What S.I.R. - SOCIETÀ ITALIANA RIDUTTORI S.R.L. does

S.I.R. - Società Italiana Riduttori S.r.l. (SIR) is an Italian specialist manufacturer of electric linear actuators, worm gearmotors, and telescopic columns serving industrial original equipment manufacturer (OEM) customers across multiple verticals. Founded in 1986 in Cermano (Milan) initially as a gearbox producer, the company was acquired by Amer Group in 1993 and relocated to Valdagno (Vicenza), where it pivoted toward custom linear motion systems. The product portfolio spans ten actuator families covering force ranges from 500N to 15,000N (S-LINE through XXL-LINE, SIGARO-LINE, COMPACT-LINE, FLEXI-LINE, RAMB-01-LINE), the RAO-LINE gearmotor family, and telescopic columns (L-SCOPIC, R-SCOPIC, AI-LIFT) — complemented by electric control boards developed with sister company Italsea.

SIR operates a 100% custom, co-design business model in which engineering teams collaborate directly with OEM customers to produce tailored motion components rather than catalog products. End markets include industrial automation and AGVs, agricultural machinery, marine and yacht equipment, medical devices, professional cleaning machines, food processing equipment, and building automation. Recent product development has emphasized higher-force (XXL-LINE) and cobot-targeted (AI-LIFT) variants.

The company is a wholly-owned subsidiary of Amer Group, a privately held Italian industrial conglomerate founded in 1974 and comprising ten operating companies and one brand (including Amer, Italsea, NSM, Schumo, Baumeister & Schack, Antamatic, and regional entities in the USA, India, and China). Amer Group's 550 employees operate from 40,000 square meters of production facilities across five plants, producing over one million units per year with exports to 89 countries. SIR's commercial reach is materially extended through Amer Group's owned distribution infrastructure in North America (Amer Electric Motion, Minnesota), India (Amer NSM India, Pune), and China (Amer Motion Changzhou). The business is not publicly listed, has no disclosed revenue, and operates on a quote-based, multi-year contract pricing model.
