1) Situation prior to World War II
It is believed that bearings were first introduced in Japan around
1910. With the onset of WWI in 1914, the demand for domestic bearing
production was created, and as a result numerous Japanese bearing manufacturers
were established during and shortly after WWI. The first Japanese-made
bearing was manufactured in 1916. Japanese bearing development and production
expanded rapidly during the period through WWII, fueled mainly by demand
for military applications.

2) Postwar development
Although restrictions on production and investment were placed on Japan’s
bearing industry for a short period following the war, it thereafter
proceeded to grow in step with private manufacturing industries such
as the automobile and home appliance industries. In 1952 the first streamlining
of the bearing industry began, and in the latter half of the 1950s,
such streamlining efforts were intensified, government support based
on legislation was received, and the groundwork for strong growth was
laid. In 1965 new JIS standards conforming to ISO standards were established,
and trade began to expand. In the 70s and 80s, trade friction with the
West erupted, but Japan’s bearing industry for its part was able
to resolve this problem through establishing order in exports, deepening
mutual understanding through dialogue with Western counterparts, and
expanding overseas production.

3-1. Globalization
In the 1970s, Japan’s bearing industry began setting up overseas
production bases—one of the first Japanese industries to begin doing
so—and since 1985, the level of investment in overseas production
has expanded dramatically. Although the original purpose of shifting production
abroad was to alleviate trade friction, in recent years the purposes have
been to achieve lower production costs, etc. In addition, Japanese bearing
makers have begun setting up overseas R&D centers to support these
overseas production bases. The value of annual bearing production around
the world by Japanese bearing makers is approximately 800 billion yen.
While there are no formal statistics, the total worldwide value of bearing
production is estimated to be roughly more than 2 trillion yen, and from
this we can conclude that bearings produced by Japanese bearing makers
account for roughly one-third of the world’s total bearing production.
Relationships with counterpart bearing industries in the West are now characterized
by harmony and cooperation in contrast to former friction and confrontation.
Today the JBIA participates in top-level and specialist-level meetings
with the American Bearing Manufacturers Association and European Bearing
Industry Federation on a regular basis to exchange information and views
on issues of common concern and to carry out joint work on such tasks as
the preparation of statistics, formation of countermeasures for environmental
problems and imitation products, and consideration of measures to meet
automotive industry trends.

3-2. Modularization and diversification
Japanese bearing makers are currently striving to create unit products
and diversify product lineups. By combining bearings with peripheral
parts, bearing makers are creating unit products with a single independent
function while also improving compactness and ease of installation and
reducing weight. Also, in order to meet the varied needs of high-tech
industries, they are diversifying product lineups by developing such
products as ball screws, linear guides, constant-velocity joints, electric
power steering, and continually variable transmissions (CVT) through
the application of bearing-related technology.

3-3. Technical trends
Bearing makers are developing new technology with the aim of further
improving production efficiency and protecting the environment. To meet
customers’ requirements, they are carrying out bearing-related
research and the development of application technology in order to create
bearings with improved compactness, reduced weight, greater speed capability,
higher precision, longer life, and greater ability to perform satisfactorily
in severe usage environments, such as extremely low and high temperatures
and vacuums, as found in outer space, etc. In addition, bearing makers
are providing aggressive technical service to customers from development
through mass production to meet their needs during all stages.
