Single Row Cylindrical Roller Bearings With Inner Ring NU 31/530 ECMA/HB1

Single Row Cylindrical Roller Bearings With Inner Ring NU 31/530 ECMA/HB1

The NU 31/530 ECMA/HB1 is a single row cylindrical roller bearing with a large 530mm bore and 870mm outer diameter, built from sturdy chrome steel. It handles combined loads up to 1,683,000 lbf and runs smoothly at speeds up to 1000 RPM.

Its brass cage, centred on the outer ring, ensures durability and reduces friction. The open design allows for easy lubrication with grease or oil, and it operates well in temperatures from -30°C to 110°C.

This bearing is interchangeable with SKF models, making it a reliable choice for replacements. Ideal for heavy-duty applications like industrial machinery or large gearboxes where high radial loads are common.

Weighing 660kg, it’s a robust option for demanding environments. Compliant with RoHS and REACH standards for safe and sustainable use.
