Double Row Super-Precision Cylindrical Roller Bearings NN 3022 KTN9/SPVR5220

Double Row Super-Precision Cylindrical Roller Bearings NN 3022 KTN9/SPVR5220

The NN 3022 KTN9/SPVR5220 is a double-row cylindrical roller bearing with a 110mm bore and 170mm outer diameter, built from tough chrome steel. It handles combined loads up to 49500 lbf and runs smoothly at speeds up to 6000 RPM.

Its open design allows easy lubrication with grease or oil, while the PA66 cage keeps rollers centred for stable performance. The bearing operates well in temperatures from -30°C to 110°C.

This model is interchangeable with SKF bearings, making it a practical choice for replacements. Ideal for heavy machinery or precision equipment where high radial and axial loads are present.

Weighing 3.4kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe use.
