features
- The housing bore and shaft must be hardened and machined
- 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)
- Available in inch (WJ) and metric (K) sizes
- Best used for applications that require maximum radial load capacity and a thin cross section
