Because of the long lifespan of helicopters, all components need to be replaceable. For safety reasons, fasteners should not shake loose under the influence of vibrations. For those two reasons, nearly all components in a helicopter are fixed using locked nuts and bolts. Locking mechanisms used in the R44 are safety pins, safety wire, and adhesives. Plain bearings and ball bearings are either pressed into place, or held in place by a retainer ring and bolts.
