Black Bearing radial bearings are machined and assembled to precise tolerances. They are offered in four material/build options to suit a broad range of applications at any budget.
These bearings are best suited to components that undergo continuous rotation - think hubs, bottom brackets, or any part that spins. While they can be used in suspension pivots, the full-complement MAX versions are best suited to this application for optimum load management and longevity.
