Gravity Roller Conveyor from Robotunits

Roller Conveyor without Drive from RobotunitsThe Robotunits Gravity Roller Conveyor is used as a “stand-alone” solution, including a stand or in combination with our Powered Roller Conveyor technology.

It can be combined in the entire Robotunits Modular Automation System and is ideal for horizontal and angled transport tasks. For example, our flexible side guides, a tunnel, or necessary sensors can be attached at any time.

The low-maintenance and noise-reducing steel rollers ensure a pleasant working environment. With a load capacity of 100 kg, the robust Gravity Roller Conveyor is suitable for almost any application.

Gravity Roller Conveyor Q & A

+ What is a roller conveyor without a drive, and when should I choose it?
A roller conveyor without a drive (also known as a gravity or free-rolling roller conveyor) is a conveyor section where the rollers are freely rotating and not powered by a motor. For Robotunits’ modular system, selecting a non-driven roller conveyor means you’re choosing a solution for transporting goods passively (via gravity, push/pull, or external drive) rather than active motorized zones. Use this when you have simple transport from A to B, when incline/decline gravity flow is acceptable, or when your system already has upstream/downstream drive modules. It’s an ideal cost-efficient, low-maintenance option for container/box flows in plant logistics, especially when full powered accumulation or zone control is not required.
 
+ What specifications and design considerations should I check for a non-driven roller conveyor?
When purchasing a roller conveyor without drive, key specs to evaluate include: roller diameter and material (e.g., galvanized steel), roller spacing (pitch), frame width and overall length, load capacity per roller and per meter, incline/decline angle (if gravity flow), side guides and frame height, mounting and stand options, and compatibility with the modular automation system (such as T-slot extrusions from Robotunits). Even though there’s no drive, you still need to ensure the conveyor matches product size (box/containers), weight, throughput, and integration into your existing line. For example, Robotunits offers standard widths up to ~1200mm and lengths up to 12m for their conveyor systems.
+ How easy is it to integrate a non-driven roller conveyor into my existing line in the U.S./North America via Valin?
Integration is quite straightforward. Robotunits modular conveyors – including the roller conveyor without drive – use a standardized extrusion system, T-slot frame, and compatible accessories (side guides, stands) so they plug into your line without major redesign. When working with the U.S. distributor Valin Corporation, you benefit from local support for quoting, CAD downloads, and compatibility with U.S. standards. Although the non-driven version doesn’t include motor control electronics, you still want to check how it interfaces with upstream/downstream drives, conveyor frames, and automation zones. Integration into a North American facility is supported via Valin’s regional presence.
 
+ What are the maintenance, safety, and operational benefits of a non-driven roller conveyor?
Because there’s no drive motor and fewer moving/active components, non-driven roller conveyors are inherently low-maintenance compared to powered systems. You don’t have to worry about drive belts, motors, electrical control units, or zone logic. Safety can also be simpler: with fewer electrical parts, you reduce the risk of motor faults or control failures. You still need to check for side guide wear, roller bearings, mounting integrity, and safeguarding. Using a certified system like Robotunits ensures compatibility with clean-room standards (some dimensions are EN ISO 14644 certified) and modular replacement of spare modules/rollers reduces downtime.  
 
 
+ How do I order and configure a roller conveyor without a drive through Valin for the North American market (lead times, customization, support)?
To purchase the Robotunits non-driven roller conveyor via Valin, start by specifying your required width, length, roller pitch, load capacity, and any special features (incline angle, side guides, stand height). Provide Valin’s automation team with your plant layout and product sizes so they can recommend the correct module lengths and accessory packages. Because the version is simpler (no drive motor), lead times are typically shorter. Once quoted, you receive CAD drawings, shipping to North America (U.S./Canada), and on-site support options via Valin.
