Collection: Frame Pivot Bearing

A bike pivot bearing refers to a specific type of bearing used in bicycle suspension systems. In full-suspension mountain bikes or other bikes with pivot points, such as rear suspension linkages or swing arms, pivot bearings are used to allow smooth rotation and movement of these components.

The term "pivot bearing" generally refers to a type of cartridge bearing, typically ball or roller bearings, enclosed within a housing or a bearing cup. These bearings are designed to handle both radial loads (forces applied perpendicular to the axis of rotation) and axial loads (forces applied parallel to the axis of rotation). This allows the pivot points to move freely while supporting the weight of the rider and absorbing the forces encountered during off-road riding or other challenging conditions.

Pivot bearings are typically made from materials such as steel or ceramic, and they are sealed to protect them from dirt, moisture, and contaminants that could affect their performance or longevity. Regular maintenance, such as cleaning and lubrication, is important to ensure the smooth operation of pivot bearings and to prevent premature wear.

It's worth noting that there are various types and designs of pivot bearings used in different bike models and suspension systems, and the specific configuration can vary. Some common types include cartridge bearings, needle bearings, or bushings. The choice of pivot bearing design depends on factors such as the bike's intended use, the load requirements, and the desired performance characteristics.
