SKF NN3028K/SPW33 — Super-precision cylindrical roller bearing (NN 30xx / N 10xx)
SKF · Bearings & Power Transmission · Super-Precision Cylindrical Roller Bearings
SKF NN3028K/SPW33 super-precision cylindrical roller bearing (nn 30xx / n 10xx). Super-precision (ISO 492 P4A / P2A) double-row (NN 30xx) or single-row (N 10xx) cylindrical roller bearing designed as the non-locating position on a machine-tool spindle. Very high radial rigidity and running accuracy. Tapered bore (K suffix) allows radial preload to be set at assembly. Fitted with a machined brass cage. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options.
