[0041] figure 1 A rock drilling unit 1 that can be set on a drill arm 2 etc. of a rock drilling equipment is shown. The rock drilling unit 1 may include a feed beam 3 on which a rock drilling machine 5 is arranged and moved by means of a feed device 4. The rock drilling machine 5 can be fastened to the bracket 36 and can move in the striking direction A and the return direction B. In addition, the rock drilling machine 5 includes an impact device 6 for generating impact pulses on the drill shank 7 and allowing the impact pulses to pass through the tool 8 to the rock 9. The tool 8 may include one or more drill rods and drill bits. Alternatively, the tool 8 may be a monolithic drill rod, in which case a machine member like the drill shank 7 may be considered to be fixedly connected to its end on the side of the rock drilling machine. Therefore, in this patent application, the drill shank can also refer to the rear end of a monolithic drill rod, etc., and the axial bearing can a...
