Next Evolution of Dorner’s Edge Roller Technology Conveyor, the ERT150


The next evolution in Dorner’s Edge Roller Technology conveyor platform, the ERT®150, is ideal for small and light-load assembly automation, as well as medical and medical-device assembly application. The ERT platform is the only pallet conveyor of its kind available with an ISO Standard Class 4 rating for cleanroom applications. Earning the ISO Standard 14644-1 Class 4 rating means Dorner’s ERT150 will conform and not contribute to the contamination of cleanrooms to those standards.

As implied by its name, the ERT150 uses rollers to move pallet conveyors smoothly with no friction (a byproduct often seen in belt-driven platforms). The conveyor’s open design eliminates concerns of small parts or screws dropping into rollers and causing conveyor damage or jamming.

The ERT150 is suited to operate in cleanroom environments requiring a pallet handling conveyor. It is capable of zoning for no or low-back pressure accumulation and is ideal for automation assembly applications within industries including:

  • Medical and medical devices
  • Electronics
  • Consumer goods

The rollers are driven by a patent-pending, energy efficient linear gearbox that gives customers added flexibility with motor positioning and zoning. This allows for zone and slip roller operation. Simply removing a lower gear creates independent zones. The non-contact zone control provides simplified traffic control that eliminates pallet stops and costly pneumatic valves. Conversely, slip rollers can be used for full length runs with conventional pneumatic pallet stops. The rollers are easily accessible and can quickly be replaced without affecting the remaining portion of the conveyor.

Technical specifications of the new ERT150 include:

  • 24 mm (0.95 in.) diameter rollers on 32 mm (1.36 in.) centers
  • 80 mm (3.15 in.) to 480 mm (18.9 in.) wide
    • Standard pallet widths from 160 mm to 320 mm wide
  • Lengths from 128 mm to 2,432 mm in 64 mm increments
    • Conveyors longer than 1,216 mm contain two gearmotors
  • Loads up to 35 pounds per pallet or tray
  • Speeds up to 37 m/min (121 feet per minute)
  • Driven rollers for indexing / zoning and transport applications
  • Slip rollers for low back pressure accumulation

What makes the ERT so different?

Belt Conveyor
  • Force to move product has tension and friction
  • Force to accumulate product doubles that friction
Roller Conveyor
  • Force to move product has almost no friction (less debris and dust)
  • Force to accumulate product with driven roller is higher, but not as high as belted
  • Slip roller technology reduced the force by almost 75%
  • Motor is 8x smaller, uses less electricity

Common Questions

  • Q: What type of applications are these designed for?
  • A: Cleanroom applications (medical product and device manufacturing/assembly/packaging) and Small and Light-Load Assembly Automation


  • Q: How do you create zones?
  • A: Simply remove connecting gear and add gearmotors to create zones within the conveyor. Multiple zones can be created within a single conveyor frame.


  • Q: Why do you want to create zones?
  • A: To provide simplified traffic control and eliminate pneumatic stops which can be costly and can create an issue in cleanrooms due to the air they release.


  • Q: Is the ERT cleanroom approved?
  • A: It is ISO Class 4 approved for cleanrooms.


  • Q: Can a system use both slip and driven rollers?
  • A: Yes. Driven and slip rollers can both be used. They are also interchangeable within one base conveyor and can be swapped out in the field.


  • Q: Where is the gearmotor located?
  • A: The gearmotor can be moved on 125 mm increments along the length of conveyor frame. The drive shaft can be moved to any roller zone.


  • Q: What are the benefits vs the competitor?
  • A: Unlike the competitor, Dorner’s ERT features a smooth open roller design that eliminates concerns of small parts and screws dropping into rollers and causing conveyor damage or jamming.
