A) ) Fitting snap rings
One side of the “Benzing” snap rings (1) has a round-
ed edge and the other a sharp edge.
For maximum grip the rounded part needs to be fac-
ing towards the element to be held (2), with the sharp
edges on the outside.
B) Joint pivot pins
There are a large number of pivot pins, usually con-
nected to rods, that need to be able to move in vari-
ous directions.
A typical situation has the pin (3) fixed by a self-lock-
ing nut (4) with two anti-friction washers (5) in
between the pin (3) and the support element, and
between this and the nut (4).
Since these are joints, the nut must never be tight-
ened completely but only so much that it can ensure
the free rotational movement of the pin on its axis
without, however, creating excessive free play which
could result in the parts concerned becoming mis-
aligned and failing to work correctly.
