SKF – the knowledge engineering company From one simple but inspired solution to a misalignment problem in a textile mill in Sweden, and fifteen employees in 1907, SKF has grown to become a global industrial knowledge leader. Over the years, we have built on our expertise in bearings, extending it to seals, mechatronics, services and lubrication systems.
Working closely with you Our objective is to help our customers improve productivity, minimize maintenance, achieve higher energy and resource efficiency, and optimize designs for long service life and reliability. Innovative solutions Whether the application is linear or rotary or a combination, SKF engineers can work with you at each stage of the asset life cycle to improve machine performance by looking at the entire application.
Demanding applications and environments require special solutions Applications in industries like food and everage, pharmaceutical, chemical and b hydrocarbon processing or medical require components that can provide high operational reliability and long service life. SKF stainless steel deep groove ball bear ings are manufactured to both withstand tough application requirements and to be the first choice when moisture, corrosive or abrasive materials are present.
B SKF stainless steel bearings for increased reliability SKF stainless steel deep groove ball bearings († fig. 1) are corrosion resistant when exposed to moisture and several other media. They can accommodate radial loads and axial loads acting in both directions. SKF stainless steel deep groove ball bearings have a lower load carrying capacity than same-sized bearings made of high chromium steel. The bearings are available open or capped (with seals or shields) and with or without a flange.
Industry focus: Food and beverage Food and beverage industry regulation is placing ever greater demands on safe food production. Food grade and optically detectable components are some of the supporting developments being applied to bearings to meet HACCP and other food safety management systems and regulation requirements. Recalls are often being initiated because of very small parts of metal or plastic in food.

Bearing data – designs SKF stainless steel deep groove ball bearings are available for shaft diameters from 0,6 to 50 mm. Other sizes may also be available, please contact the SKF application engineering service. Also, a range of inch series bearings is available. Fig. 3 a b c d Sealing solutions Shields Shields identified by the designation suffix Z typically have an extension in the shield bore to form a long, narrow gap with the land of the inner ring shoulder.
B Cages Fig. 5 The bearings are equipped with a stamped stainless steel cage as standard. The following standard cage types can be supplied: • Ribbon type, ball centred († fig. 5a) • Riveted, ball centred († fig. 5b) • Snap type, ball centred († fig. 5c) Injection moulded, ball centred († fig. 5d) polymer cages made of fibre reinforced polyamide 66 may also be available. For additional information about these cages, contact the SKF engineering service.
Bearing data – general Table 2 Dimensions The boundary dimensions of metric stainless steel deep groove ball bearings conform to ISO 15-1998, except for bearings with a WBB1 prefix or an X suffix. Inch series stainless steel deep groove ball bearings conform to ANSI/AFBMA Std. 12.2-1992. Tolerances All stainless steel deep groove ball bearings are manufactured as standard to Normal tolerances corresponding to ISO 492-2002.
Designations The designations for SKF stainless steel deep groove ball bearings follow the basic SKF designation system except for inch types. However, the prefix “W” has been implemented to indicate that the material is stainless steel. For additional information, refer to the SKF rolling bearings catalogue or the SKF Interactive Engineering Catalogue available online at www.skf.com.
