PTFE Bearing Pads

Additional Details

Problem:Storage tanks handling chemicals at elevated temperatures must be constructed with bearing pads to allow for normal expansion and contraction. Bearing pads made of rubber, lead, cast bronze and steel are all subject to corrosion and weathering in varying degrees. Periodic inspections are necessary to avoid structural damage. Answer:Bearing pads made of PTFE are completely resistant to practically all corrosives and weathering. They evidence no loss of mechanical strength at temperatures from —450°F. to +500°F. (at a constant load factor). Self-lubricating PTFE bearing pads slide more freely thereby reducing the friction factor and eliminating maintenance.
