Pillow Blocks with GRAPHALLOY ® Bushings

Reduce downtime and provide maintenance-free operation For high temperature, washdown, and other tough applications

Self-lubricating GRAPHALLOY pillow blocks can reduce maintenance and frequent replacements for increased reliability and years of trouble-free operation in high temperature applications, dampers, conveyors and other difficult to lubricate sites.  These pillow blocks provide install and forget service in harsh environments and for temperatures ranging from -450º F to more than 1000º F (-240º C to more than 535º C). GRAPHALLOY bushings allow for linear expansion of the shaft through the pillow blocks.
