This deep groove ball bearing carries radial and moderate axial loads on a shaft with a 30.0 mm bore, 72.0 mm outside diameter, and 19.0 mm width, weighing 343.0 g. It is a single row design of Generation C construction, fitted with a sheet steel cage (cage code JN) and sealed on both sides (2HRS), which keeps grease inside the bearing and blocks contaminants from entering the raceway. The limiting speed is 9300 1/min. The radial internal clearance is C3, wider than standard, which compensates for tighter fits and thermal expansion during operation without introducing excessive play. Being pre-greased and sealed, this bearing requires no separate lubrication maintenance and installs directly onto a shaft with bore type Z, suiting applications where a maintenance-free, sealed rolling element bearing is needed at the given shaft diameter and speed range.
