   "GN 351 rubber buffers are cylindrical rubber-to-metal anti-vibration mounts (rubber bumper, rubber foot, vibration isolator, cylindrical mount): a natural rubber body bonded to steel cover plates, with a threaded stud or a threaded hole on each end.

   "Where the table has two M-rows for the same d1 (40 mm with M8 and M10), the thread is part of the row. The 16 mm size has only EE heights (15, 20) and no stud length printed. Hardness does not change dimensions: every code is offered in 40, 55 and 70 Shore A.",
