The current SKF range of suspension bearingsIntroduction

SKFThis catalogue has been drawn up to help customers conceive their suspension systems taking into consideration, right from the early development stages, the wide variety of design options that SKF suspension bearings have to offer. SKFSKFThe SKF suspension bearings shown in this catalogue are all currently in series production. For each bearing, the overall dimensions and fitting conditions are shown.For further information, please contact SKF team.

Application General InformationVarious types of ball-set to suit all applications

Normal ball-set, mainly for use with internally centred bearings

Reversed ball-set, mainly for use with externally centred bearings

Inclined ball-set, for reduction of radial loads acting on the ball-set

Axial ball-set, for space optimisation and excellent load carrying stability for certain applications where radial loads are limited

October 30, 2007 SKF Group Slide 4

Application General InformationSome typical SKF suspension bearing solutions

SKF

Full metal bearing(additional customer spring seat required)
