of the conveyor

Easily Reconfigurable

  • Gears, drive shaft, and gearmotor can be repositioned in the field
  • Lower gears can be removed and gearmotor added to create new zones
  • The drive shaft can be moved to any roller zone and relocated to the lower height for added product clearance

Patent Pending Gearbox Drive Design

  • Durable, linear gearbox design provides a robust and flexible method of driven rollers
  • Reversible motors for assembly automation
  • 50 watt, 3.5 amp, low voltage brushless DC motors save space and provide improved efficiency
  • All motor controllers are Ethernet IP, Modbus TCP or PROFINET for easy of control logic, wiring and communication
