Double Row Super-Precision Cylindrical Roller Bearings NN 3018 KTN9/SPVM127

Double Row Super-Precision Cylindrical Roller Bearings NN 3018 KTN9/SPVM127

The NN 3018 KTN9/SPVM127 is a double-row cylindrical roller bearing with a 90mm bore and 140mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 31050 lbf and reaches speeds of 7000 RPM.

Its tapered bore design ensures a secure fit, while the open seal allows for easy lubrication with grease or oil. The PA66 cage keeps rollers centred for smooth operation.

This bearing suits applications with high radial loads, such as machine tools or industrial gearboxes. It performs reliably in temperatures from -30°C to 110°C.

Weighing 1.95kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards, it’s interchangeable with SKF models for easy replacement.
