| COB 090(FB090)
WRAPPED BRONZE BEARINGS |
| It is made of high
density copper alloy with special formulations, rolled it is
made of high quality low-carbon steel strip, rolled and sintered
with lozenge or spherical oil indentations on surface. It is
with high density, good load capacity and wear-resistance. It
is used in lifting machinery, construction machinery and mining
machinery etc. |

WRAPPED BRONZE BEARINGS |
| It is improved from cob090 with
special solid-lubricants imbedded into lozenge oil indentation
on surface. It is with very low coefficient of friction, good
wear-resistance and can still work under the condition of no
oil or little oil. |
