This paper aimed at the problem of uneven heating of ultra-high molecular weight polyethylene (UHMWPE) bearing in the process of UHMWPE was made into water-lubricated bearing, and have used ICEPAK software to study the temperature distribution of the UHMWPE during hot pressing. Research indicated that hot pressing UHMWPE was an unsteady heat transfer in the process of heating and holding. Air convection had little effect on the overall process. During processing, the slow heating method to process smaller UHMWPE water-lubricated bearing could effectively reduce the temperature difference. It made the inner heating of UHMWPE uniform and equated to the temperature of the shaft sleeve. This research can provide data support for temperature control and process optimization for the UHMWPE-based water-lubricated bearing hot pressing process.
