Single Row Cylindrical Roller Bearings With Inner Ring NJ 2217 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NJ 2217 ECM

The NJ 2217 ECM is a single-row cylindrical roller bearing with an 85mm bore and 150mm outer diameter, crafted from sturdy chrome steel. It handles combined loads up to 56250 lbf and runs smoothly at speeds up to 5000 RPM.

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

With a 36mm width and 2mm chamfer dimensions, it fits snugly in tight spaces. The inner ring design ensures stability under axial displacement up to 2mm.

Ideal for heavy-duty machinery like gearboxes or pumps, where radial and axial loads are present. Compliant with RoHS and REACH standards, it’s a reliable choice for industrial applications. Weighing 2.84kg, it balances strength and practicality.
