Take all expected peak loads into account when dimensioning the solid shaft or the machine shaft.
The solid shaft material must have a minimum yield strength of 360 N/mm

. This ensures that no
permanent deformation occurs due to the clamping force.
Do not use corrosion protection, assembly paste or other coatings on the fitting surfaces of the
shaft, the bushes, the clamping rings or the shrink disc.
Prerequisites
• The solid shaft [6] must be free from burrs, corrosion, lubricants or other foreign bodies.
• The hollow shaft [5], the bushes [3], [7], the clamping ring [4] and the shrink disc [1] must be free
from dirt, grease and oil.
• The solid shaft diameter must be within the following tolerances:
