1. A bearing assembly for a first pipe that is moveable relative to a second pipe in a fluid delivery system, the bearing assembly comprising:
a unitary main body adapted to be connected to an end of the first pipe, the main body having a central opening for flow of fluid there-through in the fluid delivery system, a central recess formed having a shoulder or flange surrounding the central opening, and a radially extending annular face formed around the central recess having a coaxial seat on the annular face that receives a first thrust ring;
an annular centre swivel adapted to be connected to an end of the second pipe and having a first radially extending face with a coaxial seat to engage the first thrust ring and an opposite radially extending face with a second coaxial seat that receives a second thrust ring, wherein the centre swivel includes: a part that extends axially towards the main body and is received within the central recess of the main body in axial alignment with the central opening for flow of fluid there-through, wherein an end of said part of the centre swivel received within the central recess is located opposite the shoulder or flange surrounding the central opening, and an annular, axially extending boss that extends away from the main body for connection to the end of the second pipe, with said opposite radially extending face extending radially outwardly from the boss; and
a bearing end cap adapted to engage around the second pipe and adapted to be bolted to the main body securing there-between the centre swivel and the first and second thrust rings, the end cap having a seat for the second annular bearing;
wherein the main body has an annular slot forming a first coaxial transverse recess to receive an annular first seal member arranged to seal against a cylindrical outer surface of said part of the centre swivel that extends axially towards the main body and is received within the central recess, and wherein the annular first seal member comprises: a glide seal which abuts the cylindrical outer surface of said part of the centre swivel that extends axially towards the main body, and an O-ring energiser that sits in the annular slot covered by the glide seal.
