Single Row Cylindrical Roller Bearings With Inner Ring NJ 310 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NJ 310 ECM

The NJ 310 ECM is a single-row cylindrical roller bearing with a 50mm bore and 110mm outer diameter, crafted from sturdy chrome steel. It handles combined loads up to 28575 lbf and reaches speeds of 8000 RPM.

Its brass cage keeps rollers centred for smooth operation, while the open design allows easy lubrication with grease or oil. The bearing performs reliably in temperatures from -30°C to 110°C.

With a permissible axial displacement of 1.9mm, it offers flexibility in mounting. Ideal for industrial machinery or gearboxes where radial and axial loads are present.

Weighing 1.34kg, it’s robust yet manageable. Compliant with RoHS and REACH standards, it’s a dependable choice for replacements, interchangeable with SKF bearings.
