Product Description

These demountable self-lubricating bushings are available in 
standard and short profi les and are ideally suited for running with 
commercial and precision posts. They are manufactured from cast 
aluminum bronze material and are prefi tted to the same diameter 
guide posts to ensure that the bushings and guide posts of the same 
diameter are interchangeable.  
 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. The clamp and screws provide four times the holding 
power compared to pressed-in bushings, yet they can be easily 
removed and assembled thus simplifying die building and maintenance.
