INDRON® rotary seals and gaskets are more durable than
ordinary bearing materials under various operation medium
conditions, such as dry friction, water lubrication (clear water or
water containing sand and shale), oil lubrication and grease
lubrication, etc. and even the operation condition of impulsive
loads. INDRON® oil and gas sealing material has excellent
mechanical properties, good rigidity, toughness, hardness, wear
resistance, small permanent compression set, excellent high and low
temperature resistance, and excellent aging resistance. It is
mainly used to prevent lubricating oil from leaking out or oil mist
overflowing in the oil tank.
What bearing materials are more suitable as the materials used for
water pump guide bearings, Babbitt alloy, rubber, ceramics or new
polymer materials? It is advisable to take account of the
lubrication requirements, use environment and maintenance cycle of
the equipment.
