Strong Points
Self-lubricating bushings contain graphite plugs which are
impregnated with oil. When the bushings reach 80-90¡ãF
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 fit into location
and seat flush 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. Can be used low,
middle and high load. When under high load, wear peformance
degrades accordingly. It's a general-purpose product and be
applied under low or high pressure, low or high temperature,
and oil, water or dry lubrication. Can be applied in consistent
cast machine, rolling machine, conveyor equipment; plastic
injection machine, high voltage switch; hoisting supporter,
hydraulic gate supporter; paper-making machine, automobile
die etc.
