Kaydon Reali-Slim® open bearings

KA series
Type A – angular contact

A deep groove bearing with reduced shoulder on one side of inner or outer race ball path. Snapover assembly permits use of a one-piece circular pocket ring separator and greater ball complement. These bearings will accept radial load and single direction thrust load and are normally used in conjunction with another bearing of similar construction. Type A bearings require the application of thrust to establish contact angle.

Notes
1 Capacities listed are not simultaneous. For combined loading see discussion of Bearing Selection and Load Analysis in the Kaydon Reali-Slim® bearing catalog. Dynamic capacities are based upon 1 million revolutions of L10 life. Published capacities do not apply to hybrid series bearings P, X, and Y. Contact Kaydon product engineering for values.
2 Static capacities are non-brinell limits based on rigid support from the shaft and housing.
3 ISO Radial ratings are calculated per ISO 281:1990. They are included for comparison only.
4 "F" is the maximum shaft or housing fillet radius the bearing corners will clear.
