Abstract : Experiments were conducted to determine friction in slide guides, operating at feeding rates. A comparative evaluation was made of the antifriction properties of numerous materials used at the present time for strap guides, and also of perspective materials, and values were derived of friction coefficients in dependence upon the duration of the stationary contact and sliding speed. Materials tested during friction along the cast iron included: metals (cast iron SCH 2.-40, bronze Br. OTSS 6-6-3, babbit B16, zinc alloys TSAM 30-4 and TSAM 10-5); plastics (metallurgical Textolite B, polyamide resin 68 of Nylon type, textolite PT, cordovoloknite 1-G, vinyl plastics, fluoro plastic-4) and graphite coated materials (ferro-graphite, anticorrosion heat conductive ATM material, bronze-graphite, graphite coated material type D, lead saturated.
