# Timken 384ED-3 Precision Tapered Roller Bearing Cup, <4 in OD, Class -3 - MROSupply.com

***Timken 384ED-3 is a precision tapered roller bearing cup (outer ring) for industrial applications requiring high accuracy. This single cup features a precision class -3 suffix, indicating ABEC 5 (ISO Class 5) tolerance for reduced runout in gearboxes and pump shafts. It is part of the <4 inch outside diameter size class. Precision cups are matched with corresponding cones to form a complete bearing assembly for locating and supporting rotating shafts under combined radial and thrust loads.***

## FAQ:

- 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.
