1 Scope
This Standard specifies boundary dimensions, tolerances, radial internal clearances and specifications for dimension series E, EH, G, GH and K of spherical plain bearing rod ends.
Spherical plain bearing rod ends don’t need to conform to the designs illustrated but compliance is required as regards dimensions, tolerances and radial internal clearances specified.
The dimensions and tolerances specified in this Standard have been selected to permit the design and use of spherical plain bearing rod ends which incorporate radial spherical plain bearings having various sliding material combinations. .(for manufactures’ production, inspection and customers’ acceptance)
This Standard is not apply to the spherical plain bearing rod ends for airframe applications and specific spherical plain baring rod ends for direct connection to hydraulic cylinders.
