The Self-Aligning Ball Bearing has had such an impact on
industrial development during the latest 90 years that it is
widely considered as one of the most important industrial
products invented during the 20th century. Thanks to ingeni-
ous engineering this SKF invention offers features that are
still unmatched in the bearing world:
HIGH SPEED PERFORMANCE
High machine productivity
The SKF Self-Aligning Ball Bearing has the lowest start-up
and operational friction of all rolling bearings. In practical
terms this means that the bearing has an unparalleled speed
range.
MINIMUM MAINTENANCE Fewer stoppages
Less grease usage
Lower life cycle cost
Only a small amount of lubricant is needed to keep the SKF
Self-Aligning Ball Bearing running efficiently. Its low friction
and favourable design means extended relubrication intervals.
The sealed version is greased for life.
ACCOMMODATES MISALIGNMENT
Lighter and more economic machines
The SKF Self-Aligning Ball Bearing
can accommodate misalignment
better than most other bearing types.
Even when wobbling (caused for
instance by rotating load) the
bearing runs smoothly.

Besides the three basic decisive features, the SKF Self-Aligning
Ball Bearing also offers other important benefits to customers:
LOW VIBRATION AND NOISE LEVELS
Silent machines
Extensive comparative tests show that SKF Self-Aligning Ball
Bearings have the lowest vibration and noise levels because of
their accurate and smooth raceways.
ENVIRONMENTALLY FRIENDLY
Easy recycling and disposal
The low friction and minimal lubricant requirements save
resources and minimise the strain on the environment.
The sealed version provides additional environmental benefits.
SKF is one of the first multinational companies to beISO 14001 certified. This means that environmental issues
are a natural part of all relevant activities and decisions.
Customers can be confident that SKF will always supply
products that are energy efficient, environmentally acceptable,
easy to recycle and safe to dispose of.

WE REDUCE FRICTION TO HELP YOU
MOVE THE WORLD FORWARD
In 1907, Sven Wingqvist invented the Self-Aligning Ball Bearing and laid the
foundation for a new company SKF.
The company produced 2 200 bearings during the first year. Today we make
about 230 000 bearings. Every hour.
SKF is the largest bearing manufacturer in the world with a worldwide network
of 200 manufacturing and sales companies together with some 7 000 authorised
distributors. Over the years, SKF has installed more bearings than any othermanufacturer. This has given us a wealth of knowledge about bearing arrange-
ments that we gladly share with you.
Part of our leadership status is a result of allocating large resources to research
and development. Our driving force is to endeavour to learn more about bearings,
seals and applications than any other company.
Why? Because the more we know about the microscopic world of bearings and
seals, the more you can control your products and processes.
The performance of the Self-Aligning Ball Bearings is evidence of SKFs
continuing ambition to maintain its leading position.
