NTN NU2317EG1C3 is an NU type cylindrical roller bearing with a straight 85 mm bore. The NU design features no flanges on the outer ring, making it separable and able to accommodate axial expansion. It has a high strength machined brass cage and C3 clearance. This open bearing is constructed from hardened alloy steel and is suitable for applications requiring high radial load capacity and axial displacement.

How do I choose the right type of bearing for my application?
Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design.
