Dimensions are 95 mm bore by 145 mm outside diameter by 37 mm width, sourced from published NSK specifications for the NN3019 series.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eConstruction features include solid inner and outer rings with separable components for ease of mounting and dismounting.
