This accessory routes lubricant to the feed port of the mating unit, forming the link between the supply line and the internal lubrication channel. Catalogue reference SMAD.RWU35-0530 from INA; net mass is 22.8 g, a figure relevant when adding up the weight of a complete assembled set rather than to any load rating. Selection follows the port arrangement and the supply line connection, since the adapter only sets the position and geometry of the lubrication point. It carries no load itself — its function is to keep the grease or oil feed reachable once the unit is installed, including where the port would otherwise be awkward to access. Connecting dimensions can be read from the drawing on this product card.
