FAQ

What does the ‘ECP’ suffix mean for the SKF NU 204 ECP?

The ‘ECP’ suffix indicates specific design features. ‘E’ stands for an optimized internal design for increased load carrying capacity. ‘C’ represents an optimized roller end/flange contact. ‘P’ signifies a glass fibre reinforced PA66 (polyamide) cage, which is lightweight and suitable for high speeds.

Is this bearing suitable for applications with axial loads?

No, NU design cylindrical roller bearings like the NU 204 ECP are designed to accommodate high radial loads only. They cannot take any axial load. For combined loads, you would need a different type of bearing, such as an angular contact ball bearing.

What type of lubrication is recommended for the NU 204 ECP?

The appropriate lubrication depends on the operating conditions (speed, temperature, load). This bearing can be lubricated with either grease or oil. For high-speed applications, oil lubrication is often preferred. Always refer to the machine manufacturer’s manual or consult a lubrication expert for the specific application.
