BS EN 6056 pdf free download. Aerospace series – Rod-end with bearing per EN 4614 with self lubricating liner in corrosion resisting steel with external threaded shank – Dimensions and loads – Inch series.
1 Scope
This European standard specifies the characteristics of adjustable rod-ends consisting of:
— a self-aligning ball bearing with self-lubricating liner (EN 4614);
— a rod-end with threaded shank with an optional longitudinal groove for locking purposes. They are intended for use in fixed or moving parts of the aircraft structure and their control mechanisms.
