The present invention, a drill shank (7) axially set a location, at least to reduce the stress pulses returning from the rock one axial piston (39a, 39b), an axial bearing 18, a rock drilling comprising a drill having a It relates to (5). The axial bearing comprises a detachable module (21a, 21b) form a single component from one installation direction. The axial bearing module comprises all the necessary seals (42a, 42b), the bearing surfaces (40a, 40b), and the module frame (38a, 37b). Shaft supporting force (FA, FB) caused by the operation of the orientation bearing is passed directly to at least the axial bearing 18, a part of the main body 11 of the rock drilling drill machine uniform in by the support means 43 of the module frame do.
