Norpak Handling Ltd. supplies an unmatched inventory of material-handling solutions, including belt conveyors. The effectiveness of one of these systems depends, to some extent, on the kind of bed that it uses. The usual choice is between a slider bed and roller bed, and picking the appropriate one plays a substantial part in optimizing material handling. These bed types serve the same purpose, but are more suitable for different scenarios.
Stable support for the belt
Both slider beds and roller beds sit under conveyor belts to help support items on conveyors, but they have varying advantages. A slider bed is a large metal sheet that acts as a stable support for the belt. The key benefit of this bed is the smooth movement, although the movement of the belt against the static slider bed creates friction. Running this kind of configuration requires more horsepower, and there are other relevant issues, like belt wear.
A slider bed offers a smooth, solid, uninterrupted base for the belt, which makes it more appropriate for items with irregular shapes. Because slider beds are more stable, they can achieve high speeds despite the shapes and sizes of the products. Customers commonly use slider beds in parcel applications.
Each roller bed is made of a series of rollers that lie under the belt and turn along with the belt’s movement – creating less friction while needing less energy and fewer drives to operate. As opposed to slider beds, roller beds are used to reduce the coefficient of friction, allowing the conveyor to move a far larger total load of items. A standard slider tread uses a friction coefficient of 30 per cent, but a roller tread’s coefficient is only five per cent.
There are even cases that work best with a mix of roller and slider beds. It is wise to consult with material-handling experts for the best solution. The Norpak team can provide a better understanding of how to pick the right components. The company’s advice is based on decades of experience with the top material-handling products on the market.
