Self-Lubricating Guide Post Bushings NAAMS Guide Pin Bushings Oil Free Copper Alloy Bronze Graphite Oilless Guiding Bush
Demountable NAAMS bushings are self-lubricating and are available in guide post and pad styles. These bushings fully conform to the NAAMS, GM, Chrysler and Ford standards. 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. Demountable bushings are tap fi t into location and seat fl ush with the ground face of the punch holder. The bushings are held in place with toe clamps and screws which provide perfect alignment of the bushing with the bore perpendicular to the ground surface of the punch holder. Multipe standard clamps are available
