spacer Kaydon Bearings - RealiSlim open bearings
Kaydon Bearings - KC series
Kaydon Bearings - type X, four point contact bearings

A Conrad assembled bearing designed for applications involving multiple loads. Unique internal geometry permits application of radial load, thrust load in either direction, and moment load, individually or in any combination. A single four-point contact bearing may replace two bearings in many applications.

Notes
1 Capacities listed are not simultaneous. For combined loading see discussion of Bearing Selection and Load Analysis in "Catalog 300—Ball & Roller Bearings". 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 "F" is the maximum shaft or housing fillet radius the bearing corners will clear.
* Contact Kaydon for lead time and minimum purchase requirement.
