Manufactured from 440 Stainless Steel. Intended for applications in harsh environments that require increased corrosion resistance. Excellent choice for outdoor use or for applications such as food production facilities that require frequent wash-down and cleaning. Food grade grease is available. Our standard needle rollers are replaced with a non-metallic engineered plastic bushing which eliminates or reduces the need for bearing lubrication. These hex head bearings are intended for self-lubricated applications. Continuous feed oil lubrication can be used in order to reduce wear.
