How to choose the sliding bearing for your oil gear pump?
2015-10-14
Sliding Bearings are Bearings whereby the shaft slides in the Bearing.The friction and wear of Sliding Bearings is higher than in Roller Bearings. To reduce friction lubrication is often used.
So it is important to choose the sliding bearing to support your oil gear Pump.Friction can also be reduced by a proper choice of materials. ‘SF-1T Bearing’ material is used this way. This is a special alloy with lubricating properties.
Structure:
1.PTFE with lead 0.01-0.03mm
2.Porous bronze 0.2-0.3mm
3.Steel backing 0.7-2.3mm
4.Tinplating 0.005mm or copper plating 0.008mm
They are composed of a Specially designed surface and is specifically applied for the high PV bushes of oil gear pump.It is to be used in hydrodynamic or boundary lubricating condition of medium or high pressure gear oil pumps such as P=16-25 Mpa,V=3.5-5m/s.It shows the benefits of low friction coefficient,wear resistant and anti-impact properties.At hydrodynamic lubricating,the PV limit reaches to 120N/mm2.m/s.It is the best choice for the bearings of various kinds of gear pumps as well as plunger pumps,vane pumps and so on.
As below pictures from our customers,you can see the application of sliding bearing for the oil gear pump.The shafts are supported in multi-layer bearings that have excellent antifriction properties.
Hope this can help you to choose the sliding bearing for your oil gear pumps.To know more about the sliding bearing and any inquiry of our sliding bearings,pls visit our website:www.slide-bearing.com.
