Abstract
The present invention relates to a roller chain (10) for a recirculating bearing module (20), intended for an offshore application. The roller chain (10) comprises several rollers (11) which are each fitted onto a shaft (12). The rollers (11) are free to rotate relative to their associated shafts (12). And the cylindrical inner surface (112) of said roller (11) and the outer surface (121) of said shaft (12) define a sealed chamber (15) which is filled with a lubricating fluid. Each shaft (12) is rotationally locked with at least one associated link (13) by means of rotational locking means (16).

Roller chain (10) for a recirculating bearing module (20), intended for offshore application,
- which roller chain (10) comprises several rollers (11) which are each fitted onto a shaft (12),
- each shaft (12) having an outer surface (121) and being connected to an adjacent shaft (12) by two links (13),
- characterized in that said rollers (11), of tubular shape, each comprise:
- a cylindrical outer surface (111), and
- a cylindrical inner surface (112), defining a through-hole (113) into which said shaft (12) is fitted,
- which rollers (11) are free to rotate relative to their associated shafts (12),
- which cylindrical inner surface (112) of said roller (11) and which outer surface (121) of said shaft (12) define a sealed chamber (15) which is filled with a lubricating fluid,
- and in that each shaft (12) is rotationally locked with at least one of said associated links (13) by means of rotational locking means (16).
