This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore of 55.0 mm, outside diameter of 120.0 mm, and width of 29.0 mm. Net mass is 1.35 kg, and the limiting speed reaches 5300.0 1/min. It is fitted with a steel sheet metal cage (JN) and seals on both sides (2HRS), running with C3 radial internal clearance. The C3 clearance suits operating conditions with elevated temperature or tighter fits where a standard clearance would run too tight, while the two-sided sealing keeps grease in and contaminants out, allowing operation without external relubrication for the service life of the grease fill. The steel sheet metal cage gives stable ball guidance at the stated limiting speed, and Generation C design allows use as a direct dimensional match within the 63.. series for the given bore, outside diameter, and width.
