This product category consists of support rollers with bearing bases made of plastic (polypropylene), which are pressed into the roller body (support roller tube).
Depending on the type series, different designs are possible for the integration of the bearing shelves in the reel body. The roller body can be fixed using a leading edge, a ball bearing bushing, a nut or a circlip.
On request, the rollers can be made conductive in order to avoid electrostatic charges.
