771045 BALL BEARING DOUBLE ROW, DEEP GROOVE NO.1219K

This design of bearing utilizes two rows of balls with the inner ring having two deep groove raceways while the outer ring has a single continuous spherical raceway. This permits the inner and outer rings to be misaligned relative to each other through a comparatively large angle without imposing moment loads upon the balls. This bearing is frequently used when the inner ring is to be mounted upon an adapter sleeve or when conditions in the machine make it difficult to assure accurate alignment of the inner and outer rings. The boundary dimensions of 1200 and 1300 series are identical with those of 6200 and 6300 single row deep groove bearings. Due to the small contact angle, the thrust capacity of these bearings is limited. Series 1200K–1/12 Tapered Bore. These types of bearings have to be used with adapter sleeves.
