INDRON® 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.
COMMON GUIDE BEARING MATERIALS
| Bearing type | INDRON bearing | AR bearing | Ceramic bearing | Rubber bearing | Babbitt alloy bearing |
| Characteristics | The performance is close thordon, which can use more equipment assembly methods. In addition to traditional installations by freezing and pressurizing. It can also be installed by coating reactive thermal polymerization Dx and cold sticking. | Good wear resistance and impact resistance. The bearing hardness is high; the shaft sleeve is easy to wear; the temperature difference changes greatly; there will be the risk of shelling; the price is high. | Wear-resistant, heat-resistant, corrosion-resistant, lubricated by pump circulating water, capable of dry grinding for a short time, high requirement on accuracy in processing and assembly, fragile and the most expensive. | It has a long history and mature manufacturing process, featured by wear resistance, anti-seismic, impact resistance, convenient assembly/disassembly and low price (only 20% of ceramic bearings price) | Wear resistance and impact resistance require a set of more complicated sealing and lubricating devices and mechanisms. |
| Lubricating requirements | Clean water can be used for lubrication or 150s dry start according to the material grades. | Dry start more than 180S without clean water lubrication. | It can be lubricated by pumping medium without special clean water lubrication. | Clean industrial water | Grease lubrication requires a grease supply lubrication system. |
| Working temperature | ≤70ºC | ≥273ºC | The bearing itself can withstand the temperature of 1,400ºC | ≤50ºC | ≤65ºC Short time up to 80ºC |
| Application site | For pumping stations short of clean water or pumping stations requiring short-term dry friction, hRBR grade is suitable for water quality with moderate sediment content. | Pumping stations without clean water or pumping stations requiring dry friction of more than 180S. | Pumping stations without clean water or pumping stations requiring short-term dry friction. | Extensive application in any pumping stations with clean water sources. | The liquid of the pump itself cannot be used for bearing lubrication in the pumping station. |
