The IBC NN 3019.K.W33.M.SP is a double row super precision cylindrical roller bearing manufactured in Germany by IBC Bearings, a Schaeffler Group brand. It carries the NN3019 series designation with a tapered bore (K suffix), W33 lubrication groove and holes in the outer ring, M brass cage, and SP super precision accuracy class. Published dimensions are 95 mm bore, 145 mm outer diameter, and 37 mm width. The tapered bore profile is designed for mounting on tapered adapter sleeves, facilitating precise shaft fit adjustment. This bearing type is commonly used in the main spindles of CNC machining centers and precision machine tools where high radial load capacity and tight running accuracy are required. The double row roller arrangement provides superior radial stiffness compared to single row designs, and the separable outer ring simplifies installation and removal. The W33 groove allows for in-service relubrication through a grease fitting in the housing. The SP accuracy class designation indicates dimensional and running accuracy tolerances meeting ISO P5 or equivalent standards, making this bearing appropriate for precision spindle applications. Part number NN 3019.K.W33.M.SP is confirmed from the original manufacturer label. Country of manufacture is Germany as indicated on the box label.
