HI-Tech Carbon Graphite Bearing
Graphite bearing is used in parts in non-oil lubricative machine. Such as the bearings on case-hardened
equipment and colourationequipment in printing and dyeing industry, those are all graphite bearings, it
can avoid problem of pollution by lubricating oil. As the graphite has better wearability .We can machine
various types and process according to designs
Material Specs
Density: ≥1.87g/cm3 Grain size: 325mesh
Compressive strength: 60-85mpa High machining quality
Feature
1. Thermal stability: According to the quench acute thermal using conditions of graphite crucible, we will
specially design the production procedure, so as to ensure the reliability of product quality.
2. Corrosion resistance: Even and fine basic design will delay the erosion of crucible.
3. Impact resistance: Graphite crucible can bear high thermal impact, so any process can be carried out.
4. Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially
its index of acid resistance., and will prolong the service life of graphite crucible.
5. High heat Conduction: High content of fixed carbon ensures the good heat conduction, shorten the time
of dissolution, and remarkably reduce the energy consumption.
6. Control of metal pollution: The component of material under strict control will ensure that graphite
crucible will not pollute the metals when dissolving.
7. Quality stability: The process technology of forming under high pressure and quality guarantee system
will fully ensure the stability of quality
Self-lubricating Sroperties
The self-lubricating properties of carbon graphite and graphite materials, along with stability at elevated
temperatures, and resistance to most chemicals, make these materials well suited to demanding applications.
Graphite materials enable the design engineer to extend the temperature and chemical range, and with the
proper adjuvant, permit the use under cryogenic conditions. Impregnation with resins and metals can be
used to enhance the properties of carbon graphite.
Most of the lubricant material will break up and catch fire under the high temperature, high pressure and
high speed working condition. So most equipment can not use normal lubricant material to improve the
durability.
Therefore, carbon and graphite bearings, piston rings and sealing rings are normally used in mechanism
equipments and these carbon and graphite parts can work at -200 to 200 in corrosive medium and they
can normally revolve with high speed(like 100m/s) without lubricating oil
