NTN MUB7309UM is a cylindrical roller bearing with a 45 mm straight bore. This non-separable design features an inner ring with two ribs and an outer ring with one rib, providing axial location in one direction. The open enclosure and hardened alloy steel construction suit moderate-speed industrial gearboxes and pumps.

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.
