WHEELS Mfg Receiver Cup

This receiver cup acts as a critical interface for removing sealed bearings from bicycle bottom brackets. It provides a stable, secure seat for the bearing to be pressed into during the extraction process, preventing damage to your frame or the bearing itself.

It is designed to work with standard threaded rod press handles that accommodate a 0.5-inch thru-hole. While it is highly versatile, you should verify that your specific extractor system utilizes this standard rod size before purchasing.

The machined aluminum provides the necessary rigidity to handle the force required for bearing extraction without deforming. The anodized finish adds a layer of corrosion resistance, ensuring the tool remains durable and easy to clean even after repeated use in a shop environment.

This cup features an inner diameter of 52mm and an outer diameter of 60mm. You should measure the outer race of the bearing you intend to remove to ensure it is compatible with these dimensions; the cup needs to be slightly larger than the bearing to catch it effectively.

While it is primarily engineered for the extraction process, it can be used for installation if the cup diameter matches the outer race of your bearing. However, always ensure you are applying pressure only to the outer race to avoid damaging the bearing internals.
