O-Belt Roller Bearings
End caps grooved for a round O-belt, the simplest way to slave one roller to the next. A single elastic belt drops into the grooves, takes up its own tension and can be changed in seconds by hand.

The problem this group solves
On light lines, drive maintenance has to be something a line operator can do without tools. An O-belt group is exactly that — no tensioner, no chain breaker, no alignment.
How to choose
Choose groove diameter and belt cross-section together, and keep the roller pitch within the belt's stretch range so it tensions itself.
Typical applications
- Light carton and tray driven zones
- Short slaved groups behind a motor roller
- Lines needing tool-free belt changes
- Low-noise drive on light-duty conveyors
Where O Belt Roller Bearings is specified
Zero-Pressure Accumulation Zones
Zoned accumulation built on brushless motor rollers with slaved idlers, so cartons queue without touching.
Comparison GuideChain Poly-V or O-Belt Drive Between Rollers
Once one roller in a zone is powered, the rest are slaved to it. Three drive profiles do that job, and they fail in different environments.

Frequently Asked Questions
How much can an O-belt drive?
Less than poly-V or chain — it is a light-duty drive. For heavier cartons move up to a poly-V or sprocket cap.
Do O-belts need a tensioner?
No. The elastic belt provides its own tension, which is why the roller pitch matters when ordering.
