SF011,SF016 Bronze Self-lubricating bearing
It is made of high density special copper alloy with sintering porous bronze in its interlayer and the compound of PTFE on PB on its surface.It can offer the good properties of self-lubricating,anti-abrasion,low friction,fully developing the advantages of metal and multi-element polvmer.This product is applied to metallurgical industry,continuous casting and rolling mill,concrete machinery and spiral conveyers,etc.
Note:SF016 without lead
Cylindrical bushes,flanged bushes,thrust wahsers,strip and non-standard parts as the clients supplied drawing and etc.
Recommended housing bore tolerance is H7,while the shaft diameter tolerance is F7 or H8.
