We describe an elastic teeter bearing (3c) for a rotor (3b), particularly in an aircraft (1), comprising, rotatably arranged on an rotational axis (RA) of said rotor (3b):a teeter beam (3d), configured for attaching at least two rotor blades (3b1, 3b2) thereto on opposing sides thereof, said teeter beam (3d) being devised for performing a teetering motion with respect to said rotational axis (RA) and having at least two first lugs (3j) arranged on opposite sides at a first distance with respect to said rotational axis (RA);a hub piece (3f) located below said teeter beam (3d), said hub piece (3f) having at least two arms (3g1, 3g2) that extend outwardly in a radial direction with respect to said rotational axis (RA), each of said arms (3g1, 3g2) having a second lug (3l) arranged at a second distance with respect to said rotational axis (RA);a bridge piece (3h) located above said teeter beam (3d), said bridge piece (3h) having at least two arms that extend outwardly in a radial direction with respect to said rotational axis (RA), each of said arms having a third lug (3m) arranged at a third distance with respect to said rotational axis (RA);wherein said first to third lugs (3j, 3l, 3m) are parallel or angled with respect to said rotational axis (RA), such that respective connecting pins (3n) which pass through said first to third lugs (3j, 3l, 3m) on either side of said rotational axis (RA) are parallel or, in the case of angled lugs, obliquely oriented with respect to said rotational axis (RA); andwherein a pair of elastic bushings (3k1, 3k2) are arranged on each of said connecting pins (3n) between said first lug (3j) and said second lug (3l) and between said first lug (3j) an said third lug (3m), respectively.
