Abstract
A bearing assembly can be releasably secured relative to an outer housing of a rotating control device without using fluid pressure. An example method includes inserting the bearing assembly into an outer housing to outwardly displace a latch engagement member. The engagement member is inwardly biased without fluid pressure, such as with a spring. The assembly is moved to an operative position in the outer housing, at which the inwardly-biased engagement member displaces inwardly to engage a recess on the bearing assembly. Fluid pressure may subsequently be used once the bearing assembly is latched, to optionally help maintain the engagement member in the recess or to move the engagement member out of the recess to unlatch the bearing assembly.
