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

  • custom high temperature, high pressure configurations with low leakage and low friction

  • carbon rings with metallic energizers

  • custom butterfly disk piston rings for air control valves with low leakage and very low friction to improve valve closing margins

  • free floating bi-directional pressure energized rings

  • thermal growth matched ring assemblies for small to large horsepower turbine engine shafts for very low operational leakage and long field life

  • mechanical face seals for gases and fluids that are pressure balanced
