Products
Carbon/Graphite Parts – bearings, bushings, rings, seals, spacers, carriers, vanes, rotors, housings, fixtures, nozzles
Seals – face seals, controlled clearance seals, circumferential seals, labyrinth seals, piston rings, ceramic seals
Other Hardware – housings, bands, bearings, rotors, retainers
Size experience ranges from 0.050-inch outer diameter to 10-inch main shaft seals. We have manufactured carbon rings with an axial thickness as small as 0.015 inch. We manufacture mechanical face seals for gases and fluids to helium light band flatness (0.000034-inch carbon face flatness). We also manufacture metallic face seal rotors to helium light band flatness (0.000034 inch). We are capable of holding 0.0005-inch tolerances on up to 10-inch carbon rings.
Services
New parts/designs:
Provide a sketch of the part and our engineers will help you select a material, review tolerances, and provide recommendations. Once your design is complete, we will manufacture the part at our facility.
Specialties
