Mold Components - Self-Lubricating Shoulder Bushings

These press fit self-lubricating bushings are manufactured from high quality self lubricated aluminum bronze material and are ideally suited for running with commercial and precision posts.

Self-lubricating bushings contain graphite plugs which are impregnated with oil. When the bushings reach 80-90°F 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.
