Upper bearing - ball raced - 14 mm Ø

Upper bearing - ball raced. For a swing rig with a 14 mm Ø mast. The 15 mm ID x 21 mm OD bearing is supplied with a bearing housing so it fits the mast snugly. The ball race minimise the friction of this item and permits much freer rotation in light airs than the PTFE bearing.

Suitable for use on all SAILSetc Marbleheads with swing rigs where there is a recess in the deck large enough for the outer diameter of the ball race (21 mm).

Use this bearing with the mast/deck blocks (items 139-3021 or 139-3022) to permit the rig to be raked incrementally to suit different conditions.

Replacement bearings - choose BF-12B from the SPARES section of this website.
