Carrying radial loads at a fixed shaft position, this single row deep groove ball bearing accommodates the 50.0 mm bore, 80.0 mm outside diameter and 16.0 mm width range. Both sides are fitted with shields, and the rolling elements run in a steel sheet metal cage (JN). Internal clearance is set to CN (Group N), with a limiting speed of 10400 1/min and a reference speed of 8900 1/min; net mass is 0.262 kg. The shielded design keeps the raceway protected from coarse contaminants while retaining grease fill inside the bearing, so relubrication intervals depend on running conditions rather than open exposure. CN clearance suits standard mounting fits without preload, and the steel cage allows operation across the stated speed range without cage deformation. Dimensionally and constructionally this bearing corresponds to SKF 6010-2Z, NSK 6010ZZ and NTN 6010ZZ.
