How long is it taking to reach the 150? We use the 020 here along with 023 and have very good results with our machine. The 023 is rated for a higher temp then the 020 but I don't know about staying power. We heat from both the bottom and the top

Most ovens I know use oil to lubricate conveyor chain, not grease. Anyway, is this what you're using: NMG No Melt Grease NLGI 2 (operates from -20�C to +270�C) NMG is a long-fibred highly adhesive grease which does not melt or drip at high temperat
