Figure 7.15: Connecting rod spherical bearing made
of Delrin ® with snapped-in securing ring. The ball
made of nylon ensures good bearing properties with
low wear even when completely dry.
Figure 7.16: Similar design, but with spin welded
securing ring for high axial loads.
In order to safeguard the clarity of the illustrations, the
axial grooves are not shown in these examples.
Naturally they are to be provided in each case.
