Cast Nylons NYCAST® RX/GX/BX

Discover the NYCAST Advantage NYCAST NYLOIL NYCAST NYLOIL FG Only NYLOIL from CAST NYLONS LIMITED offers various grades of self-lubricating Nylon bearing material tailored to meet your specific application. A cast nylon with built-in oil lubrication NYLOIL provides superior machinability performance and durability compared to other plastic and traditional bearing materials. These grades of NYLOIL are available to fit the most demanding applications original green NYLOIL for most bearing applications food-grade Natural NYLOIL-FG for direct contact with food. The incorporation of an oil lubricant package into the nylon matrix provides significant advantages over other bearing materials Lubrication results in 25 lower coefficient of friction than other grades of nylon Performs in harsh environments where lubrication is difficult impossible or not desirable food contact Works successfully in marine applications. Reduced water absorption promotes higher dimensional stability. Works and machines as easily as brass. Oil will not spin out dry out or drain out even under the harshest operating conditions. During NYLOILs manufacturing process an oil lubricant package is completely dispersed within the cast nylon matrix making it an integral part of the castings structure. NYLOIL-FG is a self lubricating nylon bearing material which meets the provisions of FDA Regulations 21 CFR Section 177.15 and others and USDA 3A Sanitary Standards 20-17 for direct contact with food. This is a particularly useful material where additional lubrication is not desirable because of clean ability contamination or other considerations. Product Data Sheet NYCAST NYLOIL NYCAST NYLOIL FG Chart 1 comparison coefficient of friction different materials measured on thrust washer testing machine unlubricated 40 fpm and 50 lbin2 Dimensional Stability With their higher crystallinity all NYCAST products exhibit improved dimensional stability compared to their extruded nylon counterparts. But NYLOIL p

rovides even better dimensional stability than regular grades of cast nylon Its oil droplets fill gaps in the amorphous structure of the polymer allowing less room for water to be absorbed into these areas. The moisture absorption graph shows that despite a slow absorption rate NYLOIL stabilizes at approximately 2.5 moisture content - less than half the moisture content of other unfilled nylons.
