A mechanical handling system chain pulls heavy print industry paper rolls. The chain has links (1) each with two side-plates (2, 3) linked by bolts (5.1) through bearing cases (8, 9). Each half (8, 9) of the bearing case has a flange (17). The flange, bearing housings and bearing ends (2.1, 3.1) are held together by a flexible case that prevents twisting and displacement of component parts. |
