Examples of applications Conveyor chain for painting line – Oven – Conveyor chain for steel industry – Sterilizer – Conveyor chain for food industry – Continuous rotation application such as rollers – etc… Product characteristics The woven material of H-Liner® SHT is composed of a friction layer backed on a high mechanical resistance composite structure. The specific composition allow the bushing to withstand high temperature (up to 285°C) while keeping really low friction coefficient in comparison with other high temperature material (PEEK…). Conditions of use Static pressure max (MPa) Thermal expansion coefficient (/K) Standard tolerances Housing Shaft tolerances Optimal shaft roughness Member of HEF Groupe, tribology expert and leader in surface engineering, HEF Durferrit masters all technologies to develop customized bushings and friction components: - Nitrocarburising specialist, owner of QPQ®, TENIFER®, ARCOR®, SURSULF®, TUFFTRIDE®… Low friction, anti-corrosion coatings: lamellar zinc, PTFE & MoS2 coatings… PVD & CVD coatings expert: DLC (aC:H, TaC), hard coatings (CrN, TiN,…): CERTESS® Anti-seizure treatment: STANAL® 400 (for stainless steel), DELSUN® (for bronze and cupper alloys) THE H-LINER® TECHNOLOGY IS A WORLDWIDE HEF PATENT -

BUSHINGS H-LINER SHT Advantages of H-Liner® SHT - Maintenance free, self-lubricating High Temperature Low friction coefficient Weight reduction Good behavior under continuous rotation Assembly instructions H-Liner® SHT bushings are best assembled by press fitting. For further information, please contact HEF DURFERRIT prior to use. Available basic forms Different forms are available with H-Liner® SHT technology: Cylindrical, sliding plates, thrust washers… Mating shaft H-Liner® SHT bushings were developed to run without lubrication. Therefore, counter shafts should be treated against...
