Single Row Cylindrical Roller Bearings With Inner Ring NU 217 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NU 217 ECM

The NU 217 ECM is a single row cylindrical roller bearing with an 85mm bore and 150mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 42750 lbf and operates smoothly at speeds up to 5000 RPM.

Its brass cage ensures stable roller movement, while the open design allows easy lubrication with grease or oil. The bearing performs well in temperatures ranging from -30°C to 110°C.

With a width of 28mm and chamfered edges, it fits snugly in tight spaces. This model is interchangeable with SKF bearings, making it a practical choice for replacements.

Ideal for heavy-duty applications like industrial gearboxes or machinery where radial and axial loads are present. Compliant with RoHS and REACH standards, it’s a reliable and safe option. Weighing 2.23kg, it’s sturdy yet manageable for its size.
