Single Row Cylindrical Roller Bearings With Inner Ring NUP 311 ECML

Single Row Cylindrical Roller Bearings With Inner Ring NUP 311 ECML

The NUP 311 ECML is a single row cylindrical roller bearing with a 55mm bore and 120mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 35100 lbf and reaches speeds of 11000 RPM.

Its PA66 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.

This model is interchangeable with SKF bearings, making it a practical choice for replacements. Ideal for machinery like pumps or gearboxes where both radial and axial loads are present.

Weighing 1.74kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe industrial use.
