This single row deep groove ball bearing carries the bore code 25.0 mm, outside diameter 47.0 mm and width 12.0 mm, with a net mass of 0.075 kg. The cage is a solid laminated fabric type (TB), and radial internal clearance is increased to C3 (Group 3). Limiting speed is rated at 21900 1/min, with a reference speed of 15200 1/min. The C3 clearance compensates for interference fits and thermal expansion under operating temperature rise, keeping the bearing free of preload in applications with tighter fits on shaft or housing. The solid laminated fabric cage (TB) offers stable ball guidance at higher speeds within the stated limiting and reference speed values. As supplied, the bearing is open, without integrated seals or shields, so lubrication and contamination protection must be provided externally.
