Durable Steel Grooved Rollers for Efficient Mining Operations

A grooved conveyor roller is a conveyor roller with one or more grooves that seat an elastic round belt (O-ring), so the roller is driven by friction from a line shaft or an adjacent roller. It is the driven roller in line shaft and roller-to-roller conveyors.

Choose by how the drive is carried. A single groove drives the roller from one belt - basic line shaft or single-belt drive. A double-O groove takes the drive in on one belt and passes it on to the next roller on the second - the roller-to-roller daisy chain that powers a whole zone from one drive. Multi-groove puts several belts on one roller for higher driven load or multiple parallel belt lines. Single and double-O are the most common.

Pressed-groove has the groove rolled into the steel tube (all-metal, any position, many diameters and R-profiles). Pulley-groove uses an injection-molded plastic pulley (dia50 / 60, R5) pressed onto the tube end - quieter, but only at the end and not separately replaceable.

Pressed-groove covers dia38, dia42, dia48, dia48.26 (1.9 inch), dia50, dia60 mm with R3 / R4 / R5 profiles (R5 most common). Pulley-groove is dia50 / dia60 with an R5 groove.

No - like a Poly-V head, the pulley is pressed on and cannot be swapped on its own (customers usually do not have the pressing equipment). Custom sizes require new injection-mold tooling.
