This deep groove ball bearing carries radial and limited axial loads with a single row of balls running in a steel sheet metal cage (JN). Bore diameter is 9.0 mm, outside diameter 17.0 mm, width 4.0 mm, and net mass is 3.41 g. The limiting speed reaches 58000 1/min, with a reference speed of 27000 1/min, and the bore type is designated Z. Radial internal clearance falls within the CN (Group N) range, giving a standard fit suitable for typical shaft and housing tolerances without excessive play or preload. The steel sheet metal cage keeps ball guidance stable at higher speeds while maintaining low friction and low mass, matching the compact 9x17x4 mm envelope. No integrated seal or shield is specified, so lubrication and contamination protection must be provided externally in the application.
