Double Row Super-Precision Cylindrical Roller Bearings NN 3026 KTN9/SPC2

Double Row Super-Precision Cylindrical Roller Bearings NN 3026 KTN9/SPC2

The NN 3026 KTN9/SPC2 is a double-row cylindrical roller bearing with a 130mm bore and 200mm outer diameter, built from high-quality chrome steel. It handles combined loads up to 65700 lbf and runs smoothly at speeds up to 5000 RPM.

Its open design allows for easy lubrication with grease or oil, while the PA66 cage ensures smooth operation. The bearing operates well in temperatures from -30°C to 110°C.

With a tapered bore (1:12), it offers secure fitting and can handle axial displacement up to 3mm. This model is interchangeable with SKF bearings, making it a reliable choice for replacements.

Ideal for precision applications like machine tools or industrial gearboxes where high radial loads are common. Weighing 5.5kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe use.
