30x72x19 mm GPZ 1306 self-aligning ball bearing is suitable for arrangements where small angular misalignment between the shaft and housing needs to be accommodated.
30x47x11 mm ZKL 51106 thrust ball bearing is designed to carry axial load in one direction. It is used where force acting along the shaft axis must be reliably supported.
30x62x16 mm MGM 1206 self-aligning ball bearing with two rows of balls compensates minor shaft-to-housing misalignment. It is intended mainly for radial loads and limited axial loads in both directions.
