Rulon Bearings

(Viewing data as-entered. Click here to return)
Saint-Gobain Rulon® DC7035 Bearing/Seal PTFE
Categories: Polymer; Thermoplastic

Material Notes: Offers electrical conductivity in a low wear, self lubricating bearing material. This material is ideal in applications where static dissipation is needed. DC7035 is often used as a static bleed mechanism in bearing applications for electronic components such as disc drives, printers and scanners. Also can be used in conveyor bearings where static buildup in the belts can generate high static charges. Rulon DC7035 is an excellent bearing device to carry the static away from the conveyor table.

Information provided by distributor TriStar Plastics Corp.
