The sealing surface is protected by a spherical labyrinth ring (5) which is also concentric with the centre of pivot and with a matching surface in a machined housing (1). The rotating sealing elements (3 and 4) are positioned and secured to the bearing by adaptor sleeves (6 and 7), and the bearing is located within the housing using a spacer (9).
