NTN MU1312UM is a heavy-industrial cylindrical roller bearing with a 60 mm straight bore. It features a non-separable design with two ribs on the inner ring and one rib on the outer ring, plus a retaining ring. The open enclosure and machined brass cage support high-load applications in gearboxes and mill housings.

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.
