Kaydon Reali-Slim® sealed bearings

JU series (double sealed)
Type X – four point contact

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 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 Torque figures shown are for single bearings with standard lubricant at room temperature and under 5 pounds thrust load.
4 "F" is the maximum shaft or housing fillet radius the bearing corners will clear.
* Values apply to bearings loaded up to 20% of their dynamic capacity.
 
Sealed series bearings are supplied with general purpose grease, satisfactory for operating temperatures of -40°F to +250°F (-40°C to +121°C). Other lubricants are available on special order.
