This deep groove ball bearing carries radial and moderate axial loads on a shaft of 20.0 mm bore, with an outside diameter of 42.0 mm and a width of only 8.0 mm, giving a low-profile design for a net mass of 51.0 g. It is a single row design fitted with shields on both sides and a steel sheet metal cage (JN), keeping the rolling elements protected while allowing free rotation. Limiting speed is rated at 22100.0 1/min, with a reference speed of 13800.0 1/min. Radial internal clearance is CN (Group N), the standard clearance class, suitable for normal fit and temperature conditions without preload issues. The shielded design (bore type Z) restricts ingress of coarse contamination while retaining grease inside the bearing, so it works without additional external sealing where periodic relubrication is not required. The slim width and standard clearance make it suitable for compact housings where radial space is limited but shaft speeds stay within the stated limiting and reference values.
