- Best used to provide maximum radial load capacity (full complement of rollers no cage) for thin cross section applications
- A hardened and machined shaft or an "IR" Inner Ring is required for optimal performance
- A press fit into the housing is required
- Available with an oil hole (-OH)
- Available with a precision ground outside diameter (GB style) for applications that require higher precision and/or two bearings mounted side by side
- Available with heavy duty rollers (BH style) for applications that require maximum radial load capacity
- Available with a closed end (M)
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.
