Single Row Cylindrical Roller Bearings With Inner Ring NU 226 ECJ

Single Row Cylindrical Roller Bearings With Inner Ring NU 226 ECJ

The NU 226 ECJ is a single row cylindrical roller bearing with a 130mm bore and 230mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 93375 lbf and operates smoothly at speeds up to 3000 RPM.

Its open design allows for easy lubrication with grease or oil, while the steel cage ensures stable performance. The bearing works well in temperatures ranging from -30°C to 110°C.

This model is interchangeable with SKF bearings, making it a reliable choice for replacements. Ideal for heavy-duty applications like industrial machinery or gearboxes where radial and axial loads are present.

Weighing 6.28kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe use.

The chamfered edges (3mm) and permissible axial displacement (2.1mm) add to its versatility. Suitable for scenarios requiring precise alignment and durability.
