Multi-Rubber Bearing is the example of Bridgestone's cutting-edge technology with practical safety applications.
Since the founding of Bridgestone, the company principle requires that only the highest quality products be delivered to the market. Our MRB manufacturing line incorporates this Quality First concept.
All production steps from the rubber material procurement, mixing, processing, manufacturing, and inspection are checked for quality, resulting in a continuous supply of premium products.
Accelerated heat-aging tests have confirmed the Bridgestone MRB has the necessary durability.
As a pioneer in the Industry, Bridgestone has been deeply involved in the research and development of seismic isolating rubber bearings.
Bridgestone’s unprecedented number of test results put its MRB on the cutting edge of technology.
Bridgestone offers a complete assortment of bearings to the Industry;
We can produce the ideal seismic isolating system to meet your needs.
Bridgestone started R&D in 1980, and supplied isolators to first seismically isolated buildings in Japan (1982).
In the current stage, accelerating phase to the high and stable growth depend on the world wide market demand.
The Yokohama Plant began operation in july 1938 as a reclaimed rubber plant. When it first opened, it manufactured products such as antivibration rubber in addition to reclaimed rubber. Later,after bicycle tires, golf balls, and other products began to be manufactured at the plant, it was reorganized in 1963 into a plant specialized in non-tire products, known collectivily as chemical and industrials products.
Since its reorganization it has manufactured a wide variety of products for an array of customers, as the main plant in the chemical and industrial products business.
As the center for developing technology for chemical and industrial products, the Chemical & Industrial Technical Center (KTC) was built in April 2000 on the site of the Yokohama Plant, using a baseisolated structure (with multi-rubber bearings installed underground). The Research & Development Center for Chemical & Industrial Products (KRC) was added in November 2007, employing a mid-story isolation structure(with multi-rubber bearings installed between the first and second floors). Bridgestone has thus complated a physical infrastructure for research into new technologies and development of new products to support the chemical and industrial products business in future.
