This part is specifically the outer race of the bearing. It is made for Busch R5 models 0400B, 0502B, and 0630B. Using the correct bearing is key for maintaining your pump’s performance This bearing uses many small, cylindrical rollers. These rollers are called “needles” because of their shape. They sit inside this race. The design allows the pump to handle high loads in a very compact space. This reduces wear on other parts.
