Design Introduction
The POLYESTER LUBRICATION series bearings (PFB) in Kintowe product series are continuously wound with glass fiber and epoxy resin material (bearing layer), filled with PTFE fiber and high strength fiber internal lubricant and high temperature epoxy resin as sliding layer, so as to form a natural concentric high strength bearing without joint and overlap This high-strength laminate structure allows bearing wall thickness of only (1.59mm-3.18mm), reducing product size and bearing weight during assembly such composite bearings exhibit extremely low friction coefficients and high bearing capacity
