Description

DUB Bronze Base PTFE Composite Bearing Bushings

 

 

Material:      

1.PTFE layer 

2.Porous bronze 

3.Bronze backing 

 

Introduction:   

1,DU-B bushing is tin bronze based with bronze powder inside and PTFE surfaced and filled with anti-high-temperature material. It is very safe and specially used in the place can't stop for repair and can't add oil because of high temperature.

 

2,This is widely used in steel metallurgy industry such as roller grooves of successive casting machines,cement grouting pumps and screw conveyers for cement. It can also be composed in steel housing or fabricated into flanged bushes which can move both in radial and in axial directions.

Application:

1.PTFE and lead can protect the shaft,while the machine in operation.

2.It can be composed in steel housing,or fabricated into flanged bushes

which result in function for montion both on flange and I.D.

3.It is widely used in steel metallurgy industry,such as bushes for foller

grooves of successive casting machines,cement grouting pumps and scrow conveyers of machine .

4.Bronze have good thermal conductivity,it'll divert heat while the machine operating.

5.It can be applied in the machine,working long time,which examine and repair is incapable, because the bronze can lubricate itself.

6.It is used in the feeble acid and alkali condition because of good anti-corrosion of bronze backing.

7.Good load capacity.
