The Torrington Company (hereinafter referred to as “Torrington”), part of worldwide Ingersoll-Rand, is a bearing and automotive component supplier of international stature. Its global presence in North America, Europe, Australia, South America and the Far East, plus joint ventures in Japan, The People’s Republic of China, and Europe, support customer operations around the world.

Torrington began manufacturing bearings in the early 1900s and now produces every basic type of precision ground anti- friction bearing, as well as many precision components for other mechanisms. Torrington’s wholly owned subsidiary, Kilian Manufacturing Corporation, produces lighter duty machined bearings. Torrington’s merger with Fafnir Bearing, founded in 1911 and recognized as one of the world’s major suppliers of precision bearings and housed units, has further strengthened Torrington’s leadership position as a broad line supplier to the world’s industries.

Torrington’s world leadership position in an automotive component technology is based on its complete technical ability. This extends from the initial design stages through application analysis, to optimizing the entire manufacturing process. The experience gained from broad design and manufacturing activities is available to our customers through Torrington’s resident engineers and field sales engineers in all parts of the world.

As Torrington enters the 21st century, it has dedicated its capabilities and resources — its people, facilities, systems and technologies — to two goals:

  • producing world-class products.

  • assuring total customer satisfaction.

TORRINGTON IS AT HOME AROUND THE WORLD To support its sales and service activities, Torrington has:

  • Over 20 manufacturing plants on five continents.

  • Over 40 district sales engineering offices throughout the world.

  • Warehouses throughout the U.S.A., Canada and Germany, with interlinking computerized inventory control.

  • Extensive capabilities in metric and inch bearings.

  • Technical resources for customer assistance.

For new concepts of the future, for the challenges faced by industry, Torrington offers in-depth design assistance and multinational supply capability for products that are made to identical standards worldwide.


We are committed to providing our customers with maximum service and quality. Included in this commitment is a concern for the suitability of the bearing selected for any application. Only those with sufficient engineering training and technical compe- tence to interpret and apply the data and principles involved should make the final selection of a bearing. The part number in this catalog describes only the dimensions. The part number of the product supplied may differ than those listed in these pages.


This catalog contains dimensions, tolerances and load ratings, as well as an engineering section describing fitting practices for shafts and housings, internal clearances, materials and other features of superprecision bearings. It is not to be considered as containing sufficient data for reliable bearing design and selection for all applications. It can, however, provide valuable assistance in the initial consideration of the type and characteristics of the bearing which may be most suitable for particular needs.

Although all data in this catalog has been carefully compiled to make the information as complete as possible, Torrington assumes no liability to any company or person for any damages, direct or indirect, to property or person, based on information contained in this publication.


Dimension and load rating data for the various types and styles of bearings is organized by size. There is also a numeric/alpha listing of product designation codes in the front of the catalog.

ISO, DIN, and “ABMA”*, as used in this catalog, refer to the International Organization for Standardization, Deutsches Institut für Normung EV and the American Bearing Manufacturers Association.


Fafnir introduced its superprecision bearings, developed specifically for machine tool applications, in 1935. Since that time our engineers, designers, metallurgists and skilled machinists, utilizing state-of-the-art process technology have made improve- ments in their design, material, lubrication, and manufacturing processes. The result is a line of Fafnir superprecision bearings capable of higher speeds, greater reliability, and wider versatility.

As part of our on-going research, development and testing program, our engineers analyze their client’s application problems using sophisticated computers and software which enable them to:

  • recommend the precise type and size of bearing that will give optimum performance under a variety of conditions.

  • predict the probable service life of all bearings with consider- able accuracy.

All of the superprecision bearings listed in this catalog embody the same high standards of precision and quality which have made the FAFNIR name synonymous with bearing excellence throughout the world.
