High Temperature Bearing
High Temperature Bearing,Reliable, High-Performance And Efficient
Components
These bearings for dry-lubricated flap valves can be used in the
exhaust gas system, for example for exhaust gas recirculation, the
turbo bypass or in mufflers. It's characterized by high thermal
resistance and the option to be used in conjunction with various
different counter-members.

You benefit from these advantages:
- Quality for modern exhaust gas systems in vehicles
- Perfectly matched graphite materials
- Reliable, high-performance and efficient components
- Simultaneous engineering enables inclusion in development
Features:
- Excellent thermal durability
- Good thermal conductivity
- Resists wetting by molten metals
- Complex shapes can be processed
- Reduces metal sleeve weight
- Various surface modifications and treatments enable a variety of
applications
Due to its ability to resist wetting by molten metals, graphite is
used as a mold material for strip dies, tubular dies, and other
molds used in continuous casting processes for copper and copper
alloys (brass, bronze, and nickel silver), aluminum alloys, cast
iron, precious metals, and a variety of other metals.
Graphite can be used with different continuous casting methods
(horizontal/vertical) and can be produced in a variety of ingot
shapes (including plates, strips, pipes, rods, wire, and contoured
shapes).
With a wide range of grades available, we can select the optimal
grade for a variety of cast metals and alloys.
We manufactures products from structural brands of graphite,
impregnated graphite, antifriction graphite
Graphite has unique properties:
- electrical conductivity;
- heat resistance (sublimation effect);
- poor wettability by many metals;
- strength, anomalously increasing with temperature increasing;
- possibility to work with dry friction (self-lubrication)
Due to its unique properties, graphite products are used in many
industries:
- production of ferrous, non-ferrous and precious metals;
- engineering;
- chemistry, petrochemistry and oil refining;
- glass industry;
- analytical laboratories;
- power engineering and electrical engineering.
