What ROC Carbon Company does
ROC Carbon Company is a Houston-based, family-owned custom manufacturer founded in 1956, specializing in precision-engineered carbon graphite, PTFE composite (ROCBON), and PEEK components for rotating industrial equipment. The company produces segmented seal rings, bearings and bushings, metal-backed seal rings, mechanical seal faces, labyrinth ring seals, and specialty parts for steam turbines, compressors, centrifugal pumps, and industrial fans/blowers. Manufacturing operations are conducted from a single 30,000-square-foot facility in west Houston with capabilities spanning CNC machining, precision waterjet cutting, and lapping to within one helium light band (less than 12 millionths of an inch) for seal surface flatness.
The company operates a direct sales model serving petrochemical plants, refineries, power plants, sugar mills, marine operators, and oil and gas producers through original equipment manufacturers, equipment repair shops, and end-user industrial plants. Revenue is generated through three streams: (1) custom parts manufacturing on a quote-based, per-unit basis; (2) standard replacement parts sold from inventory with same-day delivery; and (3) technical and engineering services including reverse engineering, material grade recommendations, and material identification using XRF analyzers. Pricing is quote-based for custom work, and 24/7/365 emergency response capability supports urgent industrial needs with 24-hour turnaround on critical parts.
ROC maintains a 20,000-part cross-reference database compiled over six decades that enables same-day matching of OEM part numbers to in-stock or quickly producible equivalents. The company has held ISO 9001 certification since 1999 and reports a 98% on-time delivery record since 1990. Materials are enhanced through proprietary impregnation processes using resins, antimony, copper, nickel chrome, and bronze, plus oxidation inhibitors, to tailor corrosion, wear, and thermal performance. Shrink-fit and stress-relieving procedures for assembly of carbon graphite into metal housings address failure modes common to high-speed rotating equipment.
