- Best used for applications that require maximum radial load capacity and a thin cross section
- Most sizes use a hardened steel cage (no callout)
- A polymer cage (TN in suffix) is used on our smallest metric sizes (4-8mm bore)
- The housing bore and shaft must be hardened and machined
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.
