This deep groove ball bearing carries radial and moderate axial loads in a single row of balls running in a Generation C design, with 55.0 mm bore, 100.0 mm outside diameter and 21.0 mm width. Mass is 0.593 kg, limiting speed reaches 5800 1/min, and the cage is a steel sheet metal type (JN). Radial internal clearance is CN (Group N), and the design includes seals on both sides (2HRS) protecting the raceway from contamination while retaining grease inside. With standard CN clearance and sealed construction, this bearing suits applications requiring protection against dust and moisture without additional external sealing arrangements. The steel sheet metal cage keeps the design compact and suitable for the given speed rating, while the sealed variant eliminates the need for relubrication during service, making mounting and maintenance straightforward within the stated bore and speed limits.
