A comprehensive catalog of self-lubricating, chemically inert components engineered for the most demanding mechanical applications.
Used in pumps, turbines, fans, and compressors to seal gases, vapors, liquids, powders, and gaseous mixtures. Carbon-graphite is the preferred seal face material because it is self-lubricating, chemically inert, and maintains exceptional flatness due to its high modulus of elasticity.
-55°C to +450°C
Self-Lubricating / Dry Running
FDA-Compliant Grades Available
Chemically Inert, Non-Toxic
Carbon-graphite bearings replace metal bearings in environments where oil/grease lubrication is impossible, prohibited, or insufficient. Since there is no metallic attraction between carbon-graphite and the shaft, these bearings are immune to galling and seizing even under dry running conditions.
Self-Lubricating / Oil-Free
Up to 4+ bars.m/s
Dry, Submerged, Chemical
Immune to Galling & Seizing
Used in rotary vane pumps and compressors, carbon vanes are preferred because they are self-lubricating, chemically inert, and have minimal thermal expansion. This means tight rotor slot clearances can be maintained even at temperatures above 400°C. Carbon gives a fine polish to the cylinder wall, reducing overall wear rates.
Up to 400°C+
Minimal Thermal Expansion
Polishes Cylinder Walls
Oil-Free Delivery
An optimized alternative to soft PTFE and metal ball valve seats for high-temperature applications. Carbon-graphite provides the soft cushion against the ball while maintaining zero-leakage performance and high chemical resistance across a wide range of media.
Up to 600°C (with inhibitor)
Zero-Leakage Performance
High Chemical Resistance
PTFE & Metal Seats
Handle axial loads in pump and motor assemblies. Carbon-graphite thrust bearings perform flawlessly in dry, lubricated, and chemically aggressive conditions. Their self-lubricating nature eliminates the need for external lubrication systems, reducing complexity and maintenance costs.
Axial Load Handling
Dry, Wet, Chemically Aggressive
Used in piston rod sealing and rotating shaft applications where a full ring cannot be installed. The split-ring design allows for easy installation and replacement without dismantling the entire shaft assembly, significantly reducing downtime during maintenance.
No Shaft Dismantling Required
Split-Ring for Easy Replacement
Carbon-graphite steam joints are serviceable in wet, saturated, and superheated steam conditions. They are critical components in rotary joints for paper mills, textile machinery, and steam-heated cylinder systems where reliable sealing under thermal cycling is essential.
Wet, Saturated & Superheated Steam
Reliable Under Thermal Cycling
