2 Introduction GAR-MAX is a dual-layer, composite strength polymer fibres, embedded bearing material that combines the in epoxy resin compounded with mechanical strength of a filament- graphite, form a strong, wearwound, fiberglass-impregnated resi stant bearing surface. To meet epoxy backing and the excellent the increased demand for GARtribological properties of an anti- MAX bearings, we have expanded friction sliding layer. The high load- the production capacity of our U.. carrying capacity is the result of a plant. Please note our new part special filament winding process. numbers and modified clearances. Reinforced PTFE filaments and high- of GAR-MAX Continuous wound PTFE and highstrength fibres encapsulated in an internally lubricated, high-temperature filled epoxy resin. Continuous wound fiberglass encapsulated in a high temperature epoxy resin.!
