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

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

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

Its open design allows for easy lubrication with grease or oil, while the PA66 cage ensures stable performance. The bearing works reliably in temperatures ranging 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 practical choice for replacements.

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