Designation of a locknut MSA with d1 = M80x2: Locknut MSA 80.2
The admissable operating loads specified in the table are guidline values calculated with a safety margin of 1,6.
under static stress relative to the minimum yield point
under dynamic stress relative to the minimum alternate strength
The locknuts of series MSA with reduced contact surface and in some cases smaller outside diameters relative to the MSA series are particulary suited for mounting angular ball bearings and cylinder roller bearings of ISO diameter series 9.
