If a layer of paint is present, the rim will no longer slide smoothly onto the hub lip or will bind under tension. These plugs are specifically designed for such large openings: they seal center bores, bearing seats, and pipes with inside diameters from 48 to 102 mm, withstand the heat in the curing oven, and pull out cleanly in one piece afterward. You can purchase each size individually, ideal for a set of rims or a single component.\u003c\/p\u003e\n\u003cp\u003eFor bores under 48 mm, seal them using our \u003ca href=\"https:\/\/pulverlackfachhandel.de\/en\/products\/silicone-plug-conical-medium\"\u003emedium sizes for 20 to 53 mm\u003c\/a\u003e.

Aftermarket wheels often feature a larger center bore and are fitted using centering rings. This ring must also slide in smoothly post-coating. Be sure to remove plastic and aluminum centering rings prior to coating.\u003c\/p\u003e\n\u003cp\u003eAt least equally critical is the hub mounting face, the flat mating surface on the back of the rim where it rests against the wheel hub. Paint left between the rim and hub will yield under bolt torque, causing the connection to loosen over time. Insert the plug from the backside into the center bore and mask the surrounding mounting face with\u0026nbsp;\u003ca href=\"https:\/\/pulverlackfachhandel.de\/en\/collections\/masking-tape-heat-resistant\"\u003eheat-resistant tape\u003c\/a\u003e.

By contrast, an 80 µm powder layer reduces the seat diameter by 0.16 mm. As a result, the bearing will no longer fit, or the outer ring will deform during press-fitting, causing the bearing to run rough. Cast aluminum motorcycle wheel hubs should also be outgassed before masking. To understand why this is so important for castings, read our guide on \u003ca href=\"https:\/\/pulverlackfachhandel.de\/en\/blogs\/magazin\/powder-coating-aluminium-guide-costs\"\u003epowder coating aluminum\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eIf wheel studs are still present in the hub, protect their threads using \u003ca href=\"https:\/\/pulverlackfachhandel.de\/en\/products\/silicone-caps-heatresistant\"\u003esilicone caps\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003ePosts, Railings, and Pipe Stubs\u003c\/h3\u003e\n\u003cp\u003eFence and post tubes measuring 76.1 or 88.9 mm outer diameter are frequently coated prior to assembly. The plug keeps the tube end clear so post caps and connectors fit smoothly without post-processing. The same applies to engine intake and air filter stubs, where hoses must seal tightly.\u003c\/p\u003e\n\u003ch2\u003eDimensions Table for Center Bores, Bearing Seats, and Tubing\u003c\/h2\u003e\n\u003cp\u003eYou can find the center bore diameter of your aftermarket rim in its technical approval document (TÜV report). For tubing and bearing seats, measure with the internal jaws of a caliper at a minimum of two points, as large openings are rarely perfectly round. The plug fits best when your measurement falls roughly near the middle of its specified range.\u003c\/p\u003e\n\u003cdiv style=\"margin: 16px 0px; -ms-overflow-x: auto;\"\u003e\n\u003ctable style=\"width: 100%;
