Double Row Super-Precision Cylindrical Roller Bearings NN 3019 KTN9/SP

Double Row Super-Precision Cylindrical Roller Bearings NN 3019 KTN9/SP

The NN 3019 KTN9/SP is a double-row cylindrical roller bearing with a 95mm tapered bore and 145mm outer diameter, crafted from high-grade chrome steel. It handles combined loads up to 31950 lbf and reaches speeds of 7000 RPM smoothly.

Its open design allows flexible lubrication with grease or oil, while the PA66 cage ensures stable roller alignment. The bearing operates reliably in temperatures from -30°C to 110°C.

With a 1:12 taper bore, it fits securely on shafts, and its 2mm axial displacement tolerance accommodates slight misalignments. Ideal for precision machinery like spindles or gearboxes where accuracy matters.

Weighing 2.05kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards, it’s interchangeable with SKF equivalents for easy replacements.
