  • Fluon TM PTFE Micropowders Outperform Conventional Lubricant Additives for Rubber Compounds
    Many natural rubber and synthetic elastomer products used in the automotive and consumer durable industries are compounded with lubricating additives for improved tribological performance as well as processing advantages. Products like O-rings, hoses, fan belts, strips, seals and gaskets require
  • Nonlubed leadscrews
    PTFE-based coatings reduce leadscrew wear while practically eliminating maintenance. The stainless-steel leadscrews have threads coated with Danaher Motion's TriCoat PTFE-based solid-film lubricant. They perform well without oil or grease and with little to no maintenance even in environments
  • Magnalube-G Case Study - Duke University
    for better lubricants in this field. One lubricant, an all-purpose grease reinforced in its lubricity and "staying power" by a suspension of PTFE resin powder is being used to the air conditioning and refrigeration maintenance field with promising success. At Duke University the superintendant of the Air
  • Lube-for-life journal bearings
    Composite journal bearings can operate without external lubrication, even in harsh environments that challenge most conventional types. Lube-free composite journal bearings from Polygon, Co., Walkerton, Ind., use interwoven PTFE super filaments. The material provides small pockets for contaminants
  • Plastic Nuts become a hot topic
    plastic nuts let the devices run smoothly, quietly, and stiction-free, without periodic ( external) lubrication. Nuts of acetal-based plastics blended with 15% PTFE (Teflon) lubricant work for light to medium loads and speeds, but can overheat when subjected to high duty cycles and and elevated
  • Selection Factors for Seals
    seals. The general limitation on temperature for standard synthetics is about 225 F although some are available for uses up to 600 F. PTFE can be used over a temperature range of -400 to 550 F, although most manufacturers rate PTFE seals on the basis of 500 F maximum temperature. Asbestos
  • Bearings take the heat
    to 1,000 F (or higher in nonoxidizing environments), beyond the range of liquid and solid lubricants such as PTFE and molydisulfide, and above the melt point of polymer bearings. They also work at cryogenic temperatures down to 450 F. Graphite alone lacks the durability for bearings so it is often
