Attachment holes for studs
The holes in the adjacent part of machinery to accommodate the stud or eccentric collar of a cam follower should be machined to tolerance class H7.
If the requisite tightening torque for the hexagonal nut (table 1) cannot be achieved or the cam followers are subjected to shock loads, the stud or eccentric collar should be mounted with an interference fit. The lead-in chamfer of the holes should be ≤ 0,5 x 45°.
