Product Description

Interference Press Fit Water Guide Bearing

The guide bearing of the full cylinder water pump can be installed by freezing or pressure:

• Due to the high thermal expansion coefficient of INDRON® materials, it is recommended to give priority to installation by freezing (liquid ammonia or dry ice);

When the tooling conditions for installation by freezing are not available, pressure installation can be optional (INDRON® bearing needs to be chamfered as required then).

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.
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	≤65ºCShort 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.
