Deep groove ball bearing 6006-TB is a single row radial bearing with a bore diameter of 30.0 mm, outside diameter of 55.0 mm, and width of 13.0 mm. Net mass is 121.68 g. The bearing carries a solid laminated fabric cage (TB), providing stable ball guidance and reduced friction at running speed. Limiting speed is rated at 18500 1/min, with a reference speed of 13100 1/min. Radial internal clearance is CN (Group N), the normal clearance group. The solid laminated fabric cage supports smooth operation at the stated limiting speed and suits applications requiring reliable ball guidance without added axial constraint. Normal internal clearance (CN) makes this bearing suitable for standard mounting conditions without special preload requirements. As an open bearing without integrated sealing, it requires external lubrication and protection from contamination, with grease or oil lubrication selected according to the operating speed range between reference and limiting values.
