This deep groove ball bearing carries radial and moderate axial loads through a single row of balls guided by a steel sheet metal cage (JN). Bore diameter is 40.0 mm, outside diameter 80.0 mm, width 23.0 mm, and net mass is 0.461 kg. The limiting speed reaches 5000.0 1/min, and radial internal clearance is CN (Group N), the standard clearance group. The bearing is sealed on both sides (2RSR), which keeps grease inside and prevents contaminants from entering the raceway area, so relubrication during service is not required. Standard CN clearance suits general rotating applications without unusual shaft deflection or thermal expansion demands. The steel sheet metal cage keeps mass low while guiding the balls reliably at the stated speed rating.
