Single Row Cylindrical Roller Bearings With Inner Ring NJ 319 ECP

Single Row Cylindrical Roller Bearings With Inner Ring NJ 319 ECP

The NJ 319 ECP is a single row cylindrical roller bearing with a 95mm bore and 200mm outer diameter, crafted from sturdy chrome steel. It handles combined loads up to 87750 lbf and operates smoothly at speeds up to 4000 RPM.

Its open design allows for easy lubrication with grease or oil, while the PA66 cage ensures durability and centred roller alignment. The bearing performs reliably in temperatures ranging 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 machinery where radial and axial loads are present.

Weighing 6.54kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe and versatile use.
