Self-lubricating BearingsCu base
(COB-SRIM 011/016)

COB-SRIM 011 self-lubricating bearingsIt's based on brone alloy of a particular formultaion with sintered bronze layer as its interlayer & the compound of PTFE & Pb as its surface. It offers the property of good self-lubricating, low wear and low frcation,it has made full use of the strong points of metals & polymer materials. It's used in steel metallurgical industry,cement grout pumps and spiral converyers for cement,etc.
COB-SRIM 011 Metallurgical structure

1.PTFE with lead 0.01~0.03mm
2.Porous bronze 0.2~0.3mm
3.Cu backing 0.7~2.3mm

COB-SRIM 016 self-lubricating bearings(Without Pb)It's based on bronze alloy of a particular formu-lation with high density with sintered bronze layer as its interlayer, with the compound of mostly PTFE and other factors. As it's without lead, which makes the bearing lubricating condition cleaner,and in accordance with environmental request.
COB-SRIM 016 Metallurgical structure

1.PTFE with fibre 0.01~0.03mm

2.Porous bronze 0.2~0.3mm
3.Cu backing 0.7~2.3mm

COB-SRIM 011 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.

COB-SRIM 016 Application
1.PTFE & fibre can protect the shaft while in operation. 2.It is suitable for the machine required harmless to people because of Lead-free.
3.Goodload capacity and anti-wear.
4.Bronze and steel have good thermal conductivity.
5.Anti-corrosion because of surface plating.
6.It is widely used in general machines,and suitable for food machine,pharmaceutical machine,tobacco machine etc. It will subsitute SF-1 in future because of environment protection.
