Double row roller or ball wheel bearings, composed of two interior sets housed in one outer ring, can withstand large radial and axial loads in both directions. They allow for rigid bearing arrangements and are suitable for bearing arrangements where rigid axial guidance is required.
The double row roller or ball wheel bearing design allows for space saving applications, and in many cases the bearing requires no maintenance since it is lubricated for
life.
