| COB 070 SELF-LUBRICATING BIMETAL
BEARINGS |
| The basement of this product is superior low-carbon
steel, it sintered copper-forums alloy on the surface in which
the solid lubricant is spread uniformly. After oil-impregnated
processing, this product maintains a low friction coefficient
and it also has good properties of self-lubricating, anti-abrasion
anti-occlusion, etc. The applications of this kind of products
are high-loaded and without oil. |

| COB 072 SELF-LUBRICATING BIMETAL
BEARINGS |
| The basement of this product is superior low-carbon
steel, it sintered bronze alloy on the surface in which the
solid lubricant is spread uniformly. The alloy layer can be
covered a film of solid lubricant as actual requirement. This
product is with low friction coefficient and has good properties
of self-lubricating, anti-abrasion anti-occlusion, etc. It can
be used under high load and in contaminative water, etc. |
