Stock #: 0226-00212
NSK manufactured the NN3019KCC9P5YU17, a double row super precision cylindrical roller bearing supplied as Mazak OEM part number F04NP000390 for CNC machine tool spindle applications. Dimensions are 95 mm bore by 145 mm outside diameter by 37 mm width, sourced from published NSK specifications for the NN3019 series.
The K suffix indicates a tapered bore with a 1:12 taper, allowing precise adjustment of radial internal clearance during installation on the spindle shaft. The CC9 designation specifies the matched clearance class applicable to ISO Tolerance Class 5 and Class 4 cylindrical roller bearings with tapered bores. The P5 suffix denotes ISO Class 5 precision, the standard accuracy grade for NSK super precision NN30 series spindle bearings. The YU17 suffix is a specialized NSK internal designation tied to OEM application requirements.
Construction features include solid inner and outer rings with separable components for ease of mounting and dismounting. The double row configuration delivers high radial load capacity and rigidity, making this bearing class standard for the front and rear spindle positions of precision lathes, machining centers, and grinding machines. The bearing is supplied open without seals.
Original Mazak packaging is present with the original labeling intact, identifying customer purchase order 7390282, order number 16402, and inventory location 24 16 R4. Quantity supplied is 1 bearing. The Mazak box references the part description ASK 145.11X11 (1:1). This is a stocked spare originally procured through Mazak for use as a CNC machine tool spindle replacement bearing.
