FR91A
This is an environmentally friendly, lead-free material. The bearing surface Lining is a mixture of polyamide-imide resin (PAI) and a special filler on a stainless steel backing with excellent corrosion resistance. It can be used for lightweight, compact bearings, and has good sliding characteristics due to PAI, the special filler, the strength of the metal material and dimensional stability.
