iglidur materials for use in knife-edge conveyors

Knife-edge conveyors are becoming increasingly popular, giving a compact and precise end to a conveyor. They are commonly used in food production machines, bottling lines and packaging systems, as well as point of sale units in supermarkets.

Often the rollers at the end of these knife-edge conveyors are machined from stock bar and fitted with needle rollers. A low cost and high performance alternative, however, is to use iglidur materials from igus UK. Depending on the volume, these parts can be machined from iglidur plastic stock bar or moulded from igus plastic bearing materials. Typically the rollers have a small diameter, around 3 to 6mm, are 50 to 100mm long, running at a pressure of 0.5 to 1MPa and speed of between 0.3 and 0.4m/s. Tests in the igus laboratory have shown that iglidur J, P210 and A180 are particularly well suited to this application - iglidur A180 has the added advantage of being an FDA approved material.
