No need because your bearing is a supply and then imagine that it is at 0.
Otherwise tolerance in general for this type of Ø we use g6 or m6 possibly.
After obviously you need a circlip type stop or notch nut.
Hello
The H7/m6 torque is not necessarily tight.
For a Ø12 for example, there can be a play of 11μm so the stop element in mandatory translation as specified by @ronathan . Unless I'm mistaken, the bearing on its inner ring is not in H7 quality, so probably even more play.
