What SILENTFLEX does

Silentflex is a Spanish manufacturer of anti-vibration mounts, silentblocks, and shock absorbers founded in 2000 and headquartered in El Astillero, Cantabria, Spain. The company produces a comprehensive portfolio of metallic and elastomer-based vibration isolation products including wire rope isolators, spring isolators, metal cushion dampers, floating floor systems, and elastic joints, with over 950 standard product references and up to 2,000 custom configurations. Core technology combines stainless steel wire rope construction, metal cushion dampers formed from pressed stainless steel wire, and high-resistance metal springs to deliver documented performance including vibration isolation exceeding 99% for electric transformers and acoustic attenuation up to 55 dB for floating floor systems, across a temperature range of -70°C to +300°C.

The company operates a direct sales motion through regional offices in Spain (HQ), Mexico, France, and Italy, with international business operations extending to the USA, China, Canada, and Dubai. Customer segmentation is horizontal across industrial manufacturing (machine tools, heavy machinery, rotating equipment, presses), transportation and military (trains, naval, armored vehicles), electronics and IT infrastructure (data centers, server cabinets, telecommunication equipment), and energy and utilities (electric transformers, exhaust systems, piping). The company holds ISO 9001 quality certification and supports customers through multi-language digital presence (Spanish, English, French, Russian) and direct technical specialist consultation.

Revenue is generated through hardware sales of standard catalog products and custom-engineered solutions, with quote-based pricing and no publicly disclosed price list. The sales motion is sales-led and consultative, with technical specialists recommending solutions for specific vibration treatment problems. No funding rounds, revenue figures, or headcount disclosures are available, limiting visibility into financial scale. The firmographics layer describes an entity in Cedar Park, United States with 1-10 employees, which appears inconsistent with the 20+ year Spanish parent and likely refers to a US subsidiary or distribution presence.
