Fig. 7.4 Example diagram of installation with knuckle eye
CAUTION
If a shaft with an overly small diameter is used, the bearing of the knuckle eye will be
subjected to linear load. This subjects the inner bearing shell to excessive load, which can
lead to damage and, if forces are high, can cause the knuckle eye bearing to break.
Select the shaft as recommended in the mounting instructions.
2. Distance between knuckle eye and shaft bearing
The shaft support must allow for suitable play between the knuckle eye and the shaft
bearing.
CAUTION
If there is too much distance between the knuckle eye and the shaft bearing, this generates
bending moments in the shaft, causing it to deform.
This deformation puts strain on points of the edges of the inner bearing shell, causing the
knuckle eye or shaft to suffer damage or break.
Select the play as recommended in the mounting instructions.
