I think that these bolts are made so that they break if over torqued to prevent crushing of the bearing and causing it to swell into a barrel shape and reduce the ball clearance.
If the small hole that is visible is all that goes through the bolt then the material selected is the cause of the failure when over torqued.

Bearings will not last long with reduced ball clearance.

The use of the wrong bolt material and torqued to the specified setting may crush the bearing whereas the correct material will stretch and not load the bearing too much using the same torque setting.
