Roller Conveyors

Mix and match conveyors and stands to design a conveyor system that moves parts exactly where they need to go. These conveyors have rollers that transfer items with flat or uneven bottoms, such as boxes or shipping tubes. They’re more durable and carry heavier loads than belt and skate wheel conveyors.

These conveyors don’t run on electricity, so their rollers require momentum from gravity, a push, or a powered conveyor to move. Since they’re not wired, they’re quick to set up and easy to maintain. This makes them handy if another conveyor unexpectedly shuts down or you need to extend an existing line in a pinch.

Curved and straight conveyors have connecting hooks to attach conveyor sections together.

Aluminum conveyors are roughly half the weight of steel conveyors, so they’re easier to install.

Note: Capacities are based on an evenly distributed load. The length of the material you’re conveying should be at least three times the roller spacing.

Bench-Top Roller Conveyors

Designed to rest on a work surface, these conveyors have two sets of axle holes so you can position the conveying surface 1/8" above the frame or 3/4" below the frame (position below to use the frame as a guide rail).

Aluminum conveyors are lightweight and corrosion resistant.

Note: Capacities are based on an evenly distributed load. The length of the material you're conveying should be at least three times the roller spacing.

Legal-for-Trade Inline Conveyor Scales

Weigh boxes as they flow through your conveyor line to reduce bending and lifting. These scales integrate seamlessly into your line thanks to their conveyor rollers or ball transfers, which move boxes along after weighing. A check-weighing mode flags boxes that are outside a specified weight range. And a weight accumulation mode keeps a running weight of all boxes measured. These scales are National Type Evaluation Program (NTEP) approved for use with legal-for-trade materials sold by weight.

Mount the display in front of the scale, on a nearby wall, or use the included stand to mount it above the scale. 1" digits are easy to read from a distance. These scales are rated IP65 for protection from dust and low-pressure washdowns. They plug into a standard outlet or run on the rechargeable battery for up to 72 hours. Transmit data to your PC by connecting the scale with an RS-232 computer cord (not included).

Roller conveyor scales are for straight-path flows.

For temporary jobs, set your scale on a cart (sold separately), then roll it up to your conveyor or workbench. Two of the casters are lockable, so the cart stays in place during longer jobs or when used in a conveyor line.
