The auger swivel is used in the guided auger boring
process where it is placed between the pilot rods
and auger casing to prevent the rods rotating as
they enter the reception pit. This means the swivel
is normally in compression, unlike an HDD swivel.
There are currently two sizes of swivel, 121mm
(30T) and 219mm (83T). End fittings can be
manufactured to customer requirement but have
typically been male hexagon connections on the
shaft and either female hex or casing female
threads on the body.
Field trials are still underway but results have been
very encouraging so far.
Both swivels feature our patented sealing system,
external power greasing point, top class branded
bearings and are manufactured from high tensile
