NTN NN3036NAP4 is a double row cylindrical roller bearing with a 180 mm straight bore. The NN type configuration has no flanges on the outer ring, allowing axial expansion. It features a high-strength, two-piece machined brass cage and is open (unsealed). Suitable for heavy-duty industrial applications requiring high radial load capacity and rigidity.

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.
