Excellence in the development and production of suspension springs

RNA occupies an outstanding position in the automotive spring market, where it is today the largest manufacturer of original springs in South America.

RNA’s history begins in 1932, when Fabrini, a suspension springs manufacturer, was founded in São Paulo to serve the aftermarket.

In 1957 Fabrini became a supplier of the first automakers installed in Brazil. 3 years later, Fabrini builds a 20 thousand square meter plant in São Bernardo do Campo.

At the same time Cimebra, founded in 1956 and 11 years later becoming a supplier for automakers, was acquired by Japan’s NHK-Spring, then a group with more than six decades in activity, world-wide operations and one of the largest springs manufacturer in the world, in addition to its strong presence in various other sectors such as automotive seating, industrial equipment and security and information systems.

In 1996, Fabrini is incorporated by Sanluis Rassini. This group which is based in Mexico and produces breaking and suspension systems, is an original equipment supplier to major automakers in the world and has plants all over the American continent. That was the starting point of the decision to work jointly in the Brazilian market through these two groups, forming RNA: Rassini-NHK Automotive, with two plants, one in São Bernardo do Campo in Sao Paulo state and another one in Nova Iguaçu, in the state of Rio de Janeiro, totalizing 35 thousand square meters of constructed area, built on total area of 55 thousand square meters.

Aprender Project

Every time we learn something, we climb one step, becoming more mature, conscious human beings and responsible for our world. This responsibility is the backbone of the Aprender Project, an idea originated to provide youths the opportunity to climb several steps in their lives.

RNA believes that education and access to information are vital for the development of every human being and their interaction in the society and in the workplace.

This belief led RNA to create the Aprender Project. It consists of English and computer classes, as well as a library and Internet access for around 60 youths, the children of associates and local community inhabitants.
