"We use igubal® flanged bearings at two positions in the facility: As bearing of the support shell and for the bearing of the retaining device in the support shell. In both cases, the rotary axis lies not below 90° to the screw-on surface. As the screw-on surface is a thin plate, one either had to mill the bearing blocks for the acceptance of glide bushings, or use angle-tolerant flanged roller bearings. The igubal® flange bearings were by far better cost-efficient alternative in comparison. ”
