Demountable Self-Lubricating Bushings

详情

Self-lubricating bushings contain graphite plugs which are 
impregnated with oil. When the bushings reach ****0F as a result 
of friction between the bushing and guide post, oil is drawn from the 
plug thus lubricating the wear surface. A dark smear pattern is created 
on the wear surface as the oil and graphite are imbedded into the 
bronze or steel grain. This provides the lubrication necessary for 
continuous performance of the tool.
