PFC-SB is generaly used for low speed pendular movement like angular motion. As the sliding surface is spherical shaped,it can also be used for tilting motion like aligning movement in a certain angle range.Even the nonconcentricity between the supporting shaft and the shaft shell hole is bigger, it can still work very well.PFC-SB spherical bearing is processed with composite materialfiber-reinforced phenolic resin,fiber- reinforced polyester resin and so on. It has virtually no electro-chemical corrosion in seawater or other aqueous solutions,which means that the composite beaing will not nust. Kintowe' s spherical bearing has large load capacity and impact resistance,also has the properties of corrosion resistance,wear resistance,self-aligning,good lubrication or self-lubricating and no pollution,even if dislocation installation, it can work also very well
