Customized Impregnated Carbon Graphite Bushings High
Self-Lubricating
Description
Graphite bearings can meet the sealing requirements under strong corrosive,
flammable, explosive, and radioactive media due to their
self-lubricating, high-temperature resistance, corrosion
resistance, and other characteristics.
Graphite bearings effectively solve many problems in chemical
machines, and they are excellent for improving working conditions
and raising product quality and productivity.
Graphite bushings are widely used in a variety of pumps, stirring
machines, high temperature-high pressure dyeing machines,
compressors, sealing rings of reactor vessel mechanical seal
components, oxygen generator, piston rings of air-blower, shield
electric machine, submersible motor, instrument, fuel pump, vacuum
pumps, gas compressors, air pumps in pressing machine, Safety
blasting film and plate in chemical devices, panelboard and arc
block in cigarette making machine, etc.
