This single row deep groove ball bearing carries a 45.0 mm bore, 75.0 mm outside diameter and 16.0 mm width, with a net mass of 0.241 kg. Radial loads are supported by a single row of balls guided in a steel sheet metal cage (JN), and the design includes shields on both sides for protection against contamination. Radial internal clearance is in the CN (Group N) range. The limiting speed is 11200 1/min, with a reference speed of 9700 1/min. The shielded construction retains factory-applied grease and reduces the need for maintenance, while limiting protection against fine dust or liquid ingress. Standard CN clearance makes this bearing suitable for general-purpose radial mounting without special preload or fit adjustments. Dimensionally and constructionally equivalent to SKF 6009-2Z, NSK 6009ZZ and NTN 6009ZZ.
