NN3018K/SPW33 Double Row Cylindrical Roller Bearing 90x140x37 Mm
NN3018K/SPW33 Double Row Cylindrical Roller Bearing 90x140x37 mm
Super-precision double row cylindrical roller bearings in the NN 30 series provide a unique balance between load carrying capacity, rigidity and speed. Having three flanges on the inner ring and no flanges on the outer ring, the bearings can accommodate axial displacement in both directions. The separable design simplifies mounting and dismounting, particularly when load conditions require both rings to have an interference fit.
K: Tapered bore, taper 1:12
SP: Special Precision Class For Machine Tool Bearings: Dimensional Accuracy Approximately To P5, Running Accuracy Approximately To P4.
W33: Lubrication Groove And Three Holes In Bearing Outer Ring.
