SKF spherical roller bearings –leading in design

Durable cagedesign Steel and brass cages are strong aswell as tolerant tohigh temperaturesand all lubricants.Small and mediumsize bearings havewindow-type steelcages, larger sizes have machineddouble prongedbrass or steelcages. CA design With symmetricalrollers. The innerring centred guide ring centres the onepiece, doublepronged machined cage of brass or steel. The inner ringhas retainingflanges.

Standard bearings: a unique combination of design features

CC design With symmetricalrollers, two win-dow-type steelcages which are inner ring centred via a floating guidering between thetwo roller rows.

All SKF spherical roller bearings havefeatures in common which are unique in the market: •symmetrical rollers•special roller profile •self-guiding rollers – an SKF patent •floating guide ring between the tworows of rollers•bearing components dimensionallystabilised for high temperatures•metallic cagesTo facilitate efficient bearing lubricationSKF standard spherical roller bearings are provided with three lubrication holes in the outer ring, mostly in combinationwith an annular groove. Depending on size and series, standard SKF spher-ical roller bearings are basically made in three different designs:•E design•CC design •CA design

E design The bearings of this design have sym-metrical rollers, twohardened window- type steel cagescentred on the innerring, a flangelessinner ring and a floating guide ringbetween the tworoller rows. E designCC design
