Y-bearings with grub screws in the inner ring are locked in position on the shaft by tightening the two cup point hexagonal grub screws, positioned 120° apart. These bearings are suitable for applications where the direction of rotation is constant or alternating. Two different standard designs are available. Y-bearings in the YAT 2 series have an extended inner ring on one side, and are sealed with the rugged standard integral seal. The outer ring has two lubrication holes as standard. Y-bearings in the YAR 2 series have an extended inner ring on both sides. This reduces the extent to which the inner ring can tilt on the shaft, which enables the bearing to run more smoothly.
These bearings are fitted with the rugged standard integral seal and one of the following flinger options:
• plain sheet steel flingers, designation suffix 2F
• rubberized sheet steel flingers (multiple seal),designation suffix 2RF
The outer ring has two lubrication holes as standard.
