What Oiles does

Oiles Industry Corporation (TSE Prime: 6282), founded in 1952 and headquartered in Fujisawa, Japan, is a specialty manufacturer of self-lubricating bearings and seismic isolation/damping devices. The company operates two core technology pillars — tribology (friction, wear, lubrication) and damping (vibration control) — developed over 70+ years and backed by 3,572 industrial property rights. Its product portfolio spans oil-less bearings in metal, resin, and multi-layer composite configurations; air bearings for ultra-precision semiconductor manufacturing equipment; and seismic isolation/damping devices for buildings and bridges, including LRB (lead rubber bearings), RB (natural rubber laminated bearings), VWD viscous wall dampers, and WFD friction wall dampers. Manufacturing is split across four domestic plants: Fujisawa (mother factory and R&D), Ashikaga (sole seismic isolation facility with a 4,000-ton biaxial structural testing machine), Shiga (only domestic multi-layer bearing plant), and Oita (large resin bearings).

The company generates revenue through three hardware-sales business segments. Bearing Products (¥50.17 billion, ~74.2% of FY2026 consolidated sales) covers oil-less and air bearings sold into automotive (world No. 1 share in Oiles PS Bearings for strut-type suspensions), industrial machinery, semiconductor manufacturing, energy, and general manufacturing customers. Structural Products (¥11.02 billion, ~16.3%) supplies seismic isolation bearings and dampers for buildings and bridges, including high-profile projects such as the Kanmon Bridge and Aso Medical Center, which withstood the 2016 Kumamoto Earthquake through 90cm of deformation. Building Equipment (¥5.67 billion, ~8.4%) flows through group company OILES ECO and covers smoke exhaust and ventilation window operators.

The go-to-market is a direct enterprise sales model organized by product division (General Bearing, Automotive Bearing, Seismic/Damping), with branch offices covering all major Japanese industrial regions and 8 overseas subsidiaries spanning North America, Europe, and Asia. Approximately 30%+ of consolidated revenue is generated overseas. FY2026 consolidated revenue was ¥67.6 billion with ¥6.9 billion in operating profit (~10.2% margin). Headcount stands at 2,577 consolidated employees (8 overseas group companies included). The company is publicly listed on TSE Prime Market (since April 2022), has no identified parent company, and has not pursued external funding rounds.

Core offering

Oiles is a Japanese manufacturer that produces self-lubricating oil-less bearings (metal, resin, and multi-layer composite bearings), air bearings for ultra-precision non-contact rotation used in semiconductor manufacturing equipment, and seismic isolation/vibration control devices (LRB, RB, dampers) for bridges and buildings. The company also markets residential exterior blinds (BRIIL) and smoke ventilation systems through group company Oiles ECO.

Product overview

Oiles (オイレス工業株式会社) is a comprehensive manufacturer of self-lubricating bearings and seismic isolation/vibration control systems. The product portfolio centers on three core areas: (1) Oiles Bearings including metal, resin, and multi-layer composite bearings, plus specialized Air Bearings for ultra-precision applications; (2) Seismic Isolation and Vibration Control Devices for bridges (LRB, RB, BM-S, HPB, cable dampers) and buildings (SSR, LRB-S, LRB, RB-S, VWD, WFD, VFD, extraction mechanisms); and (3) Smoke Ventilation and Air Conditioning Systems (Oiles ECO). The company operates production bases in Fujisawa (mother factory for bearings and air bearings), Ashikaga (seismic isolation devices with 4,000-ton testing equipment), Shiga (multi-layer bearings), and Oita (large resin bearings), with research and development centered at the Fujisawa facility.
