NTN UC315-215D1 is a standard-duty insert bearing with a 2-15/16 in (74.6 mm) bore, double sealed for contamination resistance. The set screw locking mechanism secures the bearing to the shaft. Constructed with through hardened steel, this insert is designed for use in mounted bearing units such as pillow blocks and flanges for industrial conveyor and machinery applications.

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.
