A bearing assembly having a removable shaft member. The shaft member has a center portion is designed such that rotation of the ball portion of the bearing assembly on the center portion is prevented. A first end portion extends outwardly from one end of the center portion and has a diameter substantially equal to an arcuate portion formed in a first side wall portion of a cavity located at one end of the female connection member. A flat face portion engageable by a wedge member is provided on the first end portion. A locking device is engageable with the first end portion to secure the ball portion against lateral movement in a first direction. A second end portion extends outwardly from the other end of the center portion and has a diameter also substantially equal to a diameter of an arcuate portion in a second side wall portion of the cavity. A flat face is formed on the second end portion which is engageable by another wedge member, thereby securing the male member to the female connection member. Another locking device is engageable on the second end portion to prevent the ball portion of the bearing assembly to prevent lateral movement in a second direction.

A removable shaft member engageable in a ball portion of a bearing assembly which is engageable in an outer end portion of a male connection member of an articulated coupling arrangement used to connect adjacent predetermined ends of a pair of railway cars together in a substantially semipermanent manner, said removable shaft member being further engageable with a pair of radially opposed side wall portions of a cavity formed in an outer end portion of a female connection member of such articulated coupling arrangement, said removable shaft member comprising: (a) a center portion having each of a first predetermined length and a first predetermined diameter adjacent a first end of said center portion and a second predetermined diameter adjacent a second end of said center portion, said center portion being engageable in an aperture formed through such ball portion of such bearing assembly; (b) a first means disposed on said center portion of said shaft member and extending substantially parallel to a longitudinal axis of said shaft member for preventing rotation of such ball portion of such bearing assembly on said center portion of said shaft member; (c) a first end portion having each of a second predetermined length and a third predetermined diameter extending outwardly from said first end of said center portion of said shaft member, said third predetermined diameter being substantially equal to a diameter of an arcuate portion formed in a first side wall portion of such cavity; (d) a first substantially flat face portion formed along at least a portion of said second predetermined length of said first end portion, said flat face portion being engageable by a substantially flat face of a wedge member thereby enabling securement of such male connection member to such female connection member; (e) a second means, having a first portion formed on said first end portion of said shaft member and a second portion engageable with said first portion, for preventing lateral movement of such ball portion of such bearing assembly in a first predetermined direction during operation of such articulated coupling arrangement; (f) a second end portion having each of a third predetermined length and a fourth predetermined diameter extending outwardly from said second end of said center portion of said shaft member, said fourth predetermined diameter being substantially equal to a diameter of an arcuate portion formed in a second side wall portion of such cavity; and (g) a second substantially flat face formed along at least a portion of said third predetermined length of said second end portion, said second flat face portion being engageable by a substantially flat face of a wedge member thereby enabling securement of such male connection member to such female connection member.
