The D1010 is the standard swivel joint with two ball tracks.
It is usually used where large size swivel joints have to
take heavy loads (typically for Emco Wheaton Marine Loading
Arms). Both ball tracks of the carbon steel version are
hardened and polished, giving the swivel joint a high
degree of load capacity and long service life, even
under extreme loads.
The sealing surfaces are plated with stainless steel and
precision-finished to prevent corrosion, ensuring that
the seal that slides along these sealing surfaces is not
damaged and will seal perfectly.
The D1010 swivel joint, made of a special aluminum alloy,
is not supplied with hardened ball tracks due to material
characteristics, therefore it is only suitable for normal
loads. Aluminum swivel joints have no specially plated
seal faces due to the chosen alloy.
