Zero-Clearance (ZV) Preload
The ZV designation is not a marketing label—it denotes a bearing that is internally preloaded at the factory. There is no axial or radial clearance to take up during installation, which means the steering shaft is located precisely from the first turn of the wheel. For steering systems, this eliminates the “dead zone” that develops as clearance bearings wear in.
Four-Point Contact Geometry
The QJ series raceway accommodates combined radial and axial loads in a compact envelope. In steering column applications, this geometry provides high stiffness without the axial height penalty of paired angular contact bearings.
Integrated Flange, No Machining Required
The flange acts as a built-in shoulder, positioning the bearing in the housing without additional spacers, snap rings, or shaft machining. This reduces installation time and eliminates a common source of misalignment in steering column rebuilds.
Low Torque, High Stiffness
The preloaded design is tuned to balance stiffness against friction torque. The result is steering feel that is firm and precise without introducing excessive resistance or noise—a critical compromise in electric power steering (EPS) systems where torque sensing accuracy matters
