Single Row Cylindrical Roller Bearings With Inner Ring N 28/710 ECMB

Single Row Cylindrical Roller Bearings With Inner Ring N 28/710 ECMB

The N 28/710 ECMB is a single-row cylindrical roller bearing with a large 710mm bore and 870mm outer diameter, built from sturdy chrome steel. It handles combined loads up to 436500 lbf and runs smoothly at speeds up to 1000 RPM.

Its brass cage keeps rollers centred for even load distribution, while the open design allows easy lubrication with grease or oil. The bearing operates well in temperatures from -30°C to 110°C.

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

Weighing 127kg, it’s built for durability in demanding environments. Compliant with RoHS and REACH standards for safe use.
