| 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. |
