® bearings fiberglide® fabroid ® the graphs below are typical wear curves for two types of self-lubricating liner materials standard fiberglide® a and fabroid® g the standard fiberglide® a material is suitable for most applications and significantly outperforms other bearing types but should your application include extraordinarily high static and/or dynamic loads extremes of temperature or chemical resistance requirements transport dynamics manufactures a variety of liner materials and backing for critical service applications there are two types of fiberglide® liners depending on the product configuration and three types of fabroid® a comparison of fiberglide® and fabroid ® bearings with other self-lubricating types metal-backed fiberglide® typ dynamic load psi max static load psi maximum pv value temperature range °f chemical resistance minimum coefficient of friction 2,000 to 10,000 metal-backed fabroid® 5,000 to 20,000 60,000 1 60,000 -320 +400 excellent filled ptfe 0 to 500 ptfe impregnated bronze 500 to 3,000 oil impregnated bronze 100 to 2,000 30,000 50,000 -320 +300 good .03 2,500 10,000 -400 +500 excellent .02 20,000 50,000 -320 +500 fair .03 11,000 50,000 -65 +250 poor .05 .03 .005 fiberglide ® wear inches .004 .003 .002 .001 10,000 psi loading ±45° oscillation 5-20 cpm 1 for low speed oscillating conditions static loads over 30,000 psi or dynamic loads over 20,000 psi require metal backing of high strength stainless steel or equivalent materials transport dynamics is the originator innovator and leader in self-lubricating bearing technology with over thirty years of material development and application experience the original fabroid® liner system was patented in 1958 evolution in the development of materials has created three generations of self-lubrication liner technology 0 25 50 75 100 life cycle x 1000 .006 .005 wear inches .004 .003 .002 .001 today s materials represent a significant advance in technology and their increased capabilities offer solutions in applications previously judged to be borderline or beyond material capability contact transport dynamics engineering department for a detail publication of all our liner systems request engineering bulletin #106 bearing design guide fabroid® 20,000 psi loading ±25° oscillation 5-20 cpm 0 25 50 75 100 life cycle x 1000 7
