Impregnant graphite tube
Application 1
For making mechanical seals and graphite bearings
used in food, beverage, textile, chemical and other industries of the conveyor, drying machine, textile machines, submersible pump motor bearing, these parts such as grease lubricant Inevitably cause pollution, and graphite bearing strong self lubrication, corrosion resistance, don't use into lubricating oil Line running for a long time.
