Mounting for Angularly Applied Loads
Series 249G2 Swivels Installation 23
Different system configurations require the use of different types of retaining
stops. In all cases, the retaining stops must withstand a shear force equal to or
greater than the forces specified in the following illustrations.
Systems that require the swivels to react angularly to applied tensile and
compressive loads should also take into account the possibility of backlash
between the retaining stops and the swivel jaw. The retaining stops should be
mounted in a manner that will eliminate or minimize this backlash.
